The new X86 shuffle lowering can do just fine without transforming vselects into vector_shuffles. It looks like the only thing this code does right now is cause trouble - in particular, it can lead to combine/legalization infinite loops. Note that it's not completely NFC, since some of the shuffle masks get inverted, which may cause slight differences further down the line. We may want to find a way to invert those masks, but that's orthogonal to this commit. This fixes the hang in PR27689. llvm-svn: 269676 |
