[PATCH] D150790: [GlobalIsel][X86] fix legalization of G_CTLZ and GTCTPOP

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Target/X86/X86LegalizerInfo.cpp:305
+      .clampScalar(1, s16, s64);
+  }
+
----------------
We need to split this - with just s64 legality here  and s16/s32 in setLegalizerInfo32bit above

And just widen sub 32 cases to s32
