AMDGPU: Promote alloca should skip volatiles llvm-svn: 264214

AMDGPU/SI: Don't promote to vector if the load/store is volatile. Summary: We should not change volatile loads/stores in promoting alloca to vector. Reviewers: arsenm Differential Revision: http://reviews.llvm.org/D33107 llvm-svn: 302943
2017-05-13 04:31:12 +08:00

Fix some broken CHECK lines. The colon is important. llvm-svn: 292761

AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel Currently the default C calling convention functions are treated the same as compute kernels. Make this explicit so the default calling convention can be changed to a non-kernel. Converted with perl -pi -e 's/define void/define amdgpu_kernel void/' on the relevant test directories (and undoing in one place that actually wanted a non-kernel). llvm-svn: 298444
