[PATCH] D150755: [GlobalIsel][x86] Legalize G_CTPOP and G_CTLZ II

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Target/X86/X86LegalizerInfo.cpp:389
+void X86LegalizerInfo::setLegalizerInfoSSE42() {
+  if (!Subtarget.hasSSE42())
+    return;
----------------
This isn't correct - CTPOP/LZCNT support is provided by Subtarget.hasPOPCNT/hasLZCNT respectively
