AMDGPU: Remove some uses of llvm.SI.export in tests Merge some of the old, smaller tests into more complete versions. llvm-svn: 295792
2017-02-22 08:02:21 +08:00
; RUN: llc -march=amdgcn -mcpu=verde -verify-machineinstrs < %s | FileCheck -check-prefix=GCN -check-prefix=SI %s
Enable FeatureFlatForGlobal on Volcanic Islands This switches to the workaround that HSA defaults to for the mesa path. This should be applied to the 4.0 branch. Patch by Vedran Miletić <vedran@miletic.net> llvm-svn: 292982

AMDGPU/SI: Add llvm.amdgcn.mbcnt.* intrinsics Summary: These are meant to be used instead of the llvm.SI.tid intrinsic which will be deprecated at some point. Reviewers: arsenm Subscribers: arsenm, llvm-commits Differential Revision: http://reviews.llvm.org/D15475 llvm-svn: 255652
