Changpeng Fang	391bcf8893	AMDGPU/SI: Handle infinite loop for the structurizer to work with CFG with infinite loops. ... Summary: The current StructurizeCFG pass only works for CFG with one exit. AMDGPUUnifyDivergentExitNodes combines multiple "return" blocks and/or "unreachable" blocks to one exit block for the Structurizer to work. However, infinite loop is another kind of special "exit", and if we don't handle it, the case of multiple exits will prevent the structurizer from working. In this work, for each infinite loop, we add a dummy edge to the "return" block, and thus the AMDGPUUnifyDivergentExitNodes pass will work with infinite loops. This will make CFG with infinite loops be structurized. Reviewer: nhaehnle Differential Revision: https://reviews.llvm.org/D46340 llvm-svn: 332625	2018-05-17 16:45:01 +00:00
Mark Searles	70359ac60d	[AMDGPU] Turn on the new waitcnt insertion pass. Adjust tests. ... -enable-si-insert-waitcnts=1 becomes the default -enable-si-insert-waitcnts=0 to use old pass Differential Revision: https://reviews.llvm.org/D33730 llvm-svn: 304551	2017-06-02 14:19:25 +00:00
Matt Arsenault	3dbeefa978	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	2017-03-21 21:39:51 +00:00
Matt Arsenault	7aad8fd8f4	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	2017-01-24 22:02:15 +00:00
