[X86] Missing vector support for ISD::FP_TO_SINT_SAT/FP_TO_UINT_SAT #64062

Closed RKSimon closed 1 year ago

RKSimon commented 1 year ago

As noted on https://reviews.llvm.org/D154841 we only have scalar support for FP_TO_SINT_SAT/FP_TO_UINT_SAT, although we should be able to use the CVTTPD2DQ/CVTTPS2DQ special cases in the same way that we do for scalars already.

There is already an issue for it: https://github.com/llvm/llvm-project/issues/51923 I have a draft for it https://reviews.llvm.org/D150372

Thanks @e-kud - looks like I've already reported this :)
