Matt Arsenault	bcaaea3448	AMDGPU: Stop checking intrinsics not used by HSA for dispatch-ptr ... 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	2016-01-30 05:10:59 +00:00
Matt Arsenault	2f96fe904d	AMDGPU: Add new amdgcn workitem intrinsics ... These use the correct prefix and follow the HSA naming convention rather than the config register option names. llvm-svn: 259293	2016-01-30 04:25:19 +00:00
Tom Stellard	eb7e999b29	AMDGPU: Add llvm.amdgcn.dispatch.ptr intrinsic ... Summary: This returns a pointer to the dispatch packet, which can be used to load information about the kernel dispach. Reviewers: arsenm Subscribers: arsenm, llvm-commits Differential Revision: http://reviews.llvm.org/D14898 llvm-svn: 254116	2015-11-26 00:43:29 +00:00
Matt Arsenault	275274c0fe	AMDGPU: Add pass to detect used kernel features ... 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	2015-11-06 18:01:57 +00:00
