[PATCH] D89390: [TargetLowering] Update optimization to check for boolean content

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

Looks like we have a couple of in-tree targets where this will make a difference, so we should add a test.

Try something like this with -mtriple=nvptx ?

  define i32 @pow2_mask_cmp(i32 %x) {
    %a = and i32 %x, 8
    %cmp = icmp ne i32 %a, 0
    %r = zext i1 %cmp to i32
    ret i32 %r
  }
