Subject: [PATCH 001/906] PR19767: DebugInfo emission of pointer constants.

In refactoring DwarfUnit::isUnsignedDIType I restricted it to only work
on values with signedness (unsigned or signed), asserting on anything
else (which did uncover some bugs). But it turns out that we do need to
emit constants of signless data, such as pointer constants - only null
pointer constants are known to need this so far, but it's conceivable
that there might be non-null pointer constants at some point (hardcoded
address offsets for device drivers?).

This patch just uses 'unsigned' for signless data such as pointer
constants. Arguably we could use signless representations
(DW_FORM_dataN) instead, allowing a trinary result from isUnsignedDIType
(signed, unsigned, signless), but this seems reasonable for now.

Subject: [PATCH 002/906] Rewrite calculateDbgValueHistory to make it
 (hopefully) more transparent.

This change preserves the original algorithm of generating history
for user variables, but makes it more clear.

High-level description of algorithm:
Scan all the machine basic blocks and machine instructions in the order
they are emitted to the object file. Do the following:
1) If we see a DBG_VALUE instruction, add it to the history of the
corresponding user variable. Keep track of all user variables, whose
locations are described by a register.
2) If we see a regular instruction, look at all the registers it clobbers,
and terminate the location range for all variables described by these registers.
3) At the end of the basic block, terminate location ranges for all
user variables described by some register.

Although this change shouldn't be user-visible (the contents of .debug_loc section
should be the same), it changes some internal assumptions about the set
of instructions used to track the variable locations. Watching the bots.

Subject: [PATCH 004/906] GlobalValue: Automatically reset visibility when
 setting local linkage

r208264 started asserting in `setLinkage()` and `setVisibility()` that
visibility and linkage are compatible.  There are a few places in clang
where visibility is set first, and then linkage later, so the assert
fires.  In `setLinkage()`, it's clear what the visibility *should* be,
so rather than updating all the call sites just automatically fix the
visibility.

The testcase for this is for *clang*, so it'll follow separately in cfe.

Subject: [PATCH 005/906] [LSR] Canonicalize reg1 + ... + regN into reg1 + ...
 + 1*regN.

This commit introduces a canonical representation for the formulae.
Basically, as soon as a formula has more that one base register, the scaled
register field is used for one of them. The register put into the scaled
register is preferably a loop variant.
The commit refactors how the formulae are built in order to produce such
representation.
This yields a more accurate, but still perfectible, cost model.

Subject: [PATCH 008/906] Move the function and data section flags into the
 options struct and make the functions to set them non-static. Move and rename
 the llvm specific backend options to avoid conflicting with the clang option.

Subject: [PATCH 009/906] Unbreak the sanitizer buildbots after r209226 due to
 SROA issue described in http://reviews.llvm.org/D3714

Undecided whether this should include a test case - SROA produces bad
dbg.value metadata describing a value for a reference that is actually
the value of the thing the reference refers to. For now, loosening the
assert lets this not assert, but it's still bogus/wrong output...

If someone wants to tell me to add a test, I'm willing/able, just
undecided. Hopefully we'll get SROA fixed soon & we can tighten up this
assertion again.

Subject: [PATCH 010/906] [ARM64] PR19792: Fix cycle in DAG after
 performPostLD1Combine

Povray and dealII currently assert with "Overran sorted position" in
AssignTopologicalOrder.  The problem is that performPostLD1Combine can
introduce cycles.

Consider:

(insert_vector_elt (INSERT_SUBREG undef,
                                  (load (add %vreg0, Constant<8>), undef),  <= A
                                  TargetConstant<2>),
                   (load %vreg0, undef),                                    <= B
                   Constant<1>)

This is turned into a LD1LANEpost node.  However the address in A is not a
valid user of the post-incremented address of B in LD1LANEpost.

Subject: [PATCH 011/906] Revert "DebugInfo: Assume all subprogram DIEs have
 been created before any abstract subprograms are constructed."

This reverts commit r209178.

This seems to be asserting in an LTO build on some internal Apple
buildbots. No upstream reproduction (and I don't have an LLVM-aware gold
built right now to reproduce it personally) but it's a small patch & the
failure's semi-plausible so I'm going to revert first while I try to
reproduce this.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

To make this change other uses of MachOObjectFile::getSymbolAddress
are updated to handle when the Value is returned as UnknownAddressOrSize.
Which is needed to keep two of the ExecutionEngine tests working for example.

Subject: [PATCH 018/906] ARM: correct bundle generation for MOV32T relocations

Although the previous code would construct a bundle and add the correct elements
to it, it would not finalise the bundle.  This resulted in the InternalRead
markers not being added to the MachineOperands nor, more importantly, the
externally visible defs to the bundle itself.  So, although the bundle was not
exposing the def, the generated code would be correct because there was no
optimisations being performed.  When optimisations were enabled, the post
register allocator would kick in, and the hazard recognizer would reorder
operations around the load which would define the value being operated upon.

Rather than manually constructing the bundle, simply construct and finalise the
bundle via the finaliseBundle call after both MIs have been emitted.  This
improves the code generation with optimisations where IMAGE_REL_ARM_MOV32T
relocations are emitted.

The changes to the other tests are the result of the bundle generation
preventing the scheduler from hoisting the moves across the loads.  The net
effect of the generated code is equivalent, but, is much more identical to what
is actually being lowered.

Subject: [PATCH 020/906] MC: mark COFF .drectve section as REMOVE

The .drectve section should be marked as IMAGE_SCN_LNK_REMOVE.  This matches what
the MSVC toolchain does and accurately reflects that this section should not be
emitted into the final binary.  This section is merely information for the
linker, comprising of additional linker directives.

Subject: [PATCH 022/906] [asm matcher] Fix incorrect assertion when there are
 exactly 32 SubtargetFeatures

Summary:
The minimal type needs to hold a value of '1ULL << 31' but
getMinimalTypeForRange() is called with a value of '1ULL << 32'.

This patch will also reduce the size of the matcher table when there are 8
or 16 SubtargetFeatures.

Also added a dump of the SubtargetFeatures to the -debug output and corrected getMinimalTypeInRange() to consider 0xffffffffull to be a 32-bit value.

The testcase is that no existing code is broken and that LLVM still successfully
compiles after adding MIPS64r6 CodeGen support.

Permit active macro expansions when terminating the assembler if there were
errors during the expansion.  This would only trigger on invalid input when
built with assertions.

Subject: [PATCH 031/906] [X86] Fix a bug in the lowering of BLENDI introduced
 in r209043. ISD::VSELECT mask uses 1 to identify the first argument and 0 to
 identify the second argument. On the other hand, BLENDI uses 0 to identify
 the first argument and 1 to identify the second argument. Fix the generation
 of the blend mask to account for this difference.

The bug did not show up with r209043, because we were not checking for the
actual arguments of the blend instruction!
This commit also fixes the test cases.

Note: The same mask works for the BLENDr variant because the arguments are
swapped during instruction selection (see the BLENDXXrr patterns).

<rdar://problem/16975435>

Subject: [PATCH 038/906] DebugInfo: Use the SPMap to find the parent CU of
 inlined functions as they may not be in the current CU

Committed in r209178 then reverted in r209251 due to LTO breakage,
here's a proper fix for the case of the missing subprogram DIE. The DIEs
were there, just in other compile units. Using the SPMap we can find the
right compile unit to search for and produce cross-unit references to
describe this kind of inlining.

One existing test case needed to be updated because it had a function
that wasn't in the CU's subprogram list, so it didn't appear in the
SPMap.

Subject: [PATCH 039/906] MC: introduce ability to restrict recorded
 relocations

Add support to allow a target specific COFF object writer to restrict the
recorded resolutions in the emitted object files.  This is motivated by the need
in Windows on ARM, where an intermediate relocation needs to be prevented from
being emitted in the object file.

Subject: [PATCH 040/906] MC: correct IMAGE_REL_ARM_MOV32T relocation emission

This corrects the emission of IMAGE_REL_ARM_MOV32T relocations.  Previously, we
were avoiding the high portion of the relocation too early.  If there was a
section-relative relocation with an offset greater than 16-bits (65535), you
would end up truncating the high order bits of the offset.  Allow the current
relocation representation to flow through out the MC layer to the object writer.
Use the new ability to restrict recorded relocations to avoid emitting the
relocation into the final object.

 comdat sections."

This reverts commit r208930, r208933, and r208975.

It seems not all fission consumers are ready to handle this behavior.
Reverting until tools are brought up to spec.

Subject: [PATCH 046/906] Fix a bug in SCEV's backedge taken count computation
 from my prior fix in Jan.

This has to do with the trip count computation for loops with multiple
exits, which is quite subtle. Most passes just ask for a single trip
count number, so we must be conservative assuming any exit could be
taken.  Normally, we rely on the "exact" trip count, which was
correctly given as "unknown". However, SCEV also gives a "max"
back-edge taken count. The loops max BE taken count is conservatively
a maximum over the max of each exit's non-exiting iterations
count. Note that some exit tests can be skipped so the max loop
back-edge taken count can actually exceed the max non-exiting
iterations for some exits. However, when we know the loop *latch*
cannot be skipped, we can directly use its max taken count
disregarding other exits. I previously took the minimum here without
checking whether the other exit could be skipped. The correct, and
simpler thing to do here is just to directly use the loop latch's max
non-exiting iterations as the loops max back-edge count.

In the problematic test case, the first loop exit had a max of zero
non-exiting iterations, but could be skipped. The loop latch was known
not to be skipped but had max of one non-exiting iteration. We
incorrectly claimed the loop back-edge could be taken zero times, when
it is actually taken one time.

Fixes Loop %for.body.i: <multiple exits> Unpredictable backedge-taken count.
Loop %for.body.i: max backedge-taken count is 1.

Subject: [PATCH 058/906] MC: formalise some assertions into proper errors

Now that clang can be used as an assembler via the IAS, invalid assembler inputs
would cause the assertions to trigger.  Although we cannot recover from the
errors here, nor provide caret diagnostics, attempt to handle them slightly more
gracefully by reporting a fatal error.

Subject: [PATCH 060/906] ARM: introduce llvm.arm.undefined intrinsic

This intrinsic permits the emission of platform specific undefined sequences.
ARM has reserved the 0xde opcode which takes a single integer parameter (ignored
by the CPU).  This permits the operating system to implement custom behaviour on
this trap.  The llvm.arm.undefined intrinsic is meant to provide a means for
generating the target specific behaviour from the frontend.  This is
particularly useful for Windows on ARM which has made use of a series of these
special opcodes.

Should be no change in behaviour, but it makes the intended

real extend operations.

Subject: [PATCH 065/906] [mips][mips64r6] Add b[on]vc

Summary:
This required me to implement the disassembler for MIPS64r6 since the encodings
are ambiguous with other instructions. This in turn revealed a few
assembly/disassembly bugs which I have fixed.

* da[ht]i only take two operands according to the spec, not three.
* DecodeBranchTarget2[16] correctly handles wider immediates than simm16
  * Also made non-functional change to DecodeBranchTarget and
    DecodeBranchTargetMM to keep implementation style consistent between
    them.
* Difficult encodings are handled by a custom decode method on the most
  general encoding in the group. This method will convert the MCInst to a
  different opcode if necessary.

DecodeBranchTarget is not currently the inverse of getBranchTargetOpValue
so disassembling some branch instructions emit incorrect output. This seems
to affect branches with delay slots on all MIPS ISA's. I've left this bug
for now and temporarily removed the check for the immediate on
bc[12]eqz/bc[12]nez in the MIPS32r6/MIPS64r6 tests.

jialc and jic crash the disassembler for some reason. I've left these
instructions commented out for the moment.

Depends on D3760

Subject: [PATCH 066/906] [mips][mips64r6] Test that paired single instructions
 are invalid

Summary:
These emit the 'unknown instruction' instead of the correct error
because they have not been implemented in LLVM for any MIPS ISA.

Subject: [PATCH 069/906] [mips] Use addiu in inline assembly tests since addi
 is not available in all ISA's

Summary:
This patch is necessary so that they do not fail on MIPS32r6/MIPS64r6 when
-integrated-as is enabled by default and we correctly detect the host CPU.

No functional change since these tests are testing the behaviour of the
constraint used for the third operand rather than the mnemonic.

Depends on D3842

Subject: [PATCH 070/906] [mips] Change lwl and lwr in inlineasm_constraint.ll
 to lw

Summary:
lwl and lwr are not available in MIPS32r6/MIPS64r6. The purpose of the test
is to check that the '$1' expands to '0($x)' rather than to test something related
to the lwl or lwr instructions so we can simply switch to lw.

Depends on D3842

Subject: [PATCH 071/906] [mips] Make unalignedload.ll test stricter and easier
 to modify for MIPS32r6/MIPS64r6

Summary:
* Split into two functions, one to test each struct.
* R0 and R2 must be defined by an lw with a %got reference to the correct
  symbol.
* Test for $4 (first argument) where appropriate instead of accepting any
  register.
* Test that the two lbu's are correctly combined into $4

Depends on D3844

Subject: [PATCH 072/906] ARM64: separate load/store operands to simplify
 assembler

This changes ARM64 to use separate operands for each component of an
address, and look for separate '[', '$Rn, ..., ']' tokens when
parsing.

This allows us to do away with quite a bit of special C++ code to
handle monolithic "addressing modes" in the MC components. The more
incremental matching of the assembler operands also allows for better
diagnostics when LLVM is presented with invalid input.

Most of the complexity here is with the register-offset instructions,
which were extremely dodgy beforehand: even when the instruction used
wM, LLVM's model had xM as an operand. We papered over this
discrepancy before, but that approach doesn't work now so I split them
into separate X and W variants.

Subject: [PATCH 073/906] ARM64: model pre/post-indexed operations properly.

We should be keeping track of the writeback on these instructions,
otherwise we're relying on LLVM's stupidity for correct code.

Fortunately, the MC layer can now handle all required constraints,
which means we can get rid of the CodeGen only PseudoInsts too.

Subject: [PATCH 077/906] Add support for missed and analysis optimization
 remarks.

Summary:
This adds two new diagnostics: -pass-remarks-missed and
-pass-remarks-analysis. They take the same values as -pass-remarks but
are intended to be triggered in different contexts.

-pass-remarks-missed is used by LLVMContext::emitOptimizationRemarkMissed,
which passes call when they tried to apply a transformation but
couldn't.

-pass-remarks-analysis is used by LLVMContext::emitOptimizationRemarkAnalysis,
which passes call when they want to inform the user about analysis
results.

The patch also:

1- Adds support in the inliner for the two new remarks and a
   test case.

2- Moves emitOptimizationRemark* functions to the llvm namespace.

3- Adds an LLVMContext argument instead of making them member functions
   of LLVMContext.

Subject: [PATCH 079/906] [X86] Improve the lowering of BITCAST from MVT::f64
 to MVT::v4i16/MVT::v8i8.

This patch teaches the x86 backend how to efficiently lower ISD::BITCAST dag
nodes from MVT::f64 to MVT::v4i16 (and vice versa), and from MVT::f64 to
MVT::v8i8 (and vice versa).

This patch extends the logic from revision 208107 to also handle MVT::v4i16
and MVT::v8i8. Also, this patch correctly propagates Undef values when
performing the widening of a vector (example: when widening from v2i32 to
v4i32, the upper 64bits of the resulting vector are 'undef').

Subject: [PATCH 080/906] Remove LLVMContextImpl::optimizationRemarkEnabledFor.

Summary:
This patch moves the handling of -pass-remarks* over to
lib/DiagnosticInfo.cpp. This allows the removal of the
optimizationRemarkEnabledFor functions from LLVMContextImpl, as they're
not needed anymore.

Reviewers: qcolombet

Subscribers: llvm-commits

Subject: [PATCH 089/906] R600: Try to convert BFE back to standard bit ops
 when possible.

This allows existing DAG combines to work on them, and then
we can re-match to BFE if necessary during instruction selection.

Subject: [PATCH 090/906] R600: Add definition for flat address space ID.

Use 4 since that's probably what it will be for spir.
Move ADDRESS_NONE to the end to keep the constant_buffer_* values
unchanged, since apparently a bunch of r600 tests use those directly.

Subject: [PATCH 092/906] [RuntimeDyld] Teach RuntimeDyldMachO how to handle
 scattered VANILLA relocs on i386.

This fixes two more MCJIT regression tests on i386:

  ExecutionEngine/MCJIT/2003-05-06-LivenessClobber.ll
  ExecutionEngine/MCJIT/2013-04-04-RelocAddend.ll

The implementation of processScatteredVANILLA is tasteless (*ba-dum-ching*),
but I'm working on a substantial tidy-up of RuntimeDyldMachO that should
improve things.

This patch also fixes a type-o in RuntimeDyldMachO::processSECTDIFFRelocation,
and teaches that method to skip over the PAIR reloc following the SECTDIFF.

Subject: [PATCH 094/906] [Graph Writer] Limit the length of the graph name
 because Windows can't handle it.

Windows can't handle paths longer than 260 code points without \\?\. Even
with \\?\ it can't handle path components longer than 255 code points. So
limit graph names to the arbitrary length of 140. Random characters are still
added to the end, so it's ok if graph names collide.

 isKnownPredicate

ScalarEvolution::isKnownPredicate() can wrongly reduce a comparison
when both the LHS and RHS are SCEVAddRecExprs. This checks that both
LHS and RHS are guarded in the case when both are SCEVAddRecExprs.

The test case is against indvars because I could not find a way to
directly test SCEV.

Subject: [PATCH 098/906] MC: remove unnecessary restriction on tests

Rafael correctly pointed out that the restriction is unnecessary.  Although the
tests are intended to ensure that we dont abort due to an assertion, running the
tests in all modes is better since it also ensures that we dont crash without
assertions.  Always run these tests to ensure that we can handle invalid input
correctly.

It's not really a "ScopeDIE", as such - it's the abstract function
definition's DIE. And we usually use "SP" for subprograms, rather than
"Sub".

Subject: [PATCH 104/906] [YAML] Add an optional argument `EnumMask` to the
 `yaml::IO::bitSetCase()`.

Some bit-set fields used in ELF file headers in fact contain two parts.
The first one is a regular bit-field. The second one is an enumeraion.
For example ELF header `e_flags` for MIPS target might contain the
following values:

Bit-set values:

  EF_MIPS_NOREORDER = 0x00000001
  EF_MIPS_PIC       = 0x00000002
  EF_MIPS_CPIC      = 0x00000004
  EF_MIPS_ABI2      = 0x00000020

Enumeration:

  EF_MIPS_ARCH_32   = 0x50000000
  EF_MIPS_ARCH_64   = 0x60000000
  EF_MIPS_ARCH_32R2 = 0x70000000
  EF_MIPS_ARCH_64R2 = 0x80000000

For printing bit-sets we use the `yaml::IO::bitSetCase()`. It does not
support bit-set/enumeration combinations and prints too many flags from
an enumeration part. This patch fixes this problem. New method
`yaml::IO::maskedBitSetCase()` handle "enumeration" part of bitset
defined by provided mask.

Patch reviewed by Nick Kledzik and Sean Silva.

Subject: [PATCH 106/906] Updated the llvm.mem.parallel_loop_access semantics
 to include the possibility to have only some of the loop's memory
 instructions be annotated and still _help_ the loop carried dependence
 analysis.

This was discussed in the llvmdev ML (topic: "parallel loop metadata question").

 '``llvm.mem.parallel_loop_access``' Metadata
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-For a loop to be parallel, in addition to using
-the ``llvm.loop`` metadata to mark the loop latch branch instruction,
-also all of the memory accessing instructions in the loop body need to be
-marked with the ``llvm.mem.parallel_loop_access`` metadata. If there
-is at least one memory accessing instruction not marked with the metadata,
-the loop must be considered a sequential loop. This causes parallel loops to be
-converted to sequential loops due to optimization passes that are unaware of
-the parallel semantics and that insert new memory instructions to the loop
-body.
+The ``llvm.mem.parallel_loop_access`` metadata refers to a loop identifier, 
+or metadata containing a list of loop identifiers for nested loops. 
+The metadata is attached to memory accessing instructions and denotes that 
+no loop carried memory dependence exist between it and other instructions denoted 
+with the same loop identifier.
+
+Precisely, given two instructions ``m1`` and ``m2`` that both have the 
+``llvm.mem.parallel_loop_access`` metadata, with ``L1`` and ``L2`` being the 
+set of loops associated with that metadata, respectively, then there is no loop 
+carried dependence between ``m1`` and ``m2`` for loops ``L1`` or 
+``L2``.
+
+As a special case, if all memory accessing instructions in a loop have 
+``llvm.mem.parallel_loop_access`` metadata that refers to that loop, then the 
+loop has no loop carried memory dependences and is considered to be a parallel 
+loop.  
+
+Note that if not all memory access instructions have such metadata referring to 
+the loop, then the loop is considered not being trivially parallel. Additional 
+memory dependence analysis is required to make that determination.  As a fail 
+safe mechanism, this causes loops that were originally parallel to be considered 
+sequential (if optimization passes that are unaware of the parallel semantics 
+insert new memory instructions into the loop body).
 
