Michael Liao	6883d7e192	[AMDGPU] Fix SGPR fixing through SCC chaining ... Summary: - During the fixing of SGPR copying from VGPR, ensure users of SCC is properly propagated, i.e. * only propagate through live def of SCC, * skip the SCC-def inst itself, and * stop the propagation on the other SCC-def inst after checking its SCC-use first.

Stanislav Mekhanoshin	de42c29a68	[AMDGPU] New 64 bit div/rem expansion ... Old expansion was 20 VGPRs, 78 SGPRs and ~380 instructions. This expansion is 11 VGPRs, 12 SGPRs and ~120 instructions.

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
Matt Arsenault	81a709503d	AMDGPU: Fix high bits after division optimization ... This is essentially doing a 24-bit signed division with FP. We need to truncate to the N bit result. llvm-svn: 270305	2016-05-21 01:53:33 +00:00
