[X86] Enable STRICT_SINT_TO_FP/STRICT_UINT_TO_FP on X86 backend

Summary

Enable STRICT_SINT_TO_FP/STRICT_UINT_TO_FP on X86 backend

Is a for loop needed here? Isn’t there only one non chain operand?

571

If the loop is needed I’d use a continue instead of incrementing j. Or handle it outside the loop and start the loop at 1 for strict.

(On Diff #235264)

Do not change this. Normal FP_ROUND has a special case for equal types to skip creating the node. We can’t do that for strict because we can’t manage the chain here. The caller needs to avoid calling getNode when the types are equal.

llvm/lib/Target/X86/X86ISelLowering.cpp

18896

The chain result from this isn’t used. You probably need a token factor somewhere

18897

Use getValue

18905

Use merge values don’t do your own replacement

19008

Can the low bit cast be moved up and shared by both paths?

19011

getValue

19012

Merge values

43804

The chain result isn’t being returned or connected

What change caused these test changes? It looks like most of this patch is vector related. What did I miss?

[pengfei]

Address review comments.

llvm/lib/CodeGen/SelectionDAG/LegalizeVectorOps.cpp

568

It has no difference between strict and normal node. Removed.

llvm/test/CodeGen/X86/fp-intrinsics.ll

2204

The target combine for the node STRICT_SINT_TO_FP/STRICT_UINT_TO_FP.

[pengfei]

Minor fixup.