 Example of a loop that is considered parallel due to its correct use of
 both ``llvm.loop`` and ``llvm.mem.parallel_loop_access``

Subject: [PATCH 107/906] [asan] properly instrument memory accesses that have
 small alignment (smaller than min(8,size)) by making two checks instead of
 one. This may slowdown some cases, e.g. long long on 32-bit or wide loads
 produced after loop unrolling. The benefit is higher sencitivity.

Subject: [PATCH 108/906] [mips][mips64r6] [ls][dw][lr] are not available in
 MIPS32r6/MIPS64r6

Summary:
Instead the system is required to provide some means of handling unaligned
load/store without special instructions. Options include full hardware
support, full trap-and-emulate, and hybrids such as hardware support within
a cache line and trap-and-emulate for multi-line accesses.

MipsSETargetLowering::allowsUnalignedMemoryAccesses() has been configured to
assume that unaligned accesses are 'fast' on the basis that I expect few
hardware implementations will opt for pure-software handling of unaligned
accesses. The ones that do handle it purely in software can override this.

mips64-load-store-left-right.ll has been merged into load-store-left-right.ll

The stricter testing revealed a Bits!=Bytes bug in passByValArg(). This has
been fixed and the variables renamed to clarify the units they hold.

Subject: [PATCH 110/906] [mips] Work around inconsistency in llvm-mc's
 placement of fixup markers

Summary:
Add a second fixup table to MipsAsmBackend::getFixupKindInfo() to correctly
position llvm-mc's fixup placeholders for big-endian.

See PR19836 for full details of the issue. To summarize, the fixup placeholders
do not account for endianness properly and the implementations of
getFixupKindInfo() for each target are measuring MCFixupKindInfo.TargetOffset
from different ends of the instruction encoding to compensate.

Subject: [PATCH 116/906] [RuntimeDyld] Remove relocation bounds check
 introduced in r208375 (MachO only).

We do all of our address arithmetic in 64-bit, and operations involving
logically negative 32-bit offsets (actually represented as unsigned 64 bit ints)
often overflow into higher bits. The overflow check could be preserved by
casting to uint32 at the callsite for applyRelocationValue, but this would
eliminate the value of the check.

The right way to handle overflow in relocations is to make relocation processing
target specific, and compute the values for RelocationEntry objects in the
appropriate types (32-bit for 32-bit targets, 64-bit for 64-bit targets). This
is coming as part of the cleanup I'm working on.

This fixes another i386 regression test.

Subject: [PATCH 117/906] Add the extracted constant offset using GEP

Fixed a TODO in r207783.

Add the extracted constant offset using GEP instead of ugly
ptrtoint+add+inttoptr. Using GEP simplifies future optimizations and makes IR
easier to understand.

Updated all affected tests, and added a new test in split-gep.ll to cover a
corner case where emitting uglygep is necessary.

Subject: [PATCH 120/906] Use alias linkage and visibility to decide tls access
 mode.

This matches both what we do for the non-thread case and what gcc does.

With this patch clang would match gcc's behaviour in

static __thread int a = 42;
extern __thread int b __attribute__((alias("a")));
int *f(void) { return &a; }
int *g(void) { return &b; }

if not for pr19843. Manually writing the IL does produce the same access modes.

It is also a step in the direction of fixing pr19844.

Subject: [PATCH 122/906] Fix and improve SCEV ComputeBackedgeTankCount.

This is a follow-up to r209358: PR19799: Indvars miscompile due to an
incorrect max backedge taken count from SCEV.

That fix was incomplete as pointed out by Arnold and Michael Z. The
code was also too confusing. It needed a careful rewrite with more
unit tests. This version will also happen to optimize more cases.

Subject: [PATCH 123/906] DebugInfo: Put concrete definitions referencing
 abstract definitions in the same scope as the abstract definition.

This seems like a simple cleanup/improved consistency, but also helps
lay the foundation to fix the bug mentioned in the test case: concrete
definitions preceeding any inlined usage aren't properly split into
concrete + abstract (because they're not known to need it until it's too
late).

Once we start deferring this choice until later, we won't have the
choice to put concrete definitions for inlined subroutines in a
different scope from concrete definitions for non-inlined subroutines
(since we won't know at time-of-construction which one it'll be). This
change brings those two cases into alignment ahead of that future
chaneg/fix.

Subject: [PATCH 128/906] DebugInfo: Generalize some tests to handle variations
 in attribute ordering.

In an effort to fix inlined debug info in situations where the out of
line definition of a function preceeds any inlined usage, the order in
which some attributes are added to subprogram DIEs may change. (in
essence, definition-necessary attributes like DW_AT_low_pc/high_pc will
be added immediately, but the names, types, and other features will be
delayed to module end where they may either be added to the subprogram
DIE or instead reference an abstract definition for those values)

These tests can be generalized to be resilient to this change. 5 or so
tests actually have to be incompatibly changed to cope with this
reordering and will go along with the change that affects the order.

Subject: [PATCH 129/906] ARM64: extract a 32-bit subreg when selecting an
 inreg extend

After the load/store refactoring, we were sometimes trying to feed a
GPR64 into a 32-bit register offset operand. This failed in
copyPhysReg.

Subject: [PATCH 130/906] Implement sext(C1 + C2*X) --> sext(C1) + sext(C2*X)
 and sext{C1,+,C2} --> sext(C1) + sext{0,+,C2} transformation in Scalar
 Evolution.

That helps SLP-vectorizer to recognize consecutive loads/stores.

Subject: [PATCH 132/906] AArch64/ARM64: remove AArch64 from tree prior to
 renaming ARM64.

I'm doing this in two phases for a better "git blame" record. This
commit removes the previous AArch64 backend and redirects all
functionality to ARM64. It also deduplicates test-lines and removes
orphaned AArch64 tests.

The next step will be "git mv ARM64 AArch64" and rewire most of the
tests.

Hopefully LLVM is still functional, though it would be even better if
no-one ever had to care because the rename happens straight
afterwards.

-//

-//
-//===----------------------------------------------------------------------===//
-// This describes the calling conventions for AArch64 architecture.
-//===----------------------------------------------------------------------===//
-
-
-// The AArch64 Procedure Call Standard is unfortunately specified at a slightly
-// higher level of abstraction than LLVM's target interface presents. In
-// particular, it refers (like other ABIs, in fact) directly to
-// structs. However, generic LLVM code takes the liberty of lowering structure
-// arguments to the component fields before we see them.
-//
-// As a result, the obvious direct map from LLVM IR to PCS concepts can't be
-// implemented, so the goals of this calling convention are, in decreasing
-// priority order:
-//     1. Expose *some* way to express the concepts required to implement the
-//        generic PCS from a front-end.
-//     2. Provide a sane ABI for pure LLVM.
-//     3. Follow the generic PCS as closely as is naturally possible.
-//
-// The suggested front-end implementation of PCS features is:
-//     * Integer, float and vector arguments of all sizes which end up in
-//       registers are passed and returned via the natural LLVM type.
-//     * Structure arguments with size <= 16 bytes are passed and returned in
-//       registers as similar integer or composite types. For example:
-//       [1 x i64], [2 x i64] or [1 x i128] (if alignment 16 needed).
-//     * HFAs in registers follow rules similar to small structs: appropriate
-//       composite types.
-//     * Structure arguments with size > 16 bytes are passed via a pointer,
-//       handled completely by the front-end.
-//     * Structure return values > 16 bytes via an sret pointer argument.
-//     * Other stack-based arguments (not large structs) are passed using byval
-//       pointers. Padding arguments are added beforehand to guarantee a large
-//       struct doesn't later use integer registers.
-//
-// N.b. this means that it is the front-end's responsibility (if it cares about
-// PCS compliance) to check whether enough registers are available for an
-// argument when deciding how to pass it.

-// Contains: ADD, ADDS, SUB, SUBS + aliases CMN, CMP, MOV
-
-// These instructions accept a 12-bit unsigned immediate, optionally shifted
-// left by 12 bits. Official assembly format specifies a 12 bit immediate with
-// one of "", "LSL #0", "LSL #12" supplementary operands.
-
-// There are surprisingly few ways to make this work with TableGen, so this
-// implementation has separate instructions for the "LSL #0" and "LSL #12"
-// variants.
-
-// If the MCInst retained a single combined immediate (which could be 0x123000,
-// for example) then both components (imm & shift) would have to be delegated to
-// a single assembly operand. This would entail a separate operand parser
-// (because the LSL would have to live in the same AArch64Operand as the
-// immediate to be accessible); assembly parsing is rather complex and
-// error-prone C++ code.
-//
-// By splitting the immediate, we can delegate handling this optional operand to
-// an InstAlias. Supporting functions to generate the correct MCInst are still
-// required, but these are essentially trivial and parsing can remain generic.
-//
-// Rejected plans with rationale:
-// ------------------------------
-//
-// In an ideal world you'de have two first class immediate operands (in
-// InOperandList, specifying imm12 and shift). Unfortunately this is not
-// selectable by any means I could discover.
-//
-// An Instruction with two MCOperands hidden behind a single entry in
-// InOperandList (expanded by ComplexPatterns and MIOperandInfo) was functional,
-// but required more C++ code to handle encoding/decoding. Parsing (the intended
-// main beneficiary) ended up equally complex because of the optional nature of
-// "LSL #0".
-//
-// Attempting to circumvent the need for a custom OperandParser above by giving
-// InstAliases without the "lsl #0" failed. add/sub could be accommodated but
-// the cmp/cmn aliases didn't use the MIOperandInfo to determine how operands
-// should be parsed: there was no way to accommodate an "lsl #12".

-// 1.1 Unsigned 12-bit immediate operands
-//===-------------------------------
-// The addressing mode for these instructions consists of an unsigned 12-bit
-// immediate which is scaled by the size of the memory access.
-//
-// We represent this in the MC layer by two operands:
-//     1. A base register.
-//     2. A 12-bit immediate: not multiplied by access size, so "LDR x0,[x0,#8]"
-//        would have '1' in this field.
-// This means that separate functions are needed for converting representations
-// which *are* aware of the intended access size.
-
-// Anything that creates an MCInst (Decoding, selection and AsmParsing) has to
-// know the access size via some means. An isolated operand does not have this
-// information unless told from here, which means we need separate tablegen
-// Operands for each access size. This multiclass takes care of instantiating
-// the correct template functions in the rest of the backend.

-//   3. Address-generation: A64Wrapper, (add BASE, OFFSET), ...

-// The biggest problem turns out to be the address-generation variable. At the
-// point of instantiation we need to produce two DAGs, one for the pattern and
-// one for the instruction. Doing this at the lowest level of classes doesn't

-//
-// Consider the simple uimm12 addressing mode, and the desire to match both (add
-// GPR64xsp:$Rn, uimm12:$Offset) and GPR64xsp:$Rn, particularly on the
-// instruction side. We'd need to insert either "GPR64xsp" and "uimm12" or
-// "GPR64xsp" and "0" into an unknown dag. !subst is not capable of this
-// operation, and PatFrags are for selection not output.
-//
-// As a result, the address-generation patterns are the final
-// instantiations. However, we do still need to vary the operand for the address

Subject: [PATCH 133/906] AArch64/ARM64: move ARM64 into AArch64's place

This commit starts with a "git mv ARM64 AArch64" and continues out
from there, renaming the C++ classes, intrinsics, and other
target-local objects for consistency.

"ARM64" test directories are also moved, and tests that began their
life in ARM64 use an arm64 triple, those from AArch64 use an aarch64
triple. Both should be equivalent though.

This finishes the AArch64 merge, and everyone should feel free to
continue committing as normal now.

Subject: [PATCH 134/906] CodeGen: Make MachineBasicBlock::back skip to the
 beginning of the last bundle.

This makes front/back symmetric with begin/end, avoiding some confusion.
Added instr_front/instr_back for the old behavior, corresponding to
instr_begin/instr_end. Audited all three in-tree users of back(), all
of them look like they don't want to look inside bundles.

Fixes an assertion (PR19815) when generating debug info on mips, where a
delay slot was bundled at the end of a branch.

shouldn't be used when objects can be the full 64-bits away.

This fixes MCJIT tests on Linux.

This extension point allows adding passes that perform peephole optimizations
similar to the instruction combiner. These passes will be inserted after
each instance of the instruction combiner pass.

Subject: [PATCH 142/906] Emit data or code export directives based on the
 type.

Currently we look at the Aliasee to decide what type of export
directive to use. It seems better to use the type of the alias
directly. This is similar to how we handle the alias having the
same address but other attributes (linkage, visibility) from the
aliasee.

With this patch it is now possible to do things like

target datalayout = "e-m:e-i64:64-f80:128-n8:16:32:64-S128"
target triple = "x86_64-pc-windows-msvc"
@foo = global [6 x i8] c"\B8*\00\00\00\C3", section ".text", align 16
@f = dllexport alias i32 (), [6 x i8]* @foo
!llvm.module.flags = !{!0}
!0 = metadata !{i32 6, metadata !"Linker Options", metadata !1}
!1 = metadata !{metadata !2, metadata !3}
!2 = metadata !{metadata !"/DEFAULTLIB:libcmt.lib"}
!3 = metadata !{metadata !"/DEFAULTLIB:oldnames.lib"}

Subject: [PATCH 144/906] DebugInfo: Fix inlining with #file directives a
 little harder

Seems my previous fix was insufficient - we were still not adding the
inlined function to the abstract scope list. Which meant it wasn't
flagged as inline, didn't have nested lexical scopes in the abstract
definition, and didn't have abstract variables - so the inlined variable
didn't reference an abstract variable, instead being described
completely inline.

Subject: [PATCH 146/906] tools: refactor COFFDumper symbol resolution logic

Make the use of the cache more transparent to the users.  There is no reason
that the cached entries really need to be passed along.  The overhead for doing
so is minimal: a single extra parameter.  This requires that some standalone
functions be brought into the COFFDumper class so that they may access the
cache.

Subject: [PATCH 148/906] tools: split out Win64EHDumper from COFFDumper

Move the implementation of the Win64 EH printer from the COFFDumper into its own
class.  This is in preparation for adding support to print ARM EH information.
The only real change here is in printUnwindInfo where we now lambda lift the
implicit this parameter for the resolveFunction.  Also setup the printing to
handle ARM.  This now has set the stage to introduce ARM EH printing.

Subject: [PATCH 149/906] tools: avoid use of std::function

Remove the use of the std::function and replace the capturing lambda with a
non-capturing one, opting to pass the user data down to the context.  This is
needed as std::function is not yet available on all hosted platforms (it
requires RTTI, which breaks on Windows).

Thanks to Nico Rieck for pointing this out!

Subject: [PATCH 154/906] DebugInfo: Test linkonce-odr functions under LTO.

This was previously regressed/broken by r192749 (reverted due to this
issue in r192938) and I was about to break it again by accident with
some more invasive changes that deal with the subprogram lists. So to
avoid that and further issues - here's a test.

It's a pretty basic test - in both r192749 and my impending case, this
test would crash, but checking the basics (that we put a subprogram in
just one of the two CUs) seems like a good start.

We still get this wrong in weird ways if the linkonce-odr function
happens to not be identical in the metadata (because it's defined in two
different files (hence the # line directives in this test), etc) even
though it meets the language requirements (identical token stream) for
such a thing. That results in two subprogram DIEs, but only one of them
gets the parameter and high/low pc information, etc. We probably need to
use the DIRef infrastructure to deduplicate functions as we do types to
address this issue - or perhaps teach the BC linker to remove the
duplicate entries in subprogram lists?

Subject: [PATCH 155/906] Make the LoopRotate pass's maximum header size
 configurable both programmatically and via the command line, mirroring
 similar functionality in LoopUnroll.  In situations where clients used custom
 unrolling thresholds, their intent could previously be foiled by LoopRotate
 having a hardcoded threshold.

Subject: [PATCH 156/906] [AArch64] Add a regression test for the load store
 optimizer.

We have a couple of regression tests for load/store pairing, but (to my knowledge) there are no regression tests for the load/store + add/sub folding.

As a first step towards increased test coverage of this area, this commit adds a test for one instance of a load + add to pre-indexed load transformation.

Subject: [PATCH 164/906] AArch64: simplify calling conventions slightly.

We can eliminate the custom C++ code in favour of some TableGen to
check the same things. Functionality should be identical, except for a
buffer overrun that was present in the C++ code and meant webkit
failed if any small argument needed to be passed on the stack.

Subject: [PATCH 165/906] AArch64: force i1 to be zero-extended at an ABI
 boundary.

This commit is debatable. There are two possible approaches, neither
of which is really satisfactory:

1. Use "@foo(i1 zeroext)" to mean an extension to 32-bits on Darwin,
   and 8 bits otherwise.
2. Redefine "@foo(i1)" to mean that the i1 is extended by the caller
   to 8 bits. This goes against the spirit of "zeroext" I think, but
   it's a bit of a vague construct anyway (by definition you're going
   to extend to the amount required by the ABI, that's why it's the
   ABI!).

This implements option 2. The DAG machinery really isn't setup for the
first (there's a fairly strong assumption that "zeroext" goes to at
least the smallest register size), and even if it was the resulting
DAG looks like it would be inferior in many cases.

Theoretically we could add AssertZext nodes in the consumers of
ABI-passed values too now, but this actually seems to make the code
worse in practice by making truncation proceed in two steps. The code
produced is equally valid if we continue to assume only the low bit is
defined.

Should fix PR19850

Subject: [PATCH 169/906] Convert some X86 blendv* intrinsics into IR.

Summary:
Implemented an InstCombine transformation that takes a blendv* intrinsic
call and translates it into an IR select, if the mask is constant.

This will eventually get lowered into blends with immediates if possible,
or pblendvb (with an option to further optimize if we can transform the
pblendvb into a blend+immediate instruction, depending on the selector).
It will also enable optimizations by the IR passes, which give up on
sight of the intrinsic.

Both the transformation and the lowering of its result to asm got shiny
new tests.

The transformation is a bit convoluted because of blendvp[sd]'s
definition:

Its mask is a floating point value! This forces us to convert it and get
the highest bit. I suppose this happened because the mask has type
__m128 in Intel's intrinsic and v4sf (for blendps) in gcc's builtin.

I will send an email to llvm-dev to discuss if we want to change this or
not.

These are tested by test/CodeGen/Generic, so we should probably know
how to deal with them. Fortunately generic code does it if asked.

Subject: [PATCH 173/906] ARM: teach AAPCS-VFP to deal with Cortex-M4.

Cortex-M4 only has single-precision floating point support, so any LLVM
"double" type will have been split into 2 i32s by now. Fortunately, the
consecutive-register framework turns out to be precisely what's needed to
reconstruct the double and follow AAPCS-VFP correctly!

Subject: [PATCH 174/906] AArch64: implement copies to/from NZCV as a last
 ditch effort.

A test in test/Generic creates a DAG where the NZCV output of an ADCS is used
by multiple nodes. This makes LLVM want to save a copy of NZCV for later, which
it couldn't do before.

This should be the last fix required for the aarch64 buildbot.

splats followed by a vector add or subtract.  This operation is
represented by a VADD_SPLAT in the selection DAG.  Prior to this
patch, it was possible for the VADD_SPLAT to be assigned the wrong
data type, causing incorrect code generation.  This patch corrects the
problem.

Specifically, the code previously assigned the value type of the
BUILD_VECTOR node to the newly generated VADD_SPLAT node.  This is
correct much of the time, but not always.  The problem is that the
call to isConstantSplat() may return a SplatBitSize that is not the
same as the number of bits in the original element vector type.  The
correct type to assign is a vector type with the same element bit size
as SplatBitSize.

The included test case shows an example of this, where the
BUILD_VECTOR node has a type of v16i8.  The vector to be built is {0,
16, 0, 16, 0, 16, 0, 16, 0, 16, 0, 16, 0, 16, 0, 16}.  isConstantSplat
detects that we can generate a splat of 16 for type v8i16, which is
the type we must assign to the VADD_SPLAT node.  If we do not, we
generate a vspltisb of 8 and a vaddubm, which generates the incorrect
result {16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16,
16}.  The correct code generation is a vspltish of 8 and a vadduhm.

