* AMDGPU: Stop checking intrinsics not used by HSA for dispatch-ptrMatt Arsenault2016-01-301-7/+1
| | | | | | | | Only the dispatch.ptr intrinsic is supposed to be used now to get the workgroup size, and the read.local.size intrinsics do not work correctly. llvm-svn: 259296
* AMDGPU: Add pass to detect used kernel featuresMatt Arsenault2015-11-061-0/+193
Mark kernels that use certain features that require user SGPRs to support with kernel attributes. We need to know before instruction selection begins because it impacts the kernel calling convention lowering. For now this only detects the workitem intrinsics. llvm-svn: 252323
