* [AMDGPU] Convert rcp to rcp_iflagStanislav Mekhanoshin2018-06-271-9/+9
| | | | | | | | | | | If a source of rcp instruction is a result of any conversion from an integer convert it into rcp_iflag instruction. No FP exception can ever happen except division by zero if a single precision rcp argument is a representation of an integral number. Differential Revision: https://reviews.llvm.org/D48569 llvm-svn: 335742
* AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernelMatt Arsenault2017-03-211-17/+17
| | | | | | | | | | | | 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: Fix high bits after division optimizationMatt Arsenault2016-05-211-13/+111
| | | | | | | This is essentially doing a 24-bit signed division with FP. We need to truncate to the N bit result. llvm-svn: 270305
