[RISCV] Add isel patterns for vfmacc, vfnmacc, vfmsac and vfnmsac.

[fakepaper56]

Summary

The patch selects VSELECT_VL/VP_MERGE_VL that uses VF(N)M(ACC|SAC) as its
true operand and the adden of the true operand as its false operand.

What about the VFMSAC, etc.? You can do them in a separate patch if you want but please give a roadmap of other patches you're planning.

This is also valid for integer vmacc and vnmsac.

Sure, I will add VFMSAC in this patch. And I will add another patch for vmccc and vnmsac.

I think VPatFPMulAccVL_VV_VF could serve VFNMSAC but not VFMSAC, since VFMSAC uses negative of adden.

1418

Maybe I need to use a new opcode riscv_vfmadd_vl_oneuse to make sure the fma instruction is only used by vselect_vl or vp_merge_vl.

Yes

1418

I think it should still be valid for VFMSAC. The elements that are masked off or in the tail won't be negated. The other elements will be.

[fakepaper56]

Add vfnmsac patterns and constarin the selected VFMADD/VFNMSAC should have exactly one user.
Is it OK that I plan to add VFNMADD/VFMSAC in a seperated patch?

[fakepaper56]

Refine commit message.

Yeah, I got the idea. But I just express that VFMAC needs other patterns than VPatFPMulAccVL_VV_VF.

[craig.topper]

llvm/lib/Target/RISCV/RISCVInstrInfoVVLPatterns.td

1418

Why does it need a different pattern?

[fakepaper56]

llvm/lib/Target/RISCV/RISCVInstrInfoVVLPatterns.td

1418

Sorry, I found that I were wrong. I will add VFMSAC and VFNMADD in the revision.

[fakepaper56]

Add patterns for vfmsac, vfnmacc.
