There was a problem hiding this comment.
the signed-unsigned fusion with control bit is a bit ugly, would have been nicer to have separate signed and unsigned variants with the types changed. I suppose this was already the mistake made with the gfx11 builtins though

Can we switch new bf16 types to use the natural __bf16?

Updated to bfloat but GlobalISel does not handle it properly yet. Should we use i16 for now until we update GlobalISel?

Why is this using any_Ty? Should just be the one?

Sizes are halved. GFX11 basically contained same matrix twice.
This is how intrinsics look like at the moment:
gfx11:
declare <16 x i16> @llvm.amdgcn.wmma.bf16.16x16x16.bf16(<16 x i16>, <16 x i16> , <16 x i16>, i1 immarg)
gfx12:
declare <8 x bfloat> @llvm.amdgcn.wmma.bf16.16x16x16.bf16(<8 x bfloat>, <8 x bfloat>, <8 x bfloat>, i1 immarg)

This is kind of horrible. It's not at all clear you're supposed to use one type for one target and a different one for another. I wonder if they should just be renamed?
There was a problem hiding this comment.
I suggest we take a step back, and push the previous version of the patch where the bf16 intrinsics used i16 for consistency with gfx11.
Then, in a follow-up commit we will add new bf16 intrinsics with the proper bfloat type (I realize the naming could be contentious, but we could discuss it in the follow-up review).