This patch also corrected code generation for
CodeGen/PowerPC/2008-07-10-SplatMiscompile.ll, which had been marked
as an XFAIL, so we can remove the XFAIL from the test case.

Subject: [PATCH 183/906] DebugInfo: Fix argument ordering in test by adding
 argument numbering.

This old test didn't have the argument numbering that's now squirelled
away in the high bits of the line number in the DW_TAG_arg_variable
metadata.

Add the numbering and update the test to ensure arguments are in-order.

Subject: [PATCH 184/906] Distribute sext/zext to the operands of and/or/xor

This is an enhancement to SeparateConstOffsetFromGEP. With this patch, we can
extract a constant offset from "s/zext and/or/xor A, B".

Added a new test @ext_or to verify this enhancement.

Refactoring the code, I also extracted some common logic to function
Distributable.

Subject: [PATCH 187/906] DebugInfo: Lazily attach definition attributes to
 definitions.

This is a precursor to fixing inlined debug info where the concrete,
out-of-line definition may preceed any inlined usage. To cope with this,
the attributes that may appear on the concrete definition or the
abstract definition are delayed until the end of the module. Then, if an
abstract definition was created, it is referenced (and no other
attributes are added to the out-of-line definition), otherwise the
attributes are added directly to the out-of-line definition.

In a couple of cases this causes not just reordering of attributes, but
reordering of types. When the creation of the attribute is delayed, if
that creation would create a type (such as for a DW_AT_type attribute)
then other top level DIEs may've been constructed during the delay,
causing the referenced type to be created and added after those
intervening DIEs. In the extreme case, in cross-cu-inlining.ll, this
actually causes the DW_TAG_basic_type for "int" to move from one CU to
another.

From 254d093f991287bea06e47c27ef2e14db36b1c59 Mon Sep 17 00:00:00 2001

Subject: [PATCH 188/906] DebugInfo: Lazily construct subprogram definition
 DIEs.

A further step to correctly emitting concrete out of line definitions
preceeding inlined instances of the same program.

To do this, emission of subprograms must be delayed until required since
we don't know which (abstract only (if there's no out of line
definition), concrete only (if there are no inlined instances), or both)
DIEs are required at the start of the module.

To reduce the test churn in the following commit that actually fixes the
bug, this commit introduces the lazy DIE construction and cleans up test
cases that are impacted by the changes in the resulting DIE ordering.

Subject: [PATCH 190/906] DebugInfo: Create abstract function definitions even
 when concrete definitions preceed inline definitions.

After much puppetry, here's the major piece of the work to ensure that
even when a concrete definition preceeds all inline definitions, an
abstract definition is still created and referenced from both concrete
and inline definitions.

Variables are still broken in this case (see comment in
dbg-value-inlined-parameter.ll test case) and will be addressed in
follow up work.

Subject: [PATCH 191/906] [mips] Optimize long branch for MIPS64 by removing
 %higher and %highest. %higher and %highest can have non-zero values only for
 offsets greater than 2GB, which is highly unlikely, if not impossible when
 compiling a single function. This makes long branch for MIPS64 3 instructions
 smaller.

Subject: [PATCH 193/906] DebugInfo: partially revert cleanup committed in
 r209680

I'm not sure exactly where/how we end up with an abstract DbgVariable
with a null DIE, but we do... looking into it & will add a test and/or
fix when I figure it out.

Currently shows up in selfhost or compiler-rt builds.

Subject: [PATCH 197/906] Don't pre-populate the set of keys in the map with
 variable locations history.

Current implementation of calculateDbgValueHistory already creates the
keys in the expected order (user variables are listed in order of appearance),
and should do so later by contract.

No functionality change.

Subject: [PATCH 198/906] remove constant terms

The delinearization is needed only to remove the non linearity induced by
expressions involving multiplications of parameters and induction variables.
There is no problem in dealing with constant times parameters, or constant times
an induction variable.

For this reason, the current patch discards all constant terms and multipliers
before running the delinearization algorithm on the terms. The only thing
remaining in the term expressions are parameters and multiply expressions of
parameters: these simplified term expressions are passed to the array shape
recognizer that will not recognize constant dimensions anymore: these will be
recognized as different strides in parametric subscripts.

The only important special case of a constant dimension is the size of elements.
Instead of relying on the delinearization to infer the size of an element,
compute the element size from the base address type. This is a much more precise
way of computing the element size than before, as we would have mixed together
the size of an element with the strides of the innermost dimension.

Subject: [PATCH 199/906] remove BasePointer before delinearizing

No functional change is intended: instead of relying on the delinearization to
come up with the base pointer as a remainder of the divisions in the
delinearization, we just compute it from the array access and use that value.
We substract the base pointer from the SCEV to be delinearized and that
simplifies the work of the delinearizer.

Subject: [PATCH 200/906] do not use the GCD to compute the delinearization
 strides

We do not need to compute the GCD anymore after we removed the constant
coefficients from the terms: the terms are now all parametric expressions and
there is no need to recognize constant terms that divide only a subset of the
terms. We only rely on the size of the terms, i.e., the number of operands in
the multiply expressions, to sort the terms and recognize the parametric
dimensions.

Subject: [PATCH 201/906] avoid type mismatch when building SCEVs

This is a corner case I have stumbled upon when dealing with ARM64 type
conversions. I was not able to extract a testcase for the community codebase to
fail on. The patch conservatively discards a division that would have ended up
in an ICE due to a type mismatch when building a multiply expression. I have
also added code to a place that builds add expressions and in which we should be
careful not to pass in operands of different types.

Subject: [PATCH 203/906] Change representation of instruction ranges where
 variable is accessible.

Use more straightforward way to represent the set of instruction
ranges where the location of a user variable is defined - vector of pairs
of instructions (defining start/end of each range),
instead of a flattened vector of instructions where some instructions
are supposed to start the range, and the rest are supposed to "clobber" it.

Simplify the code which generates actual .debug_loc entries.

No functionality change.

Subject: [PATCH 209/906] Revert "[PPC] Use alias symbols in address
 computation."

This reverts commit r209638 because it broke self-hosting on ppc64/Linux. (the
Clang-compiled TableGen would segfault because it jumped to an invalid address
from within _ZNK4llvm17ManagedStaticBase21RegisterManagedStaticEPFPvvEPFvS1_E
(which is within the command-line parameter registration process)).

Subject: [PATCH 210/906] InstCombine: Improvement to check if signed addition
 overflows.

This patch implements two things:

1. If we know one number is positive and another is negative, we return true as
   signed addition of two opposite signed numbers will never overflow.

2. Implemented TODO : If one of the operands only has one non-zero bit, and if
   the other operand has a known-zero bit in a more significant place than it
   (not including the sign bit) the ripple may go up to and fill the zero, but
   won't change the sign. e.x -  (x & ~4) + 1

We make sure that we are ignoring 0 at MSB.

Patch by Suyog Sarda.

Subject: [PATCH 211/906] Revert "[DAGCombiner] Split up an indexed load if
 only the base pointer value is live"

This reverts r208640 (I've just XFAILed the test) because it broke ppc64/Linux
self-hosting. Because nearly every regression test triggers a segfault, I hope
this will be easy to fix.

Subject: [PATCH 212/906] Add support for combining GEPs across PHI nodes

Currently LLVM will generally merge GEPs. This allows backends to use more
complex addressing modes. In some cases this is not happening because there
is PHI inbetween the two GEPs:

  GEP1--\
        |-->PHI1-->GEP3
  GEP2--/

This patch checks to see if GEP1 and GEP2 are similiar enough that they can be
cloned (GEP12) in GEP3's BB, allowing GEP->GEP merging (GEP123):

  GEP1--\                     --\                           --\
        |-->PHI1-->GEP3  ==>    |-->PHI2->GEP12->GEP3 == >    |-->PHI2->GEP123
  GEP2--/                     --/                           --/

This also breaks certain use chains that are preventing GEP->GEP merges that the
the existing instcombine would merge otherwise.

Tests included.

Subject: [PATCH 213/906] [pr19844] Add thread local mode to aliases.

This matches gcc's behavior. It also seems natural given that aliases
contain other properties that govern how it is accessed (linkage,
visibility, dll storage).

Clang still has to be updated to expose this feature to C.

Subject: [PATCH 214/906] Fix standard integer definitions for MSVC in
 DataTypes.h

Previously, DataTypes.h would #define a variety of symbols any time
they weren't already defined.  However, some versions of Visual
Studio do provide the appropriate headers, so if those headers are
included after DataTypes.h, it can lead to macro redefinition
warnings.

The fix is to include the appropriate headers if they exist, and
only #define the symbols if the required header does not exist.

Patch by Zachary Turner!

---

The big change here is that we no longer have our own stdint.h
typedefs because now all supported toolchains have stdint.h.
Hooray!

Subject: [PATCH 215/906] Revert "InstCombine: Improvement to check if signed
 addition overflows."

This reverts commit r209746.

It looks it is causing a crash while building libcxx. I am trying to get a
reduced testcase.

Add a function to combine two 32-bit integers into a 64-bit integer.
There are no calls to this function yet, although a subsequent change
will add some in LLDB.

Subject: [PATCH 223/906] [ASan] Use llvm.global_ctors to insert init-order
 checking calls into ASan runtime.

Don't assume that dynamically initialized globals are all initialized from
_GLOBAL__<module_name>I_ function. Instead, scan the llvm.global_ctors and
insert poison/unpoison calls to each function there.

Patch by Nico Weber!

Subject: [PATCH 226/906] [x86] Fold extract_vector_elt of a load into the
 Load's address computation.

An address only use of an extract element of a load can be simplified to a
load. Without this the result of the extract element is spilled to the
stack so that an address is available.

Subject: [PATCH 227/906] [ASan] Hoist blacklisting globals from init-order
 checking to Clang.

Clang knows about the sanitizer blacklist and it makes no sense to
add global to the list of llvm.asan.dynamically_initialized_globals if it
will be blacklisted in the instrumentation pass anyway. Instead, we should
do as much blacklisting as possible (if not all) in the frontend.

Subject: [PATCH 230/906] LCSSA should be performed on the outermost affected
 loop while unrolling loop.

During loop-unroll, loop exits from the current loop may end up in in different
outer loop. This requires to re-form LCSSA recursively for one level down from
the outer most loop where loop exits are landed during unroll. This fixes PR18861.

Differential Revision: http://reviews.llvm.org/D2976

Subject: [PATCH 238/906] [PPC] Use alias symbols in address computation.

This seems to match what gcc does for ppc and what every other llvm
backend does.

This is a fixed version of r209638. The difference is to avoid any change
in behavior for functions. The logic for using constant pools for function
addresseses is spread over a few places and we have to keep them in sync.

Subject: [PATCH 246/906] Add support for combining GEPs across PHI nodes

Currently LLVM will generally merge GEPs. This allows backends to use more
complex addressing modes. In some cases this is not happening because there
is PHI inbetween the two GEPs:

  GEP1--\
        |-->PHI1-->GEP3
  GEP2--/

This patch checks to see if GEP1 and GEP2 are similiar enough that they can be
cloned (GEP12) in GEP3's BB, allowing GEP->GEP merging (GEP123):

  GEP1--\                     --\                           --\
        |-->PHI1-->GEP3  ==>    |-->PHI2->GEP12->GEP3 == >    |-->PHI2->GEP123
  GEP2--/                     --/                           --/

This also breaks certain use chains that are preventing GEP->GEP merges that the
the existing instcombine would merge otherwise.

Tests included.

Subject: [PATCH 247/906] Added tests for shufflevector lowering to blend
 instrs.

These tests ensure that a change I will propose in clang works as
expected.

Summary:
Added tests for the generation of blend+immediate instructions from a
shufflevector.
These tests were proposed along with a patch that was dropped. I'm
committing the tests anyway to protect against possible regressions in
codegen.

Subject: [PATCH 248/906] LoopVectorizer: Add a check that the backedge taken
 count + 1 does not overflow

The loop vectorizer instantiates be-taken-count + 1 as the loop iteration count.
If this expression overflows the generated code was invalid.

In case of overflow the code now jumps to the scalar loop.

Fixes PR17288.

 combining GEPs across PHI nodes. The code was computing the Idxs from the

Subject: [PATCH 252/906] [X86] Auto-upgrade AVX1 vbroadcast intrinsics

They are replaced with the same IR that is generated for the
vector-initializers in avxintrin.h.

The test verifies that we get back the original instruction.  I haven't seen
this approach to be used in other auto-upgrade tests (i.e. llc + FileCheck)
but I think it's the most direct way to test this case.  I believe this should
work because llc upgrades calls during parsing.  (Other tests mostly check
that assembling and disassembling yields the upgraded IR.)

Subject: [PATCH 253/906] [X86] Remove AVX1 vbroadcast intrinsics

The corresponding CFE patch replaces these intrinsics with vector initializers
in avxintrin.h.  This patch removes the LLVM intrinsics from the backend.

We now stop lowering at X86ISD::VBROADCAST custom node rather than lowering
that further to the intrinsics.

The patch only changes VBROADCASTS* and leaves VBROADCAST[FI]128 to continue
to use intrinsics.  As explained in the CFE patch, the reason is that we
currently don't generate as good code for them without the intrinsics.

CodeGen/X86/avx-vbroadcast.ll already provides coverage for this change.  It
checks that for a series of insertelements we generate the appropriate
vbroadcast instruction.

Also verified that there was no assembly change in the test-suite before and
after this patch.

Subject: [PATCH 258/906] Allow vectorization of intrinsics such as powi,cttz
 and ctlz in Loop and SLP Vectorizer.

This patch adds support to vectorize intrinsics such as powi, cttz and ctlz in Vectorizer. These intrinsics are different from other
intrinsics as second argument to these function must be same in order to vectorize them and it should be represented as a scalar.

Subject: [PATCH 261/906] ARM & AArch64: make use of common cmpxchg idioms
 after expansion

The C and C++ semantics for compare_exchange require it to return a bool
indicating success. This gets mapped to LLVM IR which follows each cmpxchg with
an icmp of the value loaded against the desired value.

When lowered to ldxr/stxr loops, this extra comparison is redundant: its
results are implicit in the control-flow of the function.

This commit makes two changes: it replaces that icmp with appropriate PHI
nodes, and then makes sure earlyCSE is called after expansion to actually make
use of the opportunities revealed.

I've also added -{arm,aarch64}-enable-atomic-tidy options, so that
existing fragile tests aren't perturbed too much by the change. Many
of them either rely on undef/unreachable too pervasively to be
restored to something well-defined (particularly while making sure
they test the same obscure assert from many years ago), or depend on a
particular CFG shape, which is disrupted by SimplifyCFG.

Subject: [PATCH 264/906] ARM: use AAPCS-style prologues for embedded MachO.

Darwin prologues save their GPRs in two stages: a narrow push of r0-r7 & lr,
followed by a wide push of the remaining registers if there are any. AAPCS uses
a single push.w instruction.

It turns out that, on average, enough registers get pushed that code is smaller
in the AAPCS prologue, which is a nice property for M-class programmers. They
also have other options available for back-traces, so can hopefully deal with
the fact that FP & LR aren't adjacent in memory.

 operations

Unordered is strictly weaker than monotonic, so if the latter doesn't have any
barriers then the former certainly shouldn't.

Subject: [PATCH 269/906] Fix MIPS exception personality encoding.

For MIPS, we have to encode the personality routine with
an indirect pointer to absptr; otherwise, some link warning
warning will be raised, and the program might crash in some
early MIPS Android device.

Subject: [PATCH 275/906] Separate the check for blend shuffle_vector masks

Summary:
Separate the check for blend shuffle_vector masks into isBlendMask.
This function will also be used to check if a vector shuffle is legal. No
change in functionality was intended, but we ended up improving codegen on
two tests, which were being (more) optimized only if the resulting shuffle
was legal.

Subject: [PATCH 278/906] Convert a vselect into a concat_vector if possible

Summary:
If both vector args to vselect are concat_vectors and the condition is
constant and picks half a vector from each argument, convert the vselect
into a concat_vectors.

Added a test.

The ConvertSelectToConcatVector is assuming it doesn't get vselects with
arguments of, for example, <undef, undef, true, true>. Those get taken
care of in the checks above its call.

Subject: [PATCH 279/906] [X86] Add two combine rules to simplify dag nodes
 introduced during type legalization when promoting nodes with illegal vector
 type.

This patch teaches the backend how to simplify/canonicalize dag node
sequences normally introduced by the backend when promoting certain dag nodes
with illegal vector type.

This patch adds two new combine rules:
1) fold (shuffle (bitcast (BINOP A, B)), Undef, <Mask>) ->
        (shuffle (BINOP (bitcast A), (bitcast B)), Undef, <Mask>)

2) fold (BINOP (shuffle (A, Undef, <Mask>)), (shuffle (B, Undef, <Mask>))) ->
        (shuffle (BINOP A, B), Undef, <Mask>).

Both rules are only triggered on the type-legalized DAG.
In particular, rule 1. is a target specific combine rule that attempts
to sink a bitconvert into the operands of a binary operation.
Rule 2. is a target independet rule that attempts to move a shuffle
immediately after a binary operation.

Subject: [PATCH 280/906] Have the TLOF creation take a Triple rather than
 needing a subtarget.

There is no std::error_code::success, so this removes much of the noise
in transitioning to std::error_code.

Subject: [PATCH 292/906] [yaml2obj] Add new command line option `-docnum`.

Input YAML file might contain multiple object file definitions.
New option `-docnum` allows to specify an ordinal number (starting from 1)
of definition used for an object file generation.

Patch reviewed by Sean Silva.

Subject: [PATCH 295/906] [Reassociate] Similar to "X + -X" -> "0", added code
 to handle "X + ~X" -> "-1".

Handle "X + ~X" -> "-1" in the function Value *Reassociate::OptimizeAdd(Instruction *I, SmallVectorImpl<ValueEntry> &Ops);
This patch implements:
TODO: We could handle "X + ~X" -> "-1" if we wanted, since "-X = ~X+1".

Patch by Rahul Jain!

Subject: [PATCH 298/906] [SelectionDAG] Force cycle detection in
 AssignTopologicalOrder before aborting

DAG cycle detection is only enabled with ENABLE_EXPENSIVE_CHECKS.  However we
can run it just before we would crash in order to provide more informative
diagnostics.

Now in addition to the "Overran sorted position" message we also get the Node
printed if a cycle was detected.

Tested by building several configs: Debug+Assert, Debug+Assert+Check (this is
ENABLE_EXPENSIVE_CHECKS), Release+Assert and Release.  Also tried that the
AssignTopologicalOrder assert produces the expected results.

Subject: [PATCH 303/906] DebugInfo: Assert that DbgVariables have associated
 DIEs

This was previously committed in r209680 and reverted in r209683 after
it caused sanitizer builds to crash.

The issue seems to be that the DebugLoc associated with dbg.value IR
intrinsics isn't necessarily accurate. Instead, we duplicate the
DIVariables and add an InlinedAt field to them to record their
location.

We were using this InlinedAt field to compute the LexicalScope for the
variable, but not using it in the abstract DbgVariable construction and
mapping. This resulted in a formal parameter to the current concrete
function, correctly having no InlinedAt information, but incorrectly
having a DebugLoc that described an inlined location within the
function... thus an abstract DbgVariable was created for the variable,
but its DIE was never constructed (since the LexicalScope had no such
variable). This DbgVariable was silently ignored (by testing for a
non-null DIE on the abstract DbgVariable).

So, fix this by using the right scoping information when constructing
abstract DbgVariables.

In the long run, I suspect we want to undo the work that added this
second kind of location tracking and fix the places where the DebugLoc
propagation on the dbg.value intrinsic fails. This will shrink debug
info (by not duplicating DIVariables), make it more efficient (by not
having to construct new DIVariable metadata nodes to try to map back to
a single variable), and benefit all instructions.

But perhaps there are insurmountable issues with DebugLoc quality that
I'm unaware of... I just don't know how we can't /just keep the DebugLoc
from the dbg.declare to the dbg.values and never get this wrong/.

Some history context:

Subject: [PATCH 307/906] Support: add Windows ARM EH data structures

Introduce the support structures necessary to deal with the Windows ARM EH data.
These definitions are extremely aggressive about assertions to aid future use
for generation of the entries and subsequent decoding.

The names for the various fields are meant to reflect the names used by the
Visual Studio toolchain to aid communication.

Due to the complexity in reading a few of the values, there are a couple of
additional utility functions to decode the information.

