[Mesa-dev] [PATCH 12/15] ac: add support for SPV_AMD_shader_ballot

2017-08-07 Thread Connor Abbott
From: Connor Abbott Using the new WWM and DPP intrinsics introduced in LLVM 6.0. This adds everything needed to implement SPV_AMD_shader_ballot, including the Groups capability, to ac_llvm_build.c. That way, it can be shared by a potential GL_AMD_shader_ballot implementation in the future. Curren
