[PATCH] D38906: AMDGPU/SI: Implement d16 support for buffer intrinsics

[Changpeng Fang via Phabricator via llvm-commits]

cfang updated this revision to Diff 121560.
cfang retitled this revision from "AMDGPU/SI: Implement d16 support buffer_load_format and tbuffer_load_format intrinsics" to "AMDGPU/SI: Implement d16 support for buffer intrinsics".
cfang added a comment.

1. Define a new feature, HasPackedD16VMem for gfx8.1 and beyond to guard the generation of VMem instructions with https://reviews.llvm.org/D16 bit set.
2. Put buffer_store intrinsics implementation in the same patch as buffer_loads;