In general, there are two ways to encode the unwinding information:
- packed, which places the data inline into the
  _IMAGE_ARM_RUNTIME_FUNCTION_ENTRY structure.
- unpacked, which places the data into auxiliary structures placed into the
  .xdata section.

The set of structures allow reading of data in either encoding, with the minor
caveat that epilogue scopes need to be decoded manually by constructing the
structure from the data returned by the RuntimeFunction structure.

These definitions are meant for read-only access at the current point as the
first use of them will be to decode the exception information.

+/// C : 1-bit flag indicating whether the function includes extra instructions

Subject: [PATCH 308/906] Support: add 6-parameter format

Since we cannot yet use variadic templates, add a specialisation for
6-parameters to format.  This is motivated by a need for the additional
parameter for formatting information for an unwind decoder for Windows on ARM.

Subject: [PATCH 310/906] GraphWriter: detect graph viewer programs at runtime

Replace the crufty build-time configure checks for program paths with
equivalent runtime logic.

This lets users install graphing tools as needed without having to reconfigure
and rebuild LLVM, while eliminating a long chain of inappropriate compile
dependencies that included GUI programs and the windowing system.

Additional features:

 * Support the OS X 'open' command to view graphs generated by any of the
   Graphviz utilities. This is an alternative to the Graphviz OS X UI which is
   no longer available on Mountain Lion.

 * Produce informative log output upon failure to indicate which programs can
   be installed to view graphs.

Ping me if this doesn't work for your particular environment.

Subject: [PATCH 314/906] Added inst combine tarnsform for (1 << X) & C
 pattrens where C is (some PowerOf2 - 1)

This patch can handles following cases from http://nondot.org/sabre/LLVMNotes/InstCombine.txt
  "((1 << X) & 7) == 0" ==> "X > 2"
  "((1 << X) & 7) != 0" ==> "X < 3".

Subject: [PATCH 315/906] [AArch64] Add some more regression tests for load
 pre-index update folding in the load/store optimizer.

Add tests for the following transform:

 add x8, x8, #16
  ...
 ldr X, [x8]
  ->
 ldr X, [x8, #16]!

with X being either w0, x0, s0, d0 or q0.

Subject: [PATCH 320/906] Add the nsw flag when we detect that an add will not
 signed overflow.

We already had a function for checking this, we were just using it only in
specialized cases.

Subject: [PATCH 321/906] [X86] Fix checked arithmetic for i8 on X86.

When lowering a ISD::BRCOND into a test+branch, make sure that we
always use the correct condition code to emit the test operation.

This fixes PR19858: "i8 checked mul is wrong on x86".

Patch by Keno Fisher!

Subject: [PATCH 323/906] Remove sanitizer blacklist from ASan/TSan/MSan
 function passes.

Instrumentation passes now use attributes
address_safety/thread_safety/memory_safety which are added by Clang frontend.
Clang parses the blacklist file and adds the attributes accordingly.

Currently blacklist is still used in ASan module pass to disable instrumentation
for certain global variables. We should fix this as well by collecting the
set of globals we're going to instrument in Clang and passing it to ASan
in metadata (as we already do for dynamically-initialized globals and init-order
checking).

This change also removes -tsan-blacklist and -msan-blacklist LLVM commandline
flags in favor of -fsanitize-blacklist= Clang flag.

Subject: [PATCH 326/906] Revert "Add the nsw flag when we detect that an add
 will not signed overflow."

This reverts commit r210029.

It was not correctly handling cases where LHS and RHS had multiple but different
sign bits.

Subject: [PATCH 328/906] Add back commit r210029.

The code was actually correct. Sorry for the confusion. I have expanded the
comment saying why the analysis is valid to avoid me misunderstaning it
again in the future.

Subject: [PATCH 329/906] Allow alias to point to an arbitrary ConstantExpr.

This  patch changes GlobalAlias to point to an arbitrary ConstantExpr and it is
up to MC (or the system assembler) to decide if that expression is valid or not.

This reduces our ability to diagnose invalid uses and how early we can spot
them, but it also lets us do things like

@test5 = alias inttoptr(i32 sub (i32 ptrtoint (i32* @test2 to i32),
                                 i32 ptrtoint (i32* @bar to i32)) to i32*)

An important implication of this patch is that the notion of aliased global
doesn't exist any more. The alias has to encode the information needed to
access it in its metadata (linkage, visibility, type, etc).

Another consequence to notice is that getSection has to return a "const char *".
It could return a NullTerminatedStringRef if there was such a thing, but when
that was proposed the decision was to just uses "const char*" for that.

Subject: [PATCH 339/906] AArch64: mark small types (i1, i8, i16) as promoted

This means the output of LowerFormalArguments returns a lowered
SDValue with the correct type (expected in SelectionDAGBuilder).
Without this, an assertion under a DEBUG macro triggers when those
types are passed on the stack.

Subject: [PATCH 342/906] [AArch64] Add regression tests for the load/store
 optimizer which cover post-index update folding with sub rather than add.

The tests check that the following transform happens:

  (ldr|str) X, [x20]
   ...
  sub x20, x20, #16
   ->
  (ldr|str) X, [x20], #-16

with X being either w0, x0, s0, d0 or q0.

Subject: [PATCH 351/906] Calculate dead instructions when a live interval is
 created.

This gets us closer to being able to remove LiveVariables entirely which is where dead instructions are currently tagged as such.

Subject: [PATCH 353/906] DebugInfo: Partial revert r209984 due to more cases
 where abstract DbgVariables do not have associated DIEs.

Along with a test case to demonstrate that due to inlining order there
are cases where abstract variable DIEs are not constructed since the
abstract subprogram was built due to a previous inlining that optimized
away those variables. This produces incorrect debug info (the 'missing'
abstract variable causes the inlined instance of that variable to be
emitted with a full description (name, line, file) rather than
referencing the abstract origin), but this commit at least ensures that
it doesn't crash...

Subject: [PATCH 354/906] config.h: fix layering and don't duplicate
 definitions

Also correct the llvm-config.h header guard so it doesn't depend on 'CONFIG_H'
which is commonly defined in external projects and caused trouble for
embedders.

In future llvm/Config/llvm-config.h will be installed, but not
the private llvm/Config/config.h header.

Avoid changing behaviour for everyone who's used to the traditional ghostview
UI, especially since it knows how to stay in the foreground unlike xdg-open.

Subject: [PATCH 358/906] docs: Remove documentation for legacy PGO options

Late last year r191835 removed a largely unmaintained legacy PGO
infrastructure, but some of the docs were missed. Since these docs are
for things that don't actually exist anymore, they should be removed.

Subject: [PATCH 359/906] Move GenericScheduler and PostGenericScheduler into a
 header.

These were not exposed previously because I didn't want out-of-tree
targets to be too dependent on their internals. They can be reused for
a very wide variety of processors with casual scheduling needs without
exposing the classes by instead using hooks defined in
MachineSchedPolicy (we can add more if needed). When targets are more
aggressively tuned or want to provide custom heuristics, they can
define their own MachineSchedStrategy. I tend to think this is better
once you start customizing heuristics because you can copy over only
what you need. I don't think that layering heuristics generally works
well.

However, Arch64 targets now want to reuse the Generic scheduling logic
but also provide extensions. I don't see much harm in exposing the
Generic scheduling classes with a major caveat: these scheduling
strategies may change in the future without validating performance on
less mainstream processors. If you want to be immune from changes,
just define your own MachineSchedStrategy.

Subject: [PATCH 360/906] Add a subtarget hook: enablePostMachineScheduler.

As requested by AArch64 subtargets.

Note that this will have no effect until the
AArch64 target actually enables the pass like this:
substitutePass(&PostRASchedulerID, &PostMachineSchedulerID);

As soon as armv7 switches over, PostMachineScheduler will become the
default postRA scheduler, so this won't be necessary any more.
Targets using the old postRA schedule would then do:
substitutePass(&PostMachineSchedulerID, &PostRASchedulerID);

Subject: [PATCH 361/906] Fix a use of uninitialized value. OldCC is set when
 IsCmpZero || IsSwapped and read when ShouldUpdateCC || IsSwapped, and
 ShouldUpdateCC is independent. Fixes PR19932, but no test since I wasn't able
 to get any symptoms to appear, not even with valgrind and the testcase from
 the PR. It's clear what happened from inspection of the code.

Subject: [PATCH 365/906]  InstCombine: Improvement to check if signed addition
 overflows.

This patch implements two things:

1. If we know one number is positive and another is negative, we return true as
    signed addition of two opposite signed numbers will never overflow.

2. Implemented TODO : If one of the operands only has one non-zero bit, and if
    the other operand has a known-zero bit in a more significant place than it
    (not including the sign bit) the ripple may go up to and fill the zero, but
    won't change the sign. e.x -  (x & ~4) + 1

We make sure that we are ignoring 0 at MSB.

Subject: [PATCH 366/906] Support: add additional comment for ARM EH structure

Replicate the fact that ARM::WinEH::RuntimeFunction purposefully does not merge
functions to accommodate raw data access use cases in tools such as readobj.
Pointed out by Renato during post-commit review.

No functional change.

Subject: [PATCH 367/906] Support: style/documentation cleanup for format

This is purely a documentation/whitespace cleanup for the format support
functions.

The current style does not duplicate the function/class names in the
documentation; conform to this style.

Additionally, there was a large amount of duplication of comments that added no
real value.  Use block comments for the related sets of functions which are used
for type deduction and parameter container classes.

No functional change.

Subject: [PATCH 369/906] tools: initial implementation of WoA EH decoding

Add support to llvm-readobj to decode Windows ARM Exception Handling data.  This
uses the previously added datastructures to decode the information into a format
that can be used by tests.  This is a necessary step to add support for emitting
Windows on ARM exception handling information.

A fair amount of formatting inspiration is drawn from the Win64 EH printer as
well as the ARM EHABI printer.  This allows for a reasonably thorough look into
the encoded data.

Subject: [PATCH 373/906] Two small enhancements for the JIT.

When JITting a large project such as Boost it's quite hard to figure out the problematic inline asm without debug location. This patch provides debug location printout before the JIT aborts due to inline asm. printDebugLoc() was exposed from MachineInstr.cpp and reused here.

If the JIT run with debug info, don't bomb on DBG_VALUE but ignore them.

Subject: [PATCH 376/906] Don't emit structors for available_externally globals
 (PR19933)

We would previously assert here when trying to figure out the section
for the global.

This makes us handle the situation more gracefully since the IR isn't
malformed.

Subject: [PATCH 378/906] DebugInfo: Reapply r209984 (reverted in r210143),
 asserting that abstract DbgVariables have DIEs.

Abstract variables within abstract scopes that are entirely optimized
away in their first inlining are omitted because their scope is not
present so the variable is never created. Instead, we should ensure the
scope is created so the variable can be added, even if it's been
optimized away in its first inlining.

This fixes the incorrect debug info in missing-abstract-variable.ll
(added in r210143) and passes an asserts self-hosting build, so
hopefully there's not more of these issues left behind... *fingers
crossed*.

Subject: [PATCH 386/906] PR19388: DebugInfo: Emit dead arguments in their
 originally declared order.

Unused arguments were not being added to the argument list, but instead
treated as arbitrary scope variables. This meant they weren't carefully
added in the original argument order.

In this particular example, though, it turns out the argument is only
/mostly/ unused (well, actually it's entirely used, but in a specific
way). It's a struct that, due to ABI reasons, is decomposed into chunks
(exactly one chunk, since it has one member) and then passed. Since only
one of those chunks is used (SROA, etc, kill the original reconstitution
code) we don't have a location to describe the whole variable.

In this particular case, since the struct consists of just the one int,
once we have partial location information, this should have a location
that describes the entire variable (since the piece is the entirety of
the object).

And at some point we'll need to describe the location of even /entirely/
unused arguments so that they can at least be printed on function entry.

Subject: [PATCH 400/906] [PPC64LE] Temporarily disable VSX support in
 little-endian mode

This is a preliminary patch for the PowerPC64LE support.  In stage 1
of the vector support, we will support the VMX (Altivec) instruction
set, but will not yet support the VSX instructions.  This is merely a
staging issue to provide functional vector support as soon as
possible.

Subject: [PATCH 402/906] Add a new attribute called 'jumptable' that creates
 jump-instruction tables for functions marked with this attribute. It includes
 a pass that rewrites all indirect calls to jumptable functions to pass
 through these tables.

This also adds backend support for generating the jump-instruction tables on ARM and X86.
Note that since the jumptable attribute creates a second function pointer for a
function, any function marked with jumptable must also be marked with unnamed_addr.

Subject: [PATCH 404/906] [PPC64LE] Correct vperm -> shuffle transform for
 little endian

As discussed in cfe commit r210279, the correct little-endian
semantics for the vec_perm Altivec interfaces are implemented by
reversing the order of the input vectors and complementing the permute
control vector.  This converts the desired permute from little endian
element order into the big endian element order that the underlying
PowerPC vperm instruction uses.  This is represented with a
ppc_altivec_vperm intrinsic function.

The instruction combining pass contains code to convert a
ppc_altivec_vperm intrinsic into a vector shuffle operation when the
intrinsic has a permute control vector (mask) that is a constant.
However, the vector shuffle operation assumes that vector elements are
in natural order for their endianness, so for little endian code we
will get the wrong result with the existing transformation.

This patch reverses the semantic change to vec_perm that was performed
in altivec.h by once again swapping the input operands and
complementing the permute control vector, returning the element
ordering to little endian.

The correctness of this code is tested by the new perm.c test added in
a previous patch, and by other tests in the test suite that fail
without this patch.

Subject: [PATCH 405/906] Add "-format darwin" to llvm-nm to be like darwin's
 nm(1) -m output.

This is a first step in seeing if it is possible to make llvm-nm produce
the same output as darwin's nm(1).  Darwin's default format is bsd but its
-m output prints the longer Mach-O specific details.  For now I added the
"-format darwin" to do this (whos name may need to change in the future).
As there are other Mach-O specific flags to nm(1) which I'm hoping to add some
how in the future.  But I wanted to see if I could get the correct output for
-m flag using llvm-nm and the libObject interfaces.

I got this working but would love to hear what others think about this approach
to getting object/format specific details printed with llvm-nm.

Subject: [PATCH 410/906] Fixed several correctness issues in
 SeparateConstOffsetFromGEP

Most issues are on mishandling s/zext.

Fixes:

1. When rebuilding new indices, s/zext should be distributed to
sub-expressions. e.g., sext(a +nsw (b +nsw 5)) = sext(a) + sext(b) + 5 but not
sext(a + b) + 5. This also affects the logic of recursively looking for a
constant offset, we need to include s/zext into the context of the searching.

2. Function find should return the bitwidth of the constant offset instead of
always sign-extending it to i64.

3. Stop shortcutting zext'ed GEP indices. LLVM conceptually sign-extends GEP
indices to pointer-size before computing the address. Therefore, gep base,
zext(a + b) != gep base, a + b

Improvements:

1. Add an optimization for splitting sext(a + b): if a + b is proven
non-negative (e.g., used as an index of an inbound GEP) and one of a, b is
non-negative, sext(a + b) = sext(a) + sext(b)

2. Function Distributable checks whether both sext and zext can be distributed
to operands of a binary operator. This helps us split zext(sext(a + b)) to
zext(sext(a) + zext(sext(b)) when a + b does not signed or unsigned overflow.

Refactoring:

Merge some common logic of handling add/sub/or in find.

Testing:

Add many tests in split-gep.ll and split-gep-and-gvn.ll to verify the changes
we made.

Subject: [PATCH 412/906] [PPC64LE] Add test case for r210282 commit

Chandler correctly pointed out that I need an LLVM IR test for
r210282, which modified the vperm -> shuffle transform for little
endian PowerPC.  This patch provides that test.

Subject: [PATCH 413/906] Correctly set the comdat symbol on COFF.

We extended the .section syntax to allow multiple sections with the
same name but different comdats, but currently we don't make sure that
the output section has that comdat symbol.

That happens to work with the code llc produces currently because it looks like

.section secName, "dr", one_only, "COMDATSym"
.globl COMDATSym
COMDATSym:
....

but that is not very friendly to anyone coding in assembly or even to
llc once we get comdat support in the IR.

This patch changes the coff object writer to make sure the comdat symbol is
output just after the section symbol, as required by the coff spec.

Subject: [PATCH 416/906] Allow aliases to be unnamed_addr.

Alias with unnamed_addr were in a strange state. It is stored in GlobalValue,
the language reference talks about "unnamed_addr aliases" but the verifier
was rejecting them.

It seems natural to allow unnamed_addr in aliases:

* It is a property of how it is accessed, not of the data itself.
* It is perfectly possible to write code that depends on the address
of an alias.

This patch then makes unname_addr legal for aliases. One side effect is that
the syntax changes for a corner case: In globals, unnamed_addr is now printed
before the address space.

Subject: [PATCH 418/906] Remove clang-specific libxml2 check from CMake

clang's own CMake setup handles this as of r210308.

The CMAKE_CROSSCOMPILING special-case will no longer be hard-coded. This was
clearly site-specific to someone's local configuration and should be passed in
at configure time if needed with e.g. -DLIBXML2_LIBRARIES=... (the libxml2
target I tried here doesn't even support liblzma so it's *way* off).

Subject: [PATCH 419/906] Fix PR19657 (scalar loads not combined into vector
 load) If we have common uses on separate paths in the tree; process the one
 with greater common depth first. This makes sure that we do not assume we
 need to extract a load when it is actually going to be part of a vectorized
 tree.

Subject: [PATCH 421/906] Added select flavour for ABS and NEG(ABS)

This patch can identify
  ABS(X) ==> (X >s 0) ? X : -X and (X >s -1) ? X : -X
  ABS(X) ==> (X <s 0) ? -X : X and (X <s 1) ? -X : X
  NABS(X) ==> (X >s 0) ? -X : X and (X >s -1) ? -X : X
  NABS(X) ==> (X <s 0) ? X : -X and (X <s 1) ? X : -X

and can transform
  ABS(ABS(X)) -> ABS(X)
  NABS(NABS(X)) -> NABS(X)

Differential Revision: http://reviews.llvm.org/D3658

Subject: [PATCH 427/906] [PPC64LE] Fix lowering of BUILD_VECTOR and
 SHUFFLE_VECTOR for little endian

This patch fixes a couple of lowering issues for little endian
PowerPC.  The code for lowering BUILD_VECTOR contains a number of
optimizations that are only valid for big endian.  For now, we disable
those optimizations for correctness.  In the future, we will add
analogous optimizations that are correct for little endian.

When lowering a SHUFFLE_VECTOR to a VPERM operation, we again need to
make the now-familiar transformation of swapping the input operands
and complementing the permute control vector.  Correctness of this
transformation is tested by the accompanying test case.

The use cases look like the following:
    x->a = y->a + 10
    x->b = y->b + 12

Subject: [PATCH 432/906] Remove DWARF3 testing of
 test/DebugInfo/X86/gnu-public-names.ll

This was added to test that DW_AT_GNU_pubnames used sec_offset in DWARF4
and data4 in DWARF3 and below. Since then we've updated
DW_AT_GNU_pubnames to be a flag, rather than a section offset anyway.

Granted this still differs between DWARF 3 and DWARF 4
(FORM_flag_present versun FORM_flag) but it doesn't seem worthwhile
testing that codepath again here. It's covered adequately in many other
test cases.

And while I'm here, don't hardcode the byte size of the compile unit -
it's not relevant to this test and just makes it brittle if/when
anything changes in the way this CU is emitted.

Subject: [PATCH 434/906] Match the full hex offsets in
 test/DebugInfo/X86/gnu-public-names.ll

These checks were accidentally skipping the 0x prefix in the hex
offsets, then cunningly ignoring the prefix in the use of those captured
values.

Except in the case of the unit length, where the match was only matching
the leading '0' before the x in the 0x prefix, then matching that
against the length. We can't actually express the length association
here, as the length field in the Compile Unit header does not include
the length field itself, but the length field in the pubnames section
/does/ include the size of the length field in the Compile Unit header -
so the two numbers are actually 4 bytes different. Just skip matching
that.

Subject: [PATCH 436/906] Fix a few issues with comdat handling on COFF.

* Section association cannot use just the section name as many
sections can have the same name. With this patch, the comdat symbol in
an assoc section is interpreted to mean a symbol in the associated
section and the mapping is discovered from it.

* Comdat symbols were not being set correctly. Instead we were getting
whatever was output first for that section.

A consequence is that associative sections now must use .section to
set the association. Using .linkonce would not work since it is not
possible to change a sections comdat symbol (it is used to decide if
we should create a new section or reuse an existing one).

