Extended Description

While compiling mplayer with clang, I get:

libmpcodecs/vf_fspp.c:1591:41: error: invalid output constraint '=o' in asm
: "+S"(data), "+D"(output), "+c"(cnt), "=o"(temps)

...
------>"movq %%mm1, "DCTSIZE_S"32(%%"REG_D") \n\t"
<------>"add $24, %%"REG_D" \n\t"
<------>"sub $2, %%"REG_c" \n\t"
<------>"jnz 1b \n\t"
<------>"5: \n\t"

<------>: "+S"(data), "+D"(output), "+c"(cnt), "=o"(temps)
<------>: "d"(thr_adr)
<------>: "%"REG_a

I think someone implemented this recently.

I'm still seeing this with:
clang version 2.0 (trunk 104456)

libmpcodecs/vf_fspp.c:1597:41: error: invalid output constraint '=o' in asm
: "+S"(data), "+D"(output), "+c"(cnt), "=o"(temps)

Dale, can you take a look at this?

I recently fixed some missing X86-specific constraints, but this is generic. Fixed in 113246.
