* [AMDGPU] New 64 bit div/rem expansionStanislav Mekhanoshin2017-10-061-67/+13
| | | | | | | | | | | Old expansion was 20 VGPRs, 78 SGPRs and ~380 instructions. This expansion is 11 VGPRs, 12 SGPRs and ~120 instructions. Passes OpenCL conformance test_integer_ops quick_[u]long_math Differential Revision: https://reviews.llvm.org/D38607 llvm-svn: 315081
* AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernelMatt Arsenault2017-03-211-6/+6
| | | | | | | | | | | | 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
* Enable FeatureFlatForGlobal on Volcanic IslandsMatt Arsenault2017-01-241-1/+1
| | | | | | | | | | | 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: Fold bitcasts of scalar constants to vectorsMatt Arsenault2016-04-141-39/+39
| | | | | | | This cleans up some messes since the individual scalar components can be CSEed. llvm-svn: 266376