This includes r210298, which was reverted because it was asserting
on an associated section having the same comdat as the associated
section.

Subject: [PATCH 438/906] MC: prevent early DCE of empty sections

Prevent the early elimination of sections in the object writer.  There may be
references to the section itself by other symbols, which may potentially not be
possible to resolve.  ML (Visual Studio's Macro Assembler) also seems to retain
empty sections.

The elimination of symbols and sections which are unused should really occur at
the link phase.  This will not cause any change in the resulting binary, simply
in the generated object files.

The adjustments to the other unit tests account for the fluctuating section
index caused by the appearance of sections which were previously discarded.

Subject: [PATCH 439/906] InstCombine: Canonicalize addrspacecast between
 different element types

addrspacecast X addrspace(M)* to Y addrspace(N)*

-->

bitcast X addrspace(M)* to Y addrspace(M)*
addrspacecast Y addrspace(M)* to Y addrspace(N)*

Updat all affected tests and add several new tests in addrspacecast.ll.

This patch is based on http://reviews.llvm.org/D2186 (authored by Matt
Arsenault) with fixes and more tests.

Subject: [PATCH 440/906] DebugInfo: pubnames: include file-local (static or
 anonymous namespace) variables and anonymous namespaces themselves.

Still some issues with name qualification, FIXMEs added to test cases
and fixes will come next.

Subject: [PATCH 441/906] DebugInfo: Use the scope of the function declaration,
 if any, to name a function in DWARF pubnames

This ensures that member functions, for example, are entered into
pubnames with their fully qualified name, rather than inside the global
namespace.

Subject: [PATCH 445/906] Fix the MachineScheduler's logic for updating ready
 times for in-order.

Now the scheduler updates a node's ready time as soon as it is
scheduled, before releasing dependent nodes. There was a reason I
didn't do this initially but it no longer applies.

A53 is in-order and was running into an issue where nodes where added
to the readyQ too early. That's now fixed.

This also makes it easier for custom scheduling strategies to build
heuristics based on the actual cycles that the node was scheduled at.

The only impact on OOO (sandybridge/cyclone) is that ready times will
be slightly more accurate. I didn't measure any significant regressions.

Subject: [PATCH 449/906] tools: add a high level explanation for WoA EH data

Add a brief explanation of the data section layout for the unwind data that the
Windows on ARM EH models.  This is simply to provide a rough idea of the layout
of the code involved in the decoding of the unwinding.  Details on the involved
data structures are available in the associated support header.  The bulk of it
is related to printing out the byte-code to help validate generation of WoA EH.

No functional change.

 //===----------------------------------------------------------------------===//
 
+// Windows on ARM uses a series of serialised data structures (RuntimeFunction)
+// to create a table of information for unwinding.  In order to conserve space,
+// there are two different ways that this data is represented.
+//
+// For functions with canonical forms for the prologue and epilogue, the data
+// can be stored in a "packed" form.  In this case, the data is packed into the
+// RuntimeFunction's remaining 30-bits and can fully describe the entire frame.
+//
+//        +---------------------------------------+
+//        |         Function Entry Address        |
+//        +---------------------------------------+
+//        |           Packed Form Data            |
+//        +---------------------------------------+
+//
+// This layout is parsed by Decoder::dumpPackedEntry.  No unwind bytecode is
+// associated with such a frame as they can be derived from the provided data.
+// The decoder does not synthesize this data as it is unnecessary for the
+// purposes of validation, with the synthesis being required only by a proper
+// unwinder.
+//
+// For functions that are large or do not match canonical forms, the data is
+// split up into two portions, with the actual data residing in the "exception
+// data" table (.xdata) with a reference to the entry from the "procedure data"
+// (.pdata) entry.
+//
+// The exception data contains information about the frame setup, all of the
+// epilouge scopes (for functions for which there are multiple exit points) and
+// the associated exception handler.  Additionally, the entry contains byte-code
+// describing how to unwind the function (c.f. Decoder::decodeOpcodes).
+//
+//        +---------------------------------------+
+//        |         Function Entry Address        |

+//        |      Exception Data Entry Address     |
+//        +---------------------------------------+
+//
+// This layout is parsed by Decoder::dumpUnpackedEntry.  Such an entry must
+// first resolve the exception data entry address.  This structure
+// (ExceptionDataRecord) has a variable sized header
+// (c.f. ARM::WinEH::HeaderWords) and encodes most of the same information as
+// the packed form.  However, because this information is insufficient to
+// synthesize the unwinding, there are associated unwinding bytecode which make
+// up the bulk of the Decoder.
+//
+// The decoder itself is table-driven, using the first byte to determine the
+// opcode and dispatching to the associated printing routine.  The bytecode
+// itself is a variable length instruction encoding that can fully describe the
+// state of the stack and the necessary operations for unwinding to the
+// beginning of the frame.
+//
+// The byte-code maintains a 1-1 instruction mapping, indicating both the width
+// of the instruction (Thumb2 instructions are variable length, 16 or 32 bits
+// wide) allowing the program to unwind from any point in the prologue, body, or
+// epilogue of the function.

Subject: [PATCH 450/906] ARM: correct assertion for long-calls on WoA

COFF/PE, so the relocation model is never static.  Loosen the assertion
accordingly.  The relocation can still be emitted properly, as it will be
converted to an IMAGE_REL_ARM_ADDR32 which will be resolved by the loader
taking the base relocation into account.  This is necessary to permit the
emission of long calls which can be controlled via the -mlong-calls option in
the driver.

This was incurring an unsatisfied dependency on CodeGen from LTO breaking
shared builds:

Undefined symbols for architecture x86_64:
  "llvm::initializeJumpInstrTablesPass(llvm::PassRegistry&)", referenced from:
      llvm::LTOCodeGenerator::initializeLTOPasses() in LTOCodeGenerator.cpp.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Removed as a temporary measure pending feedback from the author.

Subject: [PATCH 454/906] MC: fix ctor/dtor section for windows-itanium

This adjusts the section setup for the windows-itanium environment.  This
environment does not report to be a known windows msvc environment, even though
it is (nearly) identical to the MSVC environment for C code.

Subject: [PATCH 455/906] MC: make ELF .type handling more GNU AS compatible

GAS documents the .type directive as having an optional comma following the key
symbol name when using the STT_<TYPE_IN_UPPER_CASE> form.  However, it treats
the comma as optional in all cases.  This makes the IAS support both forms of
inputs.  Furthermore, the prefixed forms take either the upper case name or the
lower case alias.

The tests are split into two separate sets as the hash character serves as a
comment character on x86, which is tested in the second set by using arm-elf
which uses the at symbol as a comment character.

Subject: [PATCH 456/906] test: move some tests into ARM directory

Rather than requiring ARM support for the ELF tests (which is odd), move the
tests that require ARM into a subdirectory to use lit to disable them if the
support is not present.  Play this game to prevent disabling the ELF tests on
the Windows build bots as they have caught issues in the past with interactions
between various platforms.

Subject: [PATCH 458/906] include MipsGenFastISel.inc

Summary:
Included this file which is needed to enable tablegen generated functionality
for fast mips-isel

Test Plan:
This has no visible functionality by itself but just adding the include
file creates some issues so I have it as a separate patch.

Test Plan:
No functionality change. Run "make check" and run test-suite.
Because our servers are not yet running again I have not yet run test-suite.
I will further review myself before submission.

Subject: [PATCH 463/906] MC: fix text section characteristics for WoA

link.exe requires that the text section has the IMAGE_SCN_MEM_16BIT flag set.
Otherwise, it will treat the function as ARM.  If this occurs, then jumps to the
function will fail, switching from thumb to ARM mode execution.

With this change, it is possible to link using the MSVC linker as well.

Subject: [PATCH 467/906] Revert "Do materialize for floating point"

1) The commit was made despite profound lack of understanding:

   "I did not understand the comment about using dyn_cast instead of isa. I will
   commit as is and make the update after. You can explain what you meant to me."

   Commit first, understand later isn't OK.

2) Review comments were simply ignored:

   "Can you edit the summary to describe what the patch is for? It appears to be
   a list of commits at the moment."

3) The patch got LGTM'd off-list without any indication of readiness.

4) The public mailing list was excluded from patch review so all of this was
   hidden from the community.

This reverts commit r210414.

Subject: [PATCH 468/906] Ensure SmallVector::insert doesn't overwrite the last
 element in the range with the already-moved-from value

This would cause the last element in a range to be in a moved-from state
after an insert at a non-end position, losing that value entirely in the
process.

Side note: move_backward is subtle. It copies [A, B) to C-1 and down.
(the fact that it decrements both the second and third iterators before
the first movement is the subtle part... kind of surprising, anyway)

Subject: [PATCH 469/906] AsmMatchers: Use unique_ptr to manage ownership of
 MCParsedAsmOperand

I saw at least a memory leak or two from inspection (on probably
untested error paths) and r206991, which was the original inspiration
for this change.

I ran this idea by Jim Grosbach a few weeks ago & he was OK with it.
Since it's a basically mechanical patch that seemed sufficient - usual
post-commit review, revert, etc, as needed.

Subject: [PATCH 470/906] APFloat: x - NaN needs to flip the signbit of NaN
 when x is a number.

Because we don't have a separate negate( ) function, 0 - NaN does double-duty as the IEEE-754 negate( ) operation, which (unlike most FP ops) *does* attach semantic meaning to the signbit of NaN.

Subject: [PATCH 471/906] Fix some more moving-from-moved-from objects issues
 in SmallVector

(& because it makes it easier to test, this also improves
correctness/performance slightly by moving the last element in an insert
operation, rather than copying it)

Subject: [PATCH 472/906] SmallVectorTest: Remove some more robust checks added
 in r210429 since they caught some bugs I haven't fixed yet.

Specifically this caused inserting an element from a SmallVector into
itself when such an insertion would cause a reallocation. We have code
to handle this for non-reallocating cases, but it's not robust against
reallocation.

Before, we where looking at the size of the pointer type that specifies the
location from which to load the element. This did not make any sense at all.

This change fixes a bug in the delinearization where we failed to delinerize
certain load instructions.

Subject: [PATCH 477/906] SmallVector: Improve test coverage for insert with
 repetition

To test cases that involve actual repetition (> 1 elements), at least
one element before the insertion point, and some elements of the
original range that still fit in that range space after insertion.

Actually we need coverage for the inverse case too (where no elements
after the insertion point fit into the previously allocated space), but
this'll do for now, and I might end up rewriting bits of SmallVector to
avoid that special case anyway.

Subject: [PATCH 483/906] [SeparateConstOffsetFromGEP] inbounds zext => sext
 for better splitting

For each array index that is in the form of zext(a), convert it to sext(a)
if we can prove zext(a) <= max signed value of typeof(a). The conversion
helps to split zext(x + y) into sext(x) + sext(y).

Subject: [PATCH 489/906] Fix line numbers for code inlined from __nodebug__
 functions.

Instructions from __nodebug__ functions don't have file:line
information even when inlined into no-nodebug functions. As a result,
intrinsics (SSE and other) from <*intrin.h> clang headers _never_
have file:line information.

With this change, an instruction without !dbg metadata gets one from
the call instruction when inlined.

Fixes PR19001.

Subject: [PATCH 493/906] [X86] Use ADD/SUB instead of INC/DEC for Silvermont

According to Intel Software Optimization Manual
on Silvermont INC or DEC instructions require
an additional uop to merge the flags.
As a result, a branch instruction depending
on an INC or a DEC instruction incurs a 1 cycle penalty.

Differential Revision: http://reviews.llvm.org/D3990

Subject: [PATCH 494/906] [DAG] Expose NoSignedWrap, NoUnsignedWrap and Exact
 flags to SelectionDAG.

This patch modifies SelectionDAGBuilder to construct SDNodes with associated
NoSignedWrap, NoUnsignedWrap and Exact flags coming from IR BinaryOperator
instructions.

Added a new SDNode type called 'BinaryWithFlagsSDNode' to allow accessing
nsw/nuw/exact flags during codegen.

Patch by Marcello Maggioni.

Subject: [PATCH 495/906] [X86] Avoid emitting unnecessary test instructions.

This patch teaches the backend how to check for the 'NoSignedWrap' flag on
binary operations to improve the emission of 'test' instructions.

If the result of a binary operation is known not to overflow we know that
resetting the Overflow flag is unnecessary and so we can avoid emitting
the test instruction.

Patch by Marcello Maggioni.

Subject: [PATCH 500/906] [PPC64LE] Generate correct little-endian code for
 v16i8 multiply

The existing code in PPCTargetLowering::LowerMUL() for multiplying two
v16i8 values assumes that vector elements are numbered in big-endian
order.  For little-endian targets, the vector element numbering is
reversed, but the vmuleub, vmuloub, and vperm instructions still
assume big-endian numbering.  To account for this, we must adjust the
permute control vector and reverse the order of the input registers on
the vperm instruction.

The existing test/CodeGen/PowerPC/vec_mul.ll is updated to be executed
on powerpc64 and powerpc64le targets as well as the original powerpc
(32-bit) target.

Subject: [PATCH 503/906] [X86] Add target combine rules for horizontal
 add/sub.

This patch adds new target specific combine rules to identify horizontal
add/sub idioms from BUILD_VECTOR dag nodes.

This patch also teaches the DAGCombiner how to canonicalize sequences of
insert_vector_elt dag nodes according to the following rule:

  (insert_vector_elt (insert_vector_elt A, I0), I1) ->
    (insert_vecto_elt (insert_vector_elt A, I1), I0)

This new canonicalization rule only triggers if the inner insert_vector
dag node has exactly one use; also, both indices must be known constants,
and I1 < I0.
This last rule made it possible to write a simpler algorithm to identify
horizontal add/sub patterns because now we don't have to worry about the
ordering of insert_vector_elt dag nodes.

Subject: [PATCH 508/906] Fold FEnv.h into the implementation

Support headers shouldn't use config.h definitions, and they should never be
undefined like this.

ConstantFolding.cpp was the only user of this facility and already includes
config.h for other math features, so it makes sense to move the checks there at
point of use.

(The implicit config.h was also quite dangerous -- removing the FEnv.h include
would have silently disabled math constant folding without causing any tests to
fail. Need to investigate -Wundef once the cleanup is done.)

This eliminates the last config.h include from LLVM headers, paving the way for
more consistent configuration checks.

Subject: [PATCH 509/906] Remove old fenv.h workaround for a historic clang
 driver bug

Tested and works fine with clang using libstdc++.

All indications are that this was fixed some time ago and isn't a problem with
any clang version we support.

I've added a note in PR6907 which is still open for some reason.

Bug itself has been fixed by principal changes in MergeFunctions. Though
special checks for functions merging are still actual. And the test has
been accepted with slight modifications.

Subject: [PATCH 512/906] ARM: add VLA extension for WoA Itanium ABI

The armv7-windows-itanium environment is nearly identical to the MSVC ABI. It
has a few divergences, mostly revolving around the use of the Itanium ABI for
C++. VLA support is one of the extensions that are amongst the set of the
extensions.

This adds support for proper VLA emission for this environment. This is
somewhat similar to the handling for __chkstk emission on X86 and the large
stack frame emission for ARM. The invocation style for chkstk is still
controlled via the -mcmodel flag to clang.

Make an explicit note that this is an extension.

+^^^^^^^^^^^^^^^^^^^^^^
+
+The reference implementation (Microsoft Visual Studio 2012) does not permit the
+emission of Variable Length Arrays (VLAs).
+
+The Windows ARM Itanium ABI extends the base ABI by adding support for emitting
+a dynamic stack allocation.  When emitting a variable stack allocation, a call
+to ``__chkstk`` is emitted unconditionally to ensure that guard pages are setup
+properly.  The emission of this stack probe emission is handled similar to the
+standard stack probe emission.
+
+The MSVC environment does not emit code for VLAs currently.

Subject: [PATCH 514/906] Generate better location ranges for some
 register-described variables.

Don't terminate location ranges for register-described variables
at the end of machine basic block if this register is never modified
in the function body, except for the prologue and epilogue. Prologue
location is guessed by FrameSetup flags on MachineInstructions, while
epilogue location is deduced from debug locations of instructions
in the basic blocks ending with return instructions.

This patch is mostly targeted to fix non-trivial debug locations for
variables addressed via stack and frame pointers.

It is not really a generic fix. We can still produce poor debug info
for register-described variables if this register *is* modified somewhere
in the function, but in unrelated places. This might be the case for the debug
info in optimized binaries (e.g. for local variables in inlined functions).
LiveDebugVariables pass in CodeGen attempts to fix this problem by adjusting
DBG_VALUE instructions, but this pass is tied to greedy register allocator,
which is used in optimized builds only. Proper fix would likely involve
generalizing LiveDebugVariables to all register allocators. See more discussion
in http://reviews.llvm.org/D3933 review thread.

I'm proceeding with this patch to fix immediate severe problems and
important cases, e.g. fix completely broken debug info with AddressSanitizer
and fix PR19307 (missing debug info for by-value std::string arguments).

Subject: [PATCH 515/906] [PPC64LE] Generate correct code for unaligned
 little-endian vector loads

The code in PPCTargetLowering::PerformDAGCombine() that handles
unaligned Altivec vector loads generates a lvsl followed by a vperm.
As we've seen in numerous other places, the vperm instruction has a
big-endian bias, and this is fixed for little endian by complementing
the permute control vector and swapping the input operands.  In this
case the lvsl is providing the permute control vector.  Rather than
generating an lvsl and a complement operation, it is sufficient to
generate an lvsr instruction instead.  Thus for LE code generation we
will generate an lvsr rather than an lvsl, and swap the other input
arguments on the vperm.

The existing test/CodeGen/PowerPC/vec_misalign.ll is updated to test
the code generation for PPC64 and PPC64LE, in addition to the existing
PPC32/G5 testing.

Subject: [PATCH 516/906] SmallVector: support resize(N) with move-only types

Unfortunately there's no way to elegantly do this with pre-canned
algorithms. Using a generating iterator doesn't work because you default
construct for each element, then move construct into the actual slot
(bad for copy but non-movable types, and a little unneeded overhead even
in the move-only case), so just write it out manually.

This solution isn't exception safe (if one of the element's ctors calls
we don't fall back, destroy the constructed elements, and throw on -
which std::uninitialized_fill does do) but SmallVector (and LLVM) isn't
exception safe anyway.

Subject: [PATCH 518/906] Removing an "if (!this)" check from two print
 methods.  The condition will never be true in a well-defined context.  The
 checking for null pointers has been moved into the caller logic so it does
 not rely on undefined behavior.

Subject: [PATCH 520/906] [ConstantHoisting][X86] Improve the cost model for
 small constants with large types (i64 and above).

This improves the X86 cost model for small constants with large types. Before
this commit we would even hoist trivial constants such as i96 2.

This is related to <rdar://problem/17070936>

We were hitting an assert if FastISel couldn't create the load or store we
requested. Currently this happens for large frame-local addresses, though
CodeGen could be improved there.

Subject: [PATCH 525/906] AArch64: teach FastISel how to handle offset
 FrameIndices

Previously we were abandonning the attempt, leading to some combination of
extra work (when selection of a load/store fails completely) and inferior code
(when this leads to a real memcpy call instead of inlining).

Subject: [PATCH 526/906] X86: elide comparisons after cmpxchg instructions.

The C++ and C semantics of the compare_and_swap operations actually
require us to return a boolean "success" value. In LLVM terms this
means a second comparison of the output of "cmpxchg" against the input
desired value.

However, x86's "cmpxchg" instruction sets all flags for the comparison
formed, so we can skip any secondary comparison. (N.b. this isn't true
for cmpxchg8b/16b, which only set ZF).

Subject: [PATCH 528/906] AArch64: disallow x30 & x29 as the destination for
 indirect tail calls

As Ana Pazos pointed out, these have to be restored to their incoming values
before a function returns; i.e. before the tail call. So they can't be used
correctly as the destination register.

Subject: [PATCH 531/906] Condition codes AL and NV are invalid in the aliases
 that use inverted condition codes (CINC, CINV, CNEG, CSET, and CSETM).

Matching aliases based on "immediate classes", when disassembling,
wasn't previously supported, hence adding MCOperandPredicate
into class Operand, and implementing the support for it
in AsmWriterEmitter.

The parsing for those aliases was already custom, so just adding
the missing condition into AArch64AsmParser::parseCondCode.

