[PATCH] D81327: [X86] Teach combineBitcastvxi1 to prefer movmsk on avx512 in more cases

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/test/CodeGen/X86/avx512bwvl-intrinsics-upgrade.ll:6410
 ; CHECK-NEXT:    ret{{[l|q]}} # encoding: [0xc3]
     %res = call i16 @llvm.x86.avx512.cvtb2mask.128(<16 x i8> %x0)
     ret i16 %res
----------------
I don't recognise what (c/c++) intrinsic this would have come from - is this likely to be a problem? Same for the other *-intrinsics-upgrade.ll cases
