* AMDGPU: Remove some uses of llvm.SI.export in testsMatt Arsenault2017-02-221-3/+5
| | | | | | Merge some of the old, smaller tests into more complete versions. llvm-svn: 295792
* Enable FeatureFlatForGlobal on Volcanic IslandsMatt Arsenault2017-01-241-7/+7
| | | | | | | | | | | 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/SI: Increase SGPR limit to 96 on Tonga/IcelandMarek Olsak2016-08-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is the setting of the Vulkan closed source driver. It decreases the max wave count from 10 to 8. 26010 shaders in 14650 tests Totals: VGPRS: 829593 -> 808440 (-2.55 %) Spilled SGPRs: 81878 -> 42226 (-48.43 %) Spilled VGPRs: 367 -> 358 (-2.45 %) Scratch VGPRs: 1764 -> 1748 (-0.91 %) dwords per thread Code Size: 36677864 -> 35923932 (-2.06 %) bytes There is a massive decrease in SGPR spilling in general and -7.4% spilled VGPRs for DiRT Showdown (= SGPRs spilled to scratch?)

* AMDGPU: Add a shader calling conventionNicolai Haehnle2016-04-061-3/+1
| | | | | | | | | | | This makes it possible to distinguish between mesa shaders and other kernels even in the presence of compute shaders. Patch By: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl> Differential Revision: http://reviews.llvm.org/D18559 llvm-svn: 265589
* [MC] Use .p2align instead of .alignDan Gohman2016-01-261-1/+1
| | | | | | | | | | | | | | | For historic reasons, the behavior of .align differs between targets. Fortunately, there are alternatives, .p2align and .balign, which make the interpretation of the parameter explicit, and which behave consistently across targets. This patch teaches MC to use .p2align instead of .align, so that people reading code for multiple architectures don't have to remember which way each platform does its .align directive.