Subject: [PATCH 532/906] Add detection of OS X relocatable SDK to compiler-rt
 as a lit.util function

Clang's lit cfg already detects the currently selected SDK via
"xcrun --show-sdk-path". The same thing should be done for compiler-rt tests,
to make them work on recent OS X versions. Instead of duplicating the detection
code, this patch extracts the detection function into a lit.util method.

Subject: [PATCH 534/906] [PPC64LE] Recognize shufflevector patterns for little
 endian

Various masks on shufflevector instructions are recognizable as
specific PowerPC instructions (vector pack, vector merge, etc.).
There is existing code in PPCISelLowering.cpp to recognize the correct
patterns for big endian code.  The masks for these instructions are
different for little endian code due to the big-endian numbering
employed by these instructions.  This patch adds the recognition code
for little endian.

I've added a new test case test/CodeGen/PowerPC/vec_shuffle_le.ll for
this.  The existing recognizer test (vec_shuffle.ll) is unnecessarily
verbose and difficult to read, so I felt it was better to add a new
test rather than modify the old one.

Subject: [PATCH 537/906] SelectionDAG: Don't use MVT::Other to determine
 legality of ISD::SELECT_CC

The SelectionDAG bad a special case for ISD::SELECT_CC, where it would
allow targets to specify:

setOperationAction(ISD::SELECT_CC, MVT::Other, Expand);

to indicate that they wanted to expand ISD::SELECT_CC for all types.
This wasn't applied correctly everywhere, and it makes writing new
DAG patterns with ISD::SELECT_CC difficult.

Subject: [PATCH 538/906] Fix a bug in the Thumb1 ARM Load/Store optimizer

Previously, the basic block was searched for future uses of the base register,
and if necessary any writeback to the base register was reset using a SUB
instruction (e.g. before calling a function) just before such a use. However,
this step happened *before* the merged LDM/STM instruction was built. So if
there was (e.g.) a function call directly after the not-yet-formed LDM/STM,
the pass would first insert a SUB instruction to reset the base register,
and then (at the same location, incorrectly) insert the LDM/STM itself.

This patch fixes PR19972. Patch by Moritz Roth.

Subject: [PATCH 541/906] [X86] Improved target combine rules for selecting
 horizontal add/sub.

This patch slightly changes the algorithm introduced at revision 210477
to fix a problem where the algorithm was producing incorrect code for
the VEX.256 encoded versions of horizontal add/sub.

For these cases, we now try to split the two 256-bit vectors into
128-bit chunks before emitting horizontal add/sub dag nodes.

Added a new test case into haddsub-2.ll.

Subject: [PATCH 561/906] Revert "Patch by Ray Donnelly to print register names
 instead of numbers."

This reverts commit r206683.

The code was confusing SEH register numbers with DWARF register numbers.
The test case it was committed with was obviously incorrect.  The
disassembler was roundtripping '.seh_pushreg %rsi' as '.seh_pushreg
%rbp', and other exciting things.

Noticed by Vadim Chugunov.

We need to make sure only one new instruction is added when spilling
otherwise the register allocator may crash.

This fixes a crash in the game Antichamber.

Subject: [PATCH 568/906] R600/SI: Emit an error when attempting to spill VGPRs
 v4

I can't get VGPR spilling to work reliable, so for now just emit
an error when the register allocator tries to spill VGPRs.

v2:
  - Fix build
v3:
  - Added crash fix when spilling SPGRs
v4:
  - Use V_MOV_B32 as a dummy instruction instead of S_NOP

Subject: [PATCH 573/906] lit: warn when passed invalid pathname

It would previously say things like

  warning: input 'test/Frontend/foo.c' contained no tests

and have the user pull their hair trying to figure out what's wrong with that
file. This patch changes the message to the much clearer:

  warning: no such file or directory: 'test/Frontend/foo.c'

Subject: [PATCH 576/906] Remove support for runtime multi-threading.

This patch removes the functions llvm_start_multithreaded() and
llvm_stop_multithreaded(), and changes llvm_is_multithreaded()
to return a constant value based on the value of the compile-time
definition LLVM_ENABLE_THREADS.

Previously, it was possible to have compile-time support for
threads on, and runtime support for threads off, in which case
certain mutexes were not allocated or ever acquired.  Now, if the
build is created with threads enabled, mutexes are always acquired.

A test before/after patch of compiling a very large TU showed no
noticeable performance impact of this change.

Subject: [PATCH 586/906] CodeGen: refactor DwarfException

DwarfException served as a base class for exception handling directive emission.
However, this is also used by other exception models (e.g. Win64EH).  Rename
this class to EHStreamer and split it out of DwarfException.h.  NFC.

Use the opportunity to fix up some of the documentation comments to match
current LLVM style.  Also rename some functions to conform better with current
LLVM coding style.

Subject: [PATCH 591/906] Remove windows_error.

MSVC doesn't seem to provide any is_error_code_enum enumeration for the
windows errors.

Fortunately very few places in llvm have to handle raw windows errors, so
we can just construct the corresponding error_code directly.

Subject: [PATCH 593/906] MC: add enumeration of WinEH data encoding

Most Windows platforms use auxiliary data for unwinding.  This information is
stored in the .pdata section.  The encoding format for the data differs between
architectures and Windows variants.  Windows MIPS and Alpha use identical
formats; Alpha64 is the same with different widths.  Windows x86_64 and Itanium
share the representation.  All Windows CE entries are identical irrespective of
the architecture.  ARMv7 (Windows [NT] on ARM) has its own format.

This enumeration will become the differentiator once the windows EH emission
infrastructure is generalised, allowing us to emit the necessary unwinding
information for Windows on ARM.

Subject: [PATCH 598/906] Global merge for global symbols.

This commit is to improve global merge pass and support global symbol merge.
The global symbol merge is not enabled by default. For aarch64, we need some
more back-end fix to make it really benifit ADRP CSE.

Subject: [PATCH 599/906] Create macro INITIALIZE_TM_PASS.

Pass initialization requires to initialize TargetMachine for back-end
specific passes. This commit creates a new macro INITIALIZE_TM_PASS to
simplify this kind of initialization.

Subject: [PATCH 600/906] [X86] Refactor the logic to select horizontal
 adds/subs to a helper function.

This patch moves part of the logic implemented by the target specific
combine rules added at r210477 to a separate helper function.
This should make easier to add more rules for matching AVX/AVX2 horizontal
adds/subs.

This patch also fixes a problem caused by a wrong check performed on indices
of extract_vector_elt dag nodes in input to the scalar adds/subs.

New tests have been added to verify that we correctly check indices of
extract_vector_elt dag nodes when selecting a horizontal operation.

Subject: [PATCH 604/906] [mips][mips64r6] Improve tests affected by the
 changes to multiplies and divides

Summary:
MIPS32r6/MIPS64r6 support has not been added yet.

inlineasm-cnstrnt-reg.ll:
  Explicitly specify the CPU since it will not work on MIPS32r6/MIPS64r6
  when -integrated-as is the default. We can't change the mnemonic since the
  LO register is an implicit def of mtlo and MIPS32r6/MIPS64r6 has no
  instructions that use LO.

2008-08-01-AsmInline.ll:
  Explicitly specify the CPU since MIPS32r6/MIPS64r6 will correctly emit
  different code and this is a regression test.

mips64instrs.ll and mips64muldiv.ll
  Check registers and the way the multiply is used in m1

divrem.ll
  Check registers and use multiple filecheck prefixes to limit redundancy

Subject: [PATCH 607/906] R600/SI: Fix selection failure on scalar_to_vector

There seem to be only 2 places that produce these,
and it's kind of tricky to hit them.

Also fixes failure to bitcast between i64 and v2f32,
although this for some reason wasn't actually broken in the
simple bitcast testcase, but did in the scalar_to_vector one.

Subject: [PATCH 611/906] R600/SI: Fix backwards names for local atomic
 instructions.

The manual lists them as *_RTN_U32, not *_U32_RTN, which is more
consistent with how every other sized instruction is named.

Subject: [PATCH 621/906] Use std::error_code instead of llvm::error_code.

The idea of this patch is to turn llvm/Support/system_error.h into a
transitional header that just brings in the erorr_code api to the llvm
namespace. I will remove it shortly afterwards.

The cases where the general idea needed some tweaking:

* std::errc is a namespace in msvc, so we cannot use "using std::errc". I could
add an #ifdef, but there were not that many uses, so I just added std:: to
them in this patch.

* Template specialization had to be moved to the std namespace in this
patch set already.

* The msvc implementation of default_error_condition doesn't seem to
provide the same transformations as we need. Not too surprising since
the standard doesn't actually say what "equivalent" means. I fixed the
problem by keeping our old mapping and using it at error_code
construction time.

Despite these shortcomings I think this is still a good thing. Some reasons:

* The different implementations of system_error might improve over time.
* It removes 925 lines of code from llvm already.
* It removes 6313 bytes from the text segment of the clang binary when
it is built with gcc and 2816 bytes when building with clang and
libstdc++.

+//  This file implements a mapping from windows errors to posix ones.
+//  The standard doesn't define what the equivalence is from system
+//  errors to generic ones. The one implemented in msvc is too conservative
+//  for llvm, so we do an extra mapping when constructing an error_code
+//  from an windows error. This allows the rest of llvm to simple checks
+//  like "EC == std::errc::file_exists" and have it work on both posix and
+//  windows.

Subject: [PATCH 622/906] R600/SI: Fix bitcast between v2i32 and f64

This is the same problem fixed in r210664 for more types.

The test passes without this fix. For some reason
I'm only hitting this when creating selects lowered
to v2i32 selects.

Subject: [PATCH 623/906] llvm-mc: Add option for prefering hex format
 disassembly.

Previously there was a separate mode entirely (--hdis vs.
--disassemble). It makes a bit more sense for the immediate printing
style to be a flag for --disassmeble rather than an entirely different
thing.

Subject: [PATCH 624/906] ARM: honor hex immediate formatting for ldr/str i12
 offsets.

Previously we would always print the offset as decimal, regardless of
the formatting requested. Now we use the formatImm() helper so the value
is printed as the client (LLDB in the motivating example) requested.

Before:
ldr.w r8, [sp, #180] @ always

After:
ldr.w r8, [sp, #0xb4] @ when printing hex immediates
ldr.w r8, [sp, #0180] @ when printing decimal immediates

+// Contains all of the Cortex-A57 specific SchedWriteRes types. The approach
+// below is to define a generic SchedWriteRes for every combination of
+// latency and microOps. The naming conventions is to use a prefix, one field
+// for latency, and one or more microOp count/type designators.
+//   Prefix: A57Write
+//   Latency: #cyc
+//   MicroOp Count/Types: #(B|I|M|L|S|X|W|V)
+//
+// e.g. A57Write_6cyc_1I_6S_4V means the total latency is 6 and there are
+//      11 micro-ops to be issued down one I pipe, six S pipes and four V pipes.

Subject: [PATCH 631/906] Don't acquire the mutex during the destructor of
 PassRegistry.

This destructor is run as part of static program termination, and
so all ManagedStatics (including this lock) will have been
destroyed by llvm_shutdown.  Furthermore, if there is actually
a race condition during static program termination, then we are
just hiding a bug somewhere else, because other threads should
not be running at this point.

Subject: [PATCH 635/906] Do not register and de-register
 PassRegistrationListeners during construction and destruction.

PassRegistrationListener is intended for use as a generic listener.
In some cases, PassRegistrationListener-derived classes were being
created, and automatically registered and de-registered in static
constructors and destructors.  Since ManagedStatics are destroyed
prior to program shutdown, this leads to errors where an attempt is
made to access a ManagedStatic that has already been destroyed.

Subject: [PATCH 641/906] Fix verifier for GlobalAliases to avoid recursing
 into global initializers.

The verifier follows GlobalAlias operands so that it can detect cycles of
alias definitions. It was doing this in a way that caused it to also recurse
through initializers for the GlobalValue aliasees, and it would fail when
an initializer refers to a global that is a declaration and not a definition.
This patch causes it to stop recursing when it hits a global definition.
<rdar://problem/17277451>

Subject: [PATCH 652/906] [mips][mips64r6] Replace m[tf]hi, m[tf]lo, mult,
 multu, dmult, dmultu, div, ddiv, divu, ddivu for MIPS32r6/MIPS64.

Summary:
The accumulator-based (HI/LO) multiplies and divides from earlier ISA's have
been removed and replaced with GPR-based equivalents. For example:
  div $1, $2
  mflo $3
is now:
  div $3, $1, $2

This patch disables the accumulator-based multiplies and divides for
MIPS32r6/MIPS64r6 and uses the GPR-based equivalents instead.

Renamed expandPseudoDiv to insertDivByZeroTrap to better describe the
behaviour of the function.

MipsDelaySlotFiller now invalidates the liveness information when moving
instructions to the delay slot. Without this, divrem.ll will abort since
%GP ends up used before it is defined.

Subject: [PATCH 653/906] [X86] Teach how to combine AVX and AVX2 horizontal
 binop on packed 256-bit vectors.

This patch adds target combine rules to match:
 - [AVX] Horizontal add/sub of packed single/double precision floating point
   values from 256-bit vectors;
 - [AVX2] Horizontal add/sub of packed integer values from 256-bit vectors.

+/// \brief Emit a sequence of two 128-bit horizontal add/sub followed by
+/// a concat_vector. 
+///
+/// This is a helper function of PerformBUILD_VECTORCombine.
+/// This function expects two 256-bit vectors called V0 and V1.
+/// At first, each vector is split into two separate 128-bit vectors.
+/// Then, the resulting 128-bit vectors are used to implement two
+/// horizontal binary operations. 
+///
+/// The kind of horizontal binary operation is defined by \p X86Opcode.
+///
+/// \p Mode specifies how the 128-bit parts of V0 and V1 are passed in input to
+/// the two new horizontal binop.
+/// When Mode is set, the first horizontal binop dag node would take as input
+/// the lower 128-bit of V0 and the upper 128-bit of V0. The second
+/// horizontal binop dag node would take as input the lower 128-bit of V1
+/// and the upper 128-bit of V1.
+///   Example:
+///     HADD V0_LO, V0_HI
+///     HADD V1_LO, V1_HI
+///
+/// Otherwise, the first horizontal binop dag node takes as input the lower
+/// 128-bit of V0 and the lower 128-bit of V1, and the second horizontal binop
+/// dag node takes the the upper 128-bit of V0 and the upper 128-bit of V1.
+///   Example:
+///     HADD V0_LO, V1_LO
+///     HADD V0_HI, V1_HI

Subject: [PATCH 655/906] [mips][mips64r6] madd.[ds], msub.[ds], nmadd.[ds],
 and nmsub.[ds] are not available on MIPS32r6/MIPS64r6

Summary:
This patch updates both the assembler and the code generator.

MIPS32r6/MIPS64r6 replaces them with maddf.[ds] and msubf.[ds] which are fused
multiply-add/sub operations. We don't emit these yet, this patch only prevents the removed instructions from being emitted.

Depends on D3955

Subject: [PATCH 657/906] [X86] Teach how to dump the name of target node
 RDTSCP_DAG.

When I originally added node RDTSCP_DAG (r207127) I forgot to add
a string name for it in method 'getTargetNodeName'.

No functional change intended.

Subject: [PATCH 659/906] [mips] Use MTHC1 when it is available (MIPS32r2 and
 later) for both FP32 and FP64

Summary:
To make this work for both AFGR64 and FGR64 register sets, I've had to make the
instruction definition consistent with the white lie (that it reads the lower
32-bits of the register) when they are generated by expandBuildPairF64().

Corrected the definition of hasMips32r2() and hasMips64r2() to include
MIPS32r6 and MIPS64r6.

Depends on D3956

Subject: [PATCH 663/906] [mips][mips64r6] c.cond.fmt, mov[fntz], and
 mov[fntz].[ds] are not available on MIPS32r6/MIPS64r6

Summary:
c.cond.fmt has been replaced by cmp.cond.fmt. Where c.cond.fmt wrote to
dedicated condition registers, cmp.cond.fmt writes 1 or 0 to normal FGR's
(like the GPR comparisons).

mov[fntz] have been replaced by seleqz and selnez. These instructions
conditionally zero a register based on a bool in a GPR. The results can
then be or'd together to act as a select without, for example, requiring a third
register read port.

mov[fntz].[ds] have been replaced with sel.[ds]

MIPS64r6 currently generates unnecessary sign-extensions for most selects.
This is because the result of a SETCC is currently an i32. Bits 32-63 are
undefined in i32 and the behaviour of seleqz/selnez would otherwise depend
on undefined bits. Later, we will fix this by making the result of SETCC an
i64 on MIPS64 targets.

Depends on D3958

Subject: [PATCH 668/906] [mips][mips64r6] [sl][duw]xc1 are not available on
 MIPS32r6/MIPS64r6

Summary:
Folded mips64-fp-indexed-ls.ll into fp-indexed-ls.ll. To do so, the zext's in
mips64-fp-indexed-ls.ll were changed to implicit sign extensions (performed
by getelementptr). This does not affect the purpose of the test.

Depends on D4004

Subject: [PATCH 669/906] [mips][mips64r6] bc2[ft] are not available on
 MIPS32r6/MIPS64r6

Summary:
These instructions are not implemented for any MIPS ISA so we only need
testcases.

Depends on D4110

Subject: [PATCH 670/906] [mips][mips64r6] bc1[tf] are not available on
 MIPS32r6/MIPS64r6

Summary:
Also tightened up the acceptable condition operand for these instructions
on MIPS-I to MIPS-III. Support for $fcc[1-7] was added in MIPS-IV. Prior
to that only $fcc0 is acceptable.

We currently don't optimize (BEQZ (NOT $a), $target) and similar. It's
probably best to do this in InstCombine.

Depends on D4111

From 5eba90a861ff19cc2c49c7074565541978cfc83f Mon Sep 17 00:00:00 2001
From: James Molloy <james.molloy@arm.com>
Date: Thu, 12 Jun 2014 15:18:33 +0000
Subject: [PATCH 671/906] Disable the load/store optimization pass for Thumb-1.

Moritz's changes have improved codegen a lot, but further testing showed significant correctness problems. Disable by default until these have been worked out.

Patch by Moritz Roth!

Subject: [PATCH 672/906] Revert "SelectionDAG: Enable (and (setcc x), (setcc
 y)) -> (setcc (and x, y)) for vectors"

This reverts commit r210540, adds a testcase for the regression it
caused, and marks the R600 test it was supposed to fix as XFAIL.

Subject: [PATCH 673/906] Remove pimpl class from PassRegistry.

Since removeRegistrationListener is no longer called during static
destruction, we can get rid of the pimpl in PassRegistry.

This should clean up the code somewhat, increase clarity, and also
allows us to put the Lock as a member of the class, instead of as a
ManagedStatic.

As part of this change, the PassInfo class is moved from
PassSupport.h to its own file, to eliminate the otherwise circular
header dependency between PassRegistry.h and PassSupport.h

Subject: [PATCH 675/906] Remove system_error.h.

This is a minimal change to remove the header. I will remove the occurrences
of "using std::error_code" in a followup patch.

Subject: [PATCH 677/906] X86: stifle GCC warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

lib/Target/X86/X86TargetTransformInfo.cpp: In member function ‘virtual unsigned int {anonymous}::X86TTI::getIntImmCost(unsigned int, unsigned int, const llvm::APInt&, llvm::Type*) const’:
lib/Target/X86/X86TargetTransformInfo.cpp:920:60: warning: enumeral and non-enumeral type in conditional expression [enabled by default]

This seems like an unhelpful warning, but there doesnt seem to be a controlling
flag, so add an explicit cast to silence the warning.

Subject: [PATCH 679/906] Add missing "InitializerConstant" to global variable
 syntax in LangRef.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The syntax for Global Variables in LangRef is missing the initializer.
This syntax section was added in r199218 along with changes to the
dllexport/dllimport handling, and I guess it was just an oversight to omit the
initializer values. I’ve marked the initializer as optional because this syntax
is used for both declarations and definitions.

Subject: [PATCH 680/906] [llvm-symbolizer] Fix parsing DW_AT_ranges in Fission
 skeleton compile unit DIEs.

Turns out that DW_AT_ranges_base attribute sets the offset for
DW_AT_ranges values specified in the .dwo file, but not for DW_AT_ranges specified
in the skeleton compile unit DIE in the main executable. This is extremely confusing,
and would hopefully be fixed in DWARF-5 when it's finalized. For now this
behavior makes sense, as otherwise Fission would break DWARF consumers who
doesn't know anything about DW_AT_ranges_base.

