[PATCH] D82087: AMDGPU/clang: Add builtins for llvm.amdgcn.ballot

[Jon Chesterfield via Phabricator via cfe-commits]

JonChesterfield added a comment.

A macro for wavefront size would make targeting gfx10 for openmp easier.

We currently use an int32_t for nvptx and an int64_t for amdgcn in various runtime function interfaces. I'd like to be able to set the latter based on said macro.
