[AArch64]SME2 Outer Product and Accumulate instructions

[CarolineConcatto]

Summary

This patch adds the assembly/disassembly for the following instructions:

BMOPA: Bitwise exclusive NOR population count outer product and accumulate.
BMOPS: Bitwise exclusive NOR population count outer product and subtract.

SMOPA (2-way): Signed integer sum of outer products and accumulate.
SMOPS (2-way): Signed integer sum of outer products and subtract.

UMOPA (2-way): Unsigned integer sum of outer products and accumulate.
UMOPS (2-way): Signed integer sum of outer products and accumulate.

I'm only really bothered about the instruction names. My other suggestions are nice to have but only if you agree they'll make things better.

llvm/lib/Target/AArch64/AArch64SMEInstrInfo.td

Should this be BMOPA_MPPZZ_S because it uses ZA not ZT0?

567

The equivalent SME1 instruction is SMOPA_MPPZZ_S so I'd expect this to be named similar but much like with the DOT instructions you'll need to rename the original to reflect the difference between 4way and 2way. So the original becomes SMOPA_MPPZZ_BtoS and SMOPA_MPPZZ_HtoD and this new one becomes SMOPA_MPPZZ_HtoS. Do you agree?

llvm/lib/Target/AArch64/SMEInstrFormats.td

Up to you but given the change perhaps bit u0, bit u1, bit S is better expressed as a 3bit opcode? It seems weird seeing opc{2}, opc{1}, opc{0}. I'm almost tempted to suggest all the operands are just a 5 bit opcode but I'll leave it up to you if you want to make such a change.

148

Again it's up to you but this just looks like a 3bit opcode to me.

Now, I am not sure if we should do the same for BMOPA.
In sme1 BFMOPA do not have a size, but FMOPA_MPPZZ has(but because it has a D and S size)

567

I had changed for SME1, but these instructions name are in use in AArch64ISelLowering.
So I did not changed for sme1, but did for sme2.
TBH I don't know what is more consistent, changing or not changing the names for sme2.

[paulwalker-arm]

I still want BMOPA_MPPZZ/BMOPS_MPPZZ to include an element suffix but otherwise looks good.

llvm/lib/Target/AArch64/AArch64SMEInstrInfo.td

564

Most all instructions have a size. It is just that some only support a single element type. In such cases we should still add the size suffix so _S in this case because otherwise if a new variant of bmopa is added later we'll be forced to have to rename stuff, much like with the smopa discussion.

567

We should change the old names to be consistent. It doesn't matter that they are used by AArch64ISelLowering because it's just a textual change. It's not that the old names were wrong when originally added, but based on these new SME2 instructions the old names will lead to confusion, hence the new _HtoS style for such things.

With all that said, this assembler work is more important so feel free to defer that refactoring until the assembler support is complete.

Thank you Paul, I will create a to do for that.

Hi @CarolineConcatto, your change seems to be causing a test failure, can you take a look and revert if it will take a while to resolve?
https://lab.llvm.org/buildbot/#/builders/188/builds/21487

Note, the same test also failed in the pre-commit check builds: https://reviews.llvm.org/B194938

[nathanchance]

I just bisected check-llvm failing to this change. Based on that and the above comment and the fact that it does not look like there is any progress on a forward fix that I can see (presumably due to time zones), I reverted this change in 23c50432fb25775fe0eb958bc8c2a099b0a0c286.