Subject: [PATCH 682/906] CodeGen: enable mov.w/mov.t pairs with minsize for
 WoA

Windows on ARM uses COFF/PE which is intrinsically position independent.  For
the case of 32-bit immediates, use a pair-wise relocation as otherwise we may
exceed the range of operators.  This fixes a code generation crash when using
-Oz when targeting Windows on ARM.

Subject: [PATCH 685/906] LangRef: clarify that global declarations can have
 section and alignment info.

I'm not sure what it means to set a section for a declaration in another
translation unit, but there are some tests in the tree that do it so it seems
to be legal now regardless.

Subject: [PATCH 688/906] R600: Mostly remove remaining AMDIL intrinsics.

Delete all unused ones, and add new AMDGPU named intrinsics for
the ones that are. Handle the old AMDIL names for comptability (although
remove their GCCBuiltin names) and add tests since there weren't any
for these before.

Subject: [PATCH 689/906] GVN: Enable value forwarding for calloc

Enable value forwarding for loads from `calloc()` without an intervening
store.

This change extends GVN to handle the following case:

    %1 = tail call noalias i8* @calloc(i64 1, i64 4)
    %2 = bitcast i8* %1 to i32*
    ; This load is trivially constant zero
    %3 = load i32* %2, align 4

This is analogous to the handling for `malloc()` in the same places.
`malloc()` returns `undef`; `calloc()` returns a zero value.  Note that
it is correct to return zero even for out of bounds GEPs since the
result of such a GEP would be undefined.

Patch by Philip Reames!

Subject: [PATCH 707/906] [FastISel][X86] Add MachineMemOperand to load/store
 instructions.

This commit adds MachineMemOperands to load and store instructions. This allows
the peephole optimizer to fold load instructions. Unfortunatelly the peephole
optimizer currently doesn't run at -O0.

Subject: [PATCH 709/906] [DWARF parser] Fix broken address ranges
 construction.

Previous algorithm for constructing [Address ranges]->[Compile Units]
mapping was wrong. It somewhat relied on the assumption that address ranges
for different compile units may not overlap. It is not so.
For example, two compile units may contain the definition of the same
linkonce_odr function. These definitions will be merged at link-time,
resulting in equivalent .debug_ranges entries for both these units

Instead of sorting and merging original address ranges (from .debug_ranges
and .debug_aranges), implement a different approach: save endpoints
of all ranges, and then use a sweep-line approach to construct
the desired mapping. If we find that certain address maps to
several compilation units, we just pick any of them.

Subject: [PATCH 710/906] Move to a private function to initialize subtarget
 dependencies so we can use initializer lists for the ARMSubtarget and then
 use this to initialize a moved DataLayout on the subtarget from the
 TargetMachine.

Subject: [PATCH 717/906] [FastISel][X86] Add support for cvttss2si/cvttsd2si
 intrinsics.

This adds support for the cvttss2si/cvttsd2si intrinsics. Preceding
insertelement instructions are folded into the conversion instruction (if
possible).

Subject: [PATCH 723/906] R600: Don't call setOperationAction with things that
 aren't opcodes.

CondCode actions are set with setCondCodeAction.
This should have been a harmless bug since the values seem to only
collide only with nodes that don't need to be handled, and these are
already correctly setup elsewhere.

Subject: [PATCH 724/906] ARM: Fix fastcc calling convention for Thumb1

When targetting Thumb1 on a processor which has a VFP unit (which
is not accessible from Thumb1), we were converting the fastcc calling
convention to AAPCS-VFP, which is not possible.

Subject: [PATCH 728/906] [Win32] Let utils/not aware of abort(), aka
 llvm_unreachable(), in msvcrt.

It has exit code as 3. abort(), aka unreachable, may be handled as crash.

FIXME: Could we move this into Win32/Program.inc?

Subject: [PATCH 729/906] [mips][mips64r6] daddi is not available on MIPS64r6

Summary:
It's not emitted by the code generator so we only need assembler tests.

Also added missing daddi aliases from dsub mnemonics, and removed a couple
duplicate dsub tests.

Depends on D4112

Subject: [PATCH 730/906] [mips][mips64r6] b(ge|lt)zal are not available on
 MIPS32r6/MIPS64r6 and bal is a normal instruction

Summary:
b(ge|lt)zal have been removed in MIPS32r6/MIPS64r6. However, bal (an alias
for 'bgezal $zero, $offset') still remains with the same encoding it had
prior to MIPS32r6/MIPS64r6.

Updated the MipsNaCLELFStreamer, and MipsLongBranch to correctly handle the
MIPS32r6/MIPS64r6 BAL instruction in addition to the existing BAL_BR pseudo.

No changes were required to the CodeGen test that looks for BAL
(test/CodeGen/Mips/longbranch.ll) since the new instruction has the same
syntax.

Depends on D4113

Subject: [PATCH 731/906] [mips][mips64r6] bc1any[24] are not available on
 MIPS32r6/MIPS64r6

Summary:
These MIPS-3D instructions have never been implemented in LLVM so we only
add testcases.

Subject: [PATCH 732/906] [mips] Add cache and pref instructions

Summary:
cache and pref were added in MIPS-III, and MIPS32 but were re-encoded in
MIPS32r6/MIPS64r6 to use a 9-bit offset rather than the 16-bit offset
available to earlier cores.

Resolved the decoding conflict between pref and lwc3.

Depends on D4115

Subject: [PATCH 734/906] IR: add "cmpxchg weak" variant to support permitted
 failure.

This commit adds a weak variant of the cmpxchg operation, as described
in C++11. A cmpxchg instruction with this modifier is permitted to
fail to store, even if the comparison indicated it should.

As a result, cmpxchg instructions must return a flag indicating
success in addition to their original iN value loaded. Thus, for
uniformity *all* cmpxchg instructions now return "{ iN, i1 }". The
second flag is 1 when the store succeeded.

At the DAG level, a new ATOMIC_CMP_SWAP_WITH_SUCCESS node has been
added as the natural representation for the new cmpxchg instructions.
It is a strong cmpxchg.

By default this gets Expanded to the existing ATOMIC_CMP_SWAP during
Legalization, so existing backends should see no change in behaviour.
If they wish to deal with the enhanced node instead, they can call
setOperationAction on it. Beware: as a node with 2 results, it cannot
be selected from TableGen.

Currently, no use is made of the extra information provided in this
patch. Test updates are almost entirely adapting the input IR to the
new scheme.

Summary for out of tree users:
------------------------------

+ Legacy Bitcode files are upgraded during read.
+ Legacy assembly IR files will be invalid.
+ Front-ends must adapt to different type for "cmpxchg".
+ Backends should be unaffected by default.

Subject: [PATCH 739/906] Fix KillTheDoctor after r210725.

We don't map these windows errors to generic ones since errc::timed_out is
not defined on mingw. Just use the raw windows error value.

This code was never being used and any use of it would look fairly strange.
For example, it would try to map a object_error::parse_failed to
std::errc::invalid_argument.

Subject: [PATCH 742/906] opt: Initialize asm printers

Without initializing the assembly printers a shared library build of opt is
linked with these libraries whereas for a static build these libraries are dead
code eliminated. This is unfortunate for plugins in case they want to use them,
as they neither can rely on opt to provide this functionality nor can they link
the printers in themselves as this breaks with a shared object build of opt.

This patch calls InitializeAllAsmPrinters() from opt, which increases the static
binary size from 50MB -> 52MB on my system (all backends compiled) and causes no
measurable increase in the time needed to run 'make check'.

Subject: [PATCH 744/906] Atomics: switch direction of cmpxchg comparison

This has two benefits: it makes the result more suitable for direct
insertaion into the struct to emulate the new cmpxchg, and it means
the name we give the instruction matches its actual effect better.

Subject: [PATCH 745/906] Atomics: make use of the "cmpxchg weak" instruction.

This also simplifies the IR we create slightly: instead of working out
where success & failure should go manually, it turns out we can just
always jump to a success/failure block created for the purpose. Later
phases will sort out the mess without much difficulty.

Subject: [PATCH 746/906] Finishing touch for the std::error_code transition.

While std::error_code itself seems to work OK in all platforms, there
are few annoying differences with regards to the std::errc enumeration.

This patch adds a simple llvm enumeration, which will hopefully avoid build
breakages in other platforms and surprises as we get more uses of
std::error_code.

+// While std::error_code works OK on all platforms we use, there are some
+// some problems with std::errc that can be avoided by using our own
+// enumeration:
+//
+// * std::errc is a namespace in some implementations. That meas that ADL
+//   doesn't work and it is sometimes necessary to write std::make_error_code
+//   or in templates:
+//   using std::make_error_code;
+//   make_error_code(...);
+//
+//   with this enum it is safe to always just use make_error_code.
+//
+// * Some implementations define fewer names than others. This header has
+//   the intersection of all the ones we support.
+//
+// * std::errc is just marked with is_error_condition_enum. This means that
+//   common patters like AnErrorCode == errc::no_such_file_or_directory take
+//   4 virtual calls instead of two comparisons.

Subject: [PATCH 747/906] R600: Cleanup some old AMDIL stuff.

Move / delete some of the more obviously wrong
setOperationAction calls. Most of these are setting Expand
for types that aren't legal which is the default anyway.
Leave stuff that might require more thought on whether it's
junk or not as it is.

No functionality change.

Subject: [PATCH 748/906] X86: lower ATOMIC_CMP_SWAP_WITH_SUCCESS directly

Lowering this new node allows us to fold the almost universal
comparison for success before it's even formed. Instead we can create
a copy from EFLAGS and an X86ISD::SETCC operation since all "cmpxchg"
instructions set the zero-flag to the correct value.

Subject: [PATCH 749/906] Remove top-level Clang -fsanitize= flags for optional
 ASan features.

Init-order and use-after-return modes can currently be enabled
by runtime flags. use-after-scope mode is not really working at the
moment.

The only problem I see is that users won't be able to disable extra
instrumentation for init-order and use-after-scope by a top-level Clang flag.
But this instrumentation was implicitly enabled for quite a while and
we didn't hear from users hurt by it.

Subject: [PATCH 750/906] Make the error-handling functions thread-safe.

Prior to this change, error handling functions must be installed
and removed only inside of an llvm_[start/stop]_multithreading
pair.  This change allows error handling functions to be installed
any time, and from any thread.

Subject: [PATCH 751/906] test/DebugInfo/X86/dbg-value-isel.s: correct lexical
 block descriptor to match schema

This silently broke a long time ago when I unified some aspects of the
debug info schema. I'm just cleaning these up if/when they become a
problem.

Subject: [PATCH 752/906] DebugInfo: Refactor some tests to allow DW_AT_name to
 not be the first attribute in a local variable.

In an effort to fix concrete variables referencing abstract origins
where the concrete variable preceeds the first inlined usage, the
addition of attributes such as name, file, etc will be delayed until the
end of the module (to wait to see if any inlined instances have
occurred, thus necessitating an abstract definition that the concrete
definition should also reference).

These test cases don't actually need to care about this ordering of
attributes, so update them to be more resilient to such changes coming
in the near future.

Subject: [PATCH 753/906] DebugInfo: Following up to r209677, refactor local
 variable emission to delay the choice between emitting the definition
 attributes or using DW_AT_abstract_definition

This doesn't fix the abstract variable handling yet, but it introduces a
similar delay mechanism as was added for subprograms, causing
DW_AT_location to be reordered to the beginning of the attribute list
for local variables, and fixes all the test fallout for that.

A subsequent commit will remove the abstract variable handling in
DbgVariable and just do the abstract variable lookup at module end to
ensure that abstract variables introduced after their concrete
counterparts are appropriately referenced by the concrete variable.

Subject: [PATCH 756/906] DebugInfo: Reference abstract definitions from
 variables in concrete definitions that preceed their first inline definition.

Rather than relying on abstract variables looked up at the time the
concrete variable is created, look them up at the end of the module to
ensure they're referenced even if they're created after the concrete
definition. This completes/matches the work done in r209677 to handle
this for the subprograms themselves.

Subject: [PATCH 759/906] Move GlobalMerge from Transform to CodeGen.

This patch is to move GlobalMerge pass from Transform/Scalar
to CodeGen, because GlobalMerge depends on TargetMachine.
In the mean time, the macro INITIALIZE_TM_PASS is also moved
to CodeGen/Passes.h. With this fix we can avoid making
libScalarOpts depend on libCodeGen.

Subject: [PATCH 763/906] DebugInfo: Remove some extra handling of abstract
 variables and instead rely solely on the delayed handling introduced in
 r210946

Now that we handle finding abstract variables at the end of the module,
remove the upfront handling and just ensure the abstract variable is
built when necessary.

In theory we could have a split implementation, where inlined variables
are immediately constructed referencing the abstract definition, and
concrete variables are delayed - but let's go with one solution for now
unless there's a reason not to.

Subject: [PATCH 766/906] R600: Fix asserts related to constant initializers

This would assert if a constant address space was extern
and therefore didn't have an initializer. If the initializer
was undef, it would hit the unreachable unhandled initializer case.

An extern global should never really occur since we don't have
machine linking, but bugpoint likes to remove initializers.

Subject: [PATCH 775/906] AArch64: improve handling & modelling of FP_TO_XINT
 nodes.

There's probably no acatual change in behaviour here, just updating
the LowerFP_TO_INT function to be more similar to the reverse
implementation and updating costs to current CodeGen.

Subject: [PATCH 776/906] LegalizeDAG: make sure cast is unsigned before using
 FP_TO_UINT.

It's valid to use FP_TO_SINT when asking for a smaller type (e.g. all
"unsigned int16" values fit into a "signed int32"), but the reverse
isn't true.

Unfortunately, I'm not actually aware of any architecture with
asymmetric FP_TO_SINT and FP_TO_UINT handling and the logic happens to
work in the symmetric case, so I can't actually write a test for this.

Subject: [PATCH 778/906] PR20038: DebugInfo missing DIEs for some concrete
 variables.

I haven't nailed this down entirely, but this is about as small of a
test case as I can seem to construct and adequately demonstrates the
crasher. I'll continue investigating the root cause/fix(es).

Subject: [PATCH 788/906] Canonicalize addrspacecast ConstExpr between
 different pointer types

As a follow-up to r210375 which canonicalizes addrspacecast
instructions, this patch canonicalizes addrspacecast constant
expressions.

Given clang uses ConstantExpr::getAddrSpaceCast to emit addrspacecast
cosntant expressions, this patch is also a step towards having the
frontend emit canonicalized addrspacecasts.

Piggyback a minor refactor in InstCombineCasts.cpp

Update three affected tests in addrspacecast-alias.ll,
access-non-generic.ll and constant-fold-gep.ll and added one new test in
constant-fold-address-space-pointer.ll

Subject: [PATCH 790/906] [mips][mips64r6] [ls][wd]c2 were re-encoded with
 11-bit signed immediates rather than 16-bit in MIPS32r6/MIPS64r6

Summary:
The error message for the invalid.s cases isn't very helpful. It happens because
there is an instruction with a wider immediate that would have matched if the
NotMips32r6 predicate were true. I have some WIP to improve the message but it
affects most error messages for removed/re-encoded instructions on
MIPS32r6/MIPS64r6 and should therefore be a separate commit.

Depens on D4115

Subject: [PATCH 791/906] [mips] Merge most of the big/little endian checks in
 atomic.ll

Summary:
There is very little difference between the big and little endian cases in
test/CodeGen/Mips/atomic.ll. Merge them together using multiple
FileCheck prefixes.

Depends on D4117

Subject: [PATCH 795/906] [mips][mips64r6] ll, sc, lld, and scd are re-encoded
 on MIPS32r6/MIPS64r6.

Summary:
The linked-load, store-conditional operations have been re-encoded such
that have a 9-bit offset instead of the 16-bit offset they have prior to
MIPS32r6/MIPS64r6.

While implementing this, I noticed that the atomic load/store pseudos always
emit a sign extension using sll and sra. I have improved this to use seb/seh
when they are available (MIPS32r2/MIPS64r2 and above).

Depends on D4118

Subject: [PATCH 796/906] [mips][mips64r6] cl[oz], and dcl[oz] are re-encoded
 in MIPS32r6/MIPS64r6

Summary:
There is no change to the restrictions, just the result register is stored
once in the encoding rather than twice. The rt field is zero in
MIPS32r6/MIPS64r6.

Depends on D4119

Subject: [PATCH 801/906] Fix pr17056.

This makes llvm-nm ignore members that are not sufficiently aligned for
lib/Object to handle.

These archives are invalid. GNU AR is able to handle this, but in general
just warns about broken archive members.

We should probably start warning too, but for now just make sure llvm-nm
exits with an 0.

Subject: [PATCH 802/906] Refactor the disabling of Thumb-1 LDM/STM generation

Originally I switched the LD/ST optimizer off in TargetMachine as it was previously, but Eric has suggested he'd prefer that it be short-circuited in the pass itself.

No functionality change.

Subject: [PATCH 803/906] LowerSwitch: track bounding range for the condition
 tree.

When LowerSwitch transforms a switch instruction into a tree of ifs it
is actually performing a binary search into the various case ranges, to
see if the current value falls into one cases range of values.

So, if we have a program with something like this:

switch (a) {
case 0:
  do0();
  break;
case 1:
  do1();
  break;
case 2:
  do2();
  break;
default:
  break;
}

the code produced is something like this:

  if (a < 1) {
    if (a == 0) {
      do0();
    }
  } else {
    if (a < 2) {
      if (a == 1) {
        do1();
      }
    } else {
      if (a == 2) {
        do2();
      }
    }
  }

This code is inefficient because the check (a == 1) to execute do1() is
not needed.

The reason is that because we already checked that (a >= 1) initially by
checking that also  (a < 2) we basically already inferred that (a == 1)
without the need of an extra basic block spawned to check if actually (a
== 1).

The patch addresses this problem by keeping track of already
checked bounds in the LowerSwitch algorithm, so that when the time
arrives to produce a Leaf Block that checks the equality with the case
value / range the algorithm can decide if that block is really needed
depending on the already checked bounds .

For example, the above with "a = 1" would work like this:

the bounds start as LB: NONE , UB: NONE
as (a < 1) is emitted the bounds for the else path become LB: 1 UB:
NONE. This happens because by failing the test (a < 1) we know that the
value "a" cannot be smaller than 1 if we enter the else branch.
After the emitting the check (a < 2) the bounds in the if branch become
LB: 1 UB: 1. This is because by checking that "a" is smaller than 2 then
the upper bound becomes 2 - 1 = 1.

When it is time to emit the leaf block for "case 1:" we notice that 1
can be squeezed exactly in between the LB and UB, which means that if we
arrived to that block there is no need to emit a block that checks if (a
== 1).

Subject: [PATCH 804/906] Fix illegal relocations in X86FastISel

On x86_86  the lea instruction can only use a 32 bit immediate value. When
the code is compiled statically the RIP register is not used, meaning the
immediate is all that can be used for the relocation, which is not sufficient
in the case of targets more than +/- 2GB away. This patch bails out of fast
isel in those cases and reverts to DAG which does the right thing.

Test case included.

Subject: [PATCH 805/906] ARM: implement correct atomic operations on v7M

ARM v7M has ldrex/strex but not ldrexd/strexd. This means 32-bit
operations should work as normal, but 64-bit ones are almost certainly
doomed.

Patch by Phoebe Buckheister.

 (r210597)

It was pointed out that this breaks the "virtual test discovery"
mechanism, which allows for narming tests in the test exec root.

Reverting until I can figure out how to fix this.

Subject: [PATCH 808/906] Clean up some unnecessary mutex guards.

These were being used as unreferenced parameters to enforce that
the methods must not be called without holding a mutex, but all
of the methods in question were internal, and the methods were
only exposed through an interface whose entire purpose was to
serialize access to these structures, so expecting the methods
to be accessed under a mutex is reasonable enough.

Subject: [PATCH 810/906] [PPC64] Fix PR19893 - improve code generation for
 local function addresses

Rafael opened http://llvm.org/bugs/show_bug.cgi?id=19893 to track non-optimal
code generation for forming a function address that is local to the compile
unit.  The existing code was treating both local and non-local functions
identically.

This patch fixes the problem by properly identifying local functions and
generating the proper addis/addi code.  I also noticed that Rafael's earlier
changes to correct the surrounding code in PPCISelLowering.cpp were also
needed for fast instruction selection in PPCFastISel.cpp, so this patch
fixes that code as well.

The existing test/CodeGen/PowerPC/func-addr.ll is modified to test the new
code generation.  I've added a -O0 run line to test the fast-isel code as
well.

Tested on powerpc64[le]-unknown-linux-gnu with no regressions.

