[PATCH] D57748: AMDGPU: Add inverse ballot intrinsic

[Connor Abbott via Phabricator via llvm-commits]

cwabbott updated this revision to Diff 185317.
cwabbott added a comment.

- Added a pseudoinstruction lowered in SILowerI1Copies, and legalized it more

similarly to how other instructions are legalized.

- Added tests where the source is a uniform and non-uniform phi node. I had to

to use the amdgpu_ps calling convention here to get the arguments into SGPR's.