Subject: [PATCH 813/906] Add load/store functionality

Summary:
This patches allows non conversions like i1=i2; where both are global ints.
In addition, arithmetic and other things start to work since fast-isel will use
existing patterns for non fast-isel from tablegen files where applicable.

In addition i8, i16 will work in this limited context for assignment without the need
for sign extension (zero or signed). It does not matter how i8 or i16 are loaded (zero or sign extended)
since only the 8 or 16 relevant bits are used and clang will ask for sign extension before using them in
arithmetic. This is all made more complete in forthcoming patches.

for example:
  int i, j=1, k=3;

  void foo() {
    i = j + k;
  }

Keep in mind that this pass is not enabled right now and is an experimental pass
It can only be enabled with a hidden option to llvm of -mips-fast-isel.

Test Plan: Run test-suite, loadstore2.ll and I will run some executable tests.

-.. _startmultithreaded:
-
-Entering and Exiting Multithreaded Mode
----------------------------------------
-
-In order to properly protect its internal data structures while avoiding
-excessive locking overhead in the single-threaded case, the LLVM must intialize
-certain data structures necessary to provide guards around its internals.  To do
-so, the client program must invoke ``llvm_start_multithreaded()`` before making
-any concurrent LLVM API calls.  To subsequently tear down these structures, use
-the ``llvm_stop_multithreaded()`` call.  You can also use the
-``llvm_is_multithreaded()`` call to check the status of multithreaded mode.
-
-Note that both of these calls must be made *in isolation*.  That is to say that
-no other LLVM API calls may be executing at any time during the execution of
-``llvm_start_multithreaded()`` or ``llvm_stop_multithreaded``.  It is the
-client's responsibility to enforce this isolation.
-
-The return value of ``llvm_start_multithreaded()`` indicates the success or
-failure of the initialization.  Failure typically indicates that your copy of
-LLVM was built without multithreading support, typically because GCC atomic
-intrinsics were not found in your system compiler.  In this case, the LLVM API
-will not be safe for concurrent calls.  However, it *will* be safe for hosting
-threaded applications in the JIT, though :ref:`care must be taken
-<jitthreading>` to ensure that side exits and the like do not accidentally
-result in concurrent LLVM API calls.
-
 .. _shutdown:
 
 Ending Execution with ``llvm_shutdown()``
 -----------------------------------------
 
 When you are done using the LLVM APIs, you should call ``llvm_shutdown()`` to
-deallocate memory used for internal structures.  This will also invoke
-``llvm_stop_multithreaded()`` if LLVM is operating in multithreaded mode.  As
-such, ``llvm_shutdown()`` requires the same isolation guarantees as
-``llvm_stop_multithreaded()``.
-
-Note that, if you use scope-based shutdown, you can use the
-``llvm_shutdown_obj`` class, which calls ``llvm_shutdown()`` in its destructor.
-
+deallocate memory used for internal structures.
 .. _managedstatic:
 
 Lazy Initialization with ``ManagedStatic``
 ------------------------------------------
 
 ``ManagedStatic`` is a utility class in LLVM used to implement static
-initialization of static resources, such as the global type tables.  Before the
-invocation of ``llvm_shutdown()``, it implements a simple lazy initialization
-scheme.  Once ``llvm_start_multithreaded()`` returns, however, it uses
+initialization of static resources, such as the global type tables.  In a
+single-threaded environment, it implements a simple lazy initialization scheme.
+When LLVM is compiled with support for multi-threading, however, it uses
 double-checked locking to implement thread-safe lazy initialization.
 
-Note that, because no other threads are allowed to issue LLVM API calls before
-``llvm_start_multithreaded()`` returns, it is possible to have
-``ManagedStatic``\ s of ``llvm::sys::Mutex``\ s.
-
-The ``llvm_acquire_global_lock()`` and ``llvm_release_global_lock`` APIs provide
-access to the global lock used to implement the double-checked locking for lazy
-initialization.  These should only be used internally to LLVM, and only if you
-know what you're doing!

Subject: [PATCH 819/906] Cleanup more unreferenced MutexGuard parameters on
 functions.

These parameters are intended to serve as sort of a contract that
you cannot access the functions outside of a mutex.  However, the
entire JIT class cannot be accessed outside of a mutex anyway, and
all methods acquire a lock as soon as they are entered.  Since the
containing class already is not intended to be thread-safe, it only
serves to add code clutter.

 using the resultant compiler to build a copy of LLVM with multithreading
 support.
 
+.. _startmultithreaded:
+
+Entering and Exiting Multithreaded Mode
+---------------------------------------
+
+In order to properly protect its internal data structures while avoiding
+excessive locking overhead in the single-threaded case, the LLVM must intialize
+certain data structures necessary to provide guards around its internals.  To do
+so, the client program must invoke ``llvm_start_multithreaded()`` before making
+any concurrent LLVM API calls.  To subsequently tear down these structures, use
+the ``llvm_stop_multithreaded()`` call.  You can also use the
+``llvm_is_multithreaded()`` call to check the status of multithreaded mode.
+
+Note that both of these calls must be made *in isolation*.  That is to say that
+no other LLVM API calls may be executing at any time during the execution of
+``llvm_start_multithreaded()`` or ``llvm_stop_multithreaded``.  It is the
+client's responsibility to enforce this isolation.
+
+The return value of ``llvm_start_multithreaded()`` indicates the success or
+failure of the initialization.  Failure typically indicates that your copy of
+LLVM was built without multithreading support, typically because GCC atomic
+intrinsics were not found in your system compiler.  In this case, the LLVM API
+will not be safe for concurrent calls.  However, it *will* be safe for hosting
+threaded applications in the JIT, though :ref:`care must be taken
+<jitthreading>` to ensure that side exits and the like do not accidentally
+result in concurrent LLVM API calls.
+
 .. _shutdown:
 
 Ending Execution with ``llvm_shutdown()``
 -----------------------------------------
 
 When you are done using the LLVM APIs, you should call ``llvm_shutdown()`` to
-deallocate memory used for internal structures.
+deallocate memory used for internal structures.  This will also invoke
+``llvm_stop_multithreaded()`` if LLVM is operating in multithreaded mode.  As
+such, ``llvm_shutdown()`` requires the same isolation guarantees as
+``llvm_stop_multithreaded()``.
+
+Note that, if you use scope-based shutdown, you can use the
+``llvm_shutdown_obj`` class, which calls ``llvm_shutdown()`` in its destructor.
+
 .. _managedstatic:
 
 Lazy Initialization with ``ManagedStatic``
 ------------------------------------------
 
 ``ManagedStatic`` is a utility class in LLVM used to implement static
-initialization of static resources, such as the global type tables.  In a
-single-threaded environment, it implements a simple lazy initialization scheme.
-When LLVM is compiled with support for multi-threading, however, it uses
+initialization of static resources, such as the global type tables.  Before the
+invocation of ``llvm_shutdown()``, it implements a simple lazy initialization
+scheme.  Once ``llvm_start_multithreaded()`` returns, however, it uses
 double-checked locking to implement thread-safe lazy initialization.
 
+Note that, because no other threads are allowed to issue LLVM API calls before
+``llvm_start_multithreaded()`` returns, it is possible to have
+``ManagedStatic``\ s of ``llvm::sys::Mutex``\ s.
+
+The ``llvm_acquire_global_lock()`` and ``llvm_release_global_lock`` APIs provide
+access to the global lock used to implement the double-checked locking for lazy
+initialization.  These should only be used internally to LLVM, and only if you
+know what you're doing!

Subject: [PATCH 821/906] Teach LoopUnrollPass to respect loop unrolling hints
 in metadata.

[This is resubmitting r210721, which was reverted due to suspected breakage
which turned out to be unrelated].

Some extra review comments were addressed. See D4090 and D4147 for more details.

The Clang change that produces this metadata was committed in r210667

Patch by Mark Heffernan.

Subject: [PATCH 822/906] [FastISel][X86] Refactor the code to get the X86
 condition from a helper function. NFC.

Make use of helper functions to simplify the branch and compare instruction
selection in FastISel. Also add test cases for compare and conditonal branch.

Subject: [PATCH 823/906] Expose ValueMap's mutex type as a typedef instead of
 a sys::Mutex.

This enables static polymorphism of the mutex type, which is
necessary in order to replace the standard mutex implementation
with a different type.

Subject: [PATCH 824/906] SROA: Only split loads on byte boundaries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

r199771 accidently broke the logic that makes sure that SROA only splits
load on byte boundaries.  If such a split happens, some bits get lost
when reassembling loads of wider types, causing data corruption.

Move the width check up to reject such splits early, avoiding the
corruption.  Fixes PR19250.

Patch by: Björn Steinbrink <bsteinbr@gmail.com>

Subject: [PATCH 826/906] [InstCombine] mark ADD with nuw if no unsigned
 overflow

Summary:
As a starting step, we only use one simple heuristic: if the sign bits
of both a and b are zero, we can prove "add a, b" do not unsigned
overflow, and thus convert it to "add nuw a, b".

Updated all affected tests and added two new tests (@zero_sign_bit and
@zero_sign_bit2) in AddOverflow.ll

Test Plan: make check-all

Mimic r116632 in passing LLVM_VERSION_INFO from the Makefile build
system to the build. This improves the -version output of tools that
use llvm::cl under the configure+make system.

Subject: [PATCH 832/906] [msan] Fix handling of multiplication by a constant
 with a number of trailing zeroes.

Multiplication by an integer with a number of trailing zero bits leaves
the same number of lower bits of the result initialized to zero.
This change makes MSan take this into account in the case of multiplication by
a compile-time constant.

We don't handle the general, non-constant, case because
(a) it's not going to be cheap (computation-wise);
(b) multiplication by a partially uninitialized value in user code is
    a bad idea anyway.

Constant case must be handled because it appears from LLVM optimization of a
completely valid user code, as the test case in compiler-rt demonstrates.

Subject: [PATCH 835/906] AArch64: estimate inline asm length during branch
 relaxation

To make sure branches are in range, we need to do a better job of estimating
the length of an inline assembly block than "it's probably 1 instruction, who'd
write asm with more than that?".

Fortunately there's already a (highly suspect, see how many ways you can think
of to break it!) callback for this purpose, which is used by the other targets.

 (r211077)

Overlooked that fcmp_une uses an "or" instead of an "and" for combining the
flags.

Subject: [PATCH 840/906] R600/SI: Re-initialize the m0 register after using it
 for indirect addressing

We need to store a value greater than or equal to the number of LDS
bytes allocated by the shader in the m0 register in order for LDS
instructions to work correctly.

We always initialize m0 at the beginning of a shader, but this register
is also used for indirect addressing offsets, so we need to
re-initialize it any time we use indirect addressing.

Subject: [PATCH 844/906] mark the old jit tests as unsupported for powerpc64
 (for cmake)

mark the old JIT tests as unsupported for powerpc64 - CMake style.
This follows the style used for hexagon/arm64/aarch64.
The equivalent tests still run under the supported MCJIT/*

Like System V format, there are also some small changes in how and where
the file names and archive member names are printed for darwin and
Mach-O.

possible to make llvm-size produce the same output as darwin's size(1).

Subject: [PATCH 848/906] Merge lib/Support/WindowsError.cpp into
 ib/Support/ErrorHandling.cpp.

The OSX ranlib warns on files with no symbols, and lib/Support/WindowsError.cpp
was empty when building on non-windows.

Subject: [PATCH 851/906] Remove more occurrences of the unused-mutex-parameter
 pattern.

This pattern loses some of its usefulness when the mutex type is
statically polymorphic as opposed to runtime polymorphic, as
swapping out the mutex type requires changing a significant number
of function parameters, and templatizing the function parameter
requires the methods to be defined in the headers.

Furthermore, if LLVM is compiled with threads disabled then there
may even be no mutex to acquire anyway, so it should not be up to
individual APIs to know whether or not acquiring a mutex is required
to use those APIs to begin with.  It should be up to the user of the
API.

Subject: [PATCH 852/906] [FastISel][X86] Optimize predicates and fold CMP
 instructions.

This optimizes predicates for certain compares, such as fcmp oeq %x, %x to
fcmp ord %x, %x. The latter one is more efficient to generate.

The same optimization is applied to conditional branches.

Subject: [PATCH 853/906] Allow X86FastIsel to cope with 64 bit absolute
 relocations

This patch is a follow up to r211040 & r211052. Rather than bailing out of fast
isel this patch will generate an alternate instruction (movabsq) instead of the
leaq. While this will always have enough room to handle the 64 bit displacment
it is generally over kill for internal symbols (most displacements will be
within 32 bits) but since we have no way of communicating the code model to the
the assmebler in order to avoid flagging an absolute leal/leaq as illegal when
using a symbolic displacement.

Subject: [PATCH 856/906] [AArch64] Fix a pattern match failure caused by
 creating improper CONCAT_VECTOR.

ReconstructShuffle() may wrongly creat a CONCAT_VECTOR trying to
concat 2 of v2i32 into v4i16. This commit is to fix this issue and
try to generate UZP1 instead of lots of MOV and INS.
Patch is initalized by Kevin Qin, and refactored by Tim Northover.

Subject: [PATCH 857/906] Random Number Generator (llvm)

Summary:
Provides an abstraction for a random number generator (RNG) that produces a stream of pseudo-random numbers.
The current implementation uses C++11 facilities and is therefore not cryptographically secure.

The RNG is salted with the text of the current command line invocation.
In addition, a user may specify a seed (reproducible builds).

In clang, the seed can be set via

Subject: [PATCH 862/906] DAG: move sret demotion into most basic LowerCallTo
 implementation.

It looks like there are two versions of LowerCallTo here: the
SelectionDAGBuilder one is designed to operate on LLVM IR, and the
TargetLowering one in the case where everything is at DAG level.

Previously, only the SelectionDAGBuilder variant could handle demoting
an impossible return to sret semantics (before delegating to the
TargetLowering version), but this functionality is also useful for
certain libcalls (e.g. 128-bit operations on 32-bit x86).  So this
commit moves the sret handling down a level.

rdar://problem/17242889

Subject: [PATCH 871/906] [mips] Access $at only if necessary.

Summary:
This patch doesn't really change the logic behind expandMemInst but it allows
us to assemble .S files that use .set noat with some macros. For example:

.set noat
lw $k0, offset($k1)

Can expand to:
lui	$k0, %hi(offset)
addu	$k0, $k0, $k1
lw	$k0, %lo(offset)($k0)

with no need to access $at.

Subject: [PATCH 874/906] [mips] Fix expansion of memory operation if
 destination register is not a GPR.

Summary:
The assembler tries to reuse the destination register for memory operations whenever
it can but it's not possible to do so if the destination register is not a GPR.

Example:
  ldc1 $f0, sym
should expand to:
  lui $at, %hi(sym)
  ldc1 $f0, %lo(sym)($at)

It's entirely wrong to expand to:
  lui $f0, %hi(sym)
  ldc1 $f0, %lo(sym)($f0)

Subject: [PATCH 876/906] [PowerPC] Fix emitting instruction pairs on LE

My patch r204634 to emit instructions in little-endian format failed to
handle those special cases where we emit a pair of instructions from a
single LLVM MC instructions (like the bl; nop pairs used to implement
the call sequence).

In those cases, we still need to emit the "first" instruction (the one
in the more significant word) first, on both big and little endian,
and not swap them.

Subject: [PATCH 877/906] Do not XFAIL test/tools/llvm-cov tests on powerpc64le

All tests in test/tools/llvm-cov fail on big-endian targets and are
supposed to be XFAILed there.  However, including "powerpc64" in the
XFAIL line is now incorrect, since that matches both powerpc64- and
powerpc64le- targets, and the tests pass on the latter.

Update the XFAIL lines to use powerpc64- instead (like mips64-).

Subject: [PATCH 878/906] [PowerPC] Do not use BLA with the 64-bit SVR4 ABI

The PowerPC back-end uses BLA to implement calls to functions at
known-constant addresses, which is apparently used for certain
system routines on Darwin.

However, with the 64-bit SVR4 ABI, this is actually incorrect.
An immediate function pointer value on this platform is not
directly usable as a target address for BLA:
- in the ELFv1 ABI, the function pointer value refers to the
  *function descriptor*, not the code address
- in the ELFv2 ABI, the function pointer value refers to the
  global entry point, but BL(A) would only be correct when
  calling the *local* entry point

This bug didn't show up since using immediate function pointer
values is not usually done in the 64-bit SVR4 ABI in the first
place.  However, I ran into this issue with a certain use case
of LLVM as JIT, where immediate function pointer values were
uses to implement callbacks from JITted code to helpers in
statically compiled code.

Fixed by simply not using BLA with the 64-bit SVR4 ABI.

Subject: [PATCH 884/906] R600: Implement f64 ftrunc, ffloor and fceil.

CI has instructions for these, so this fixes them for older hardware.

Subject: [PATCH 890/906] [PowerPC] Add back test case for absolute calls
 (removed in r211174)

As requested by Hal Finkel, this adds back a test for calls to
a known-constant function pointer value, and verifies that the
64-bit SVR4 indirect function call sequence is used.

Subject: [PATCH 892/906] [PowerPC] Simplify and improve loading into TOC
 register

During an indirect function call sequence on the 64-bit SVR4 ABI,
generate code must load and then restore the TOC register.

This does not use a regular LOAD instruction since the TOC
register r2 is marked as reserved.  Instead, the are two
special instruction patterns:

 let RST = 2, DS = 2 in
 def LDinto_toc: DSForm_1a<58, 0, (outs), (ins g8rc:$reg),
                     "ld 2, 8($reg)", IIC_LdStLD,
                     [(PPCload_toc i64:$reg)]>, isPPC64;

 let RST = 2, DS = 10, RA = 1 in
 def LDtoc_restore : DSForm_1a<58, 0, (outs), (ins),
                     "ld 2, 40(1)", IIC_LdStLD,
                     [(PPCtoc_restore)]>, isPPC64;

Note that these not only restrict the destination of the
load to r2, but they also restrict the *source* of the
load to particular address combinations.  The latter is
a problem when we want to support the ELFv2 ABI, since
there the TOC save slot is no longer at 40(1).

This patch replaces those two instructions with a single
instruction pattern that only hard-codes r2 as destination,
but supports generic addresses as source.  This will allow
supporting the ELFv2 ABI, and also helps generate more
efficient code for calls to absolute addresses (allowing
simplification of the ppc64-calls.ll test case).

Subject: [PATCH 895/906] [ARM] [MC] Refactor the constant pool classes

ARMTargetStreamer implements ConstantPool and AssmeblerConstantPools
to keep track of assembler-generated constant pools that are used for
ldr-pseudo.

When implementing ldr-pseudo for AArch64, these two classes can be reused.
So this patch factors them out from ARM target to the general MC lib.

Subject: [PATCH 899/906] [PowerPC] Remove unnecessary load of r12 in indirect
 call

When looking at the 64-bit SVR4 indirect call sequence, I noticed
an unnecessary load of r12.  And indeed the code says:

  // R12 must contain the address of an indirect callee.

But this is not correct; in the 64-bit SVR4 (ELFv1) ABI, there is
no need to load r12 at this point.  It seems this code and comment
is a remnant of code originally shared with the Darwin ABI ...

This patch simply removes the unnecessary load.

Subject: [PATCH 900/906] Simply test for available locations in optimization
 remarks.

When emitting optimization remarks, we test for the presence of
instruction locations by testing for a valid llvm.dbg.cu annotation.
This is slightly inefficient because we can simply ask whether the
debug location we have is known or not.

Additionally, if my current plan works, I will need to remove the
llvm.dbg.cu annotation from the IL (or prevent it from being generated)
when -Rpass is used without -g.  In those cases, we'll want to generate
line tables but we will want to prevent code generation from emitting
DWARF code for them.

Tested on x86_64.

Subject: [PATCH 901/906] Remove BitcodeReader::setBufferOwned.

We do have use cases for the bitcode reader owning the buffer or not, but we
always know which one we have when we construct it.

It might be possible to simplify this further, but this is a step in the
right direction.

Subject: [PATCH 902/906] Change IRObjectFile to parse the bitcode lazily.

The main point of this class is to provide a cheap object interface to a bitcode
file, so it has to be as lazy as possible.

LLVMGetBitcodeModuleInContext should not take ownership on error. I will
try to localize this odd api requirement, but this should get the bots green.

Subject: [PATCH 906/906] Fixes SjLj preparation step on iOS

Rust uses a lot of empty structs internally. That caused problems during SjLj preparation step as it expected that every function argument actually has some data in it which should be either copied/bitcasted.

This fix simply skips any action for arguments which have no data inside (structs with zero fields or arrays with zero elements)
