[SDA] Don't stop divergence propagation at the IPD.

2019-09-18T13:40:22+00:00

Summary: This fixes B42473 and B42706. This patch makes the SDA propagate branch divergence until the end of the RPO traversal. Before, the SyncDependenceAnalysis propagated divergence only until the IPD in rpo order. RPO is incompatible with post dominance in the presence of loops. This made the SDA crash because blocks were missed in the propagation.

[AMDGPU] ImmArg and SourceOfDivergence for permlane/dpp

2019-06-13T16:31:51+00:00

Added missing ImmArg and SourceOfDivergence to the crosslane intrinsics. Differential Revision: https://reviews.llvm.org/D63216 llvm-svn: 363276

[SDA] Bug fix: Use IPD outside the loop as divergence bound

2019-04-18T16:17:35+00:00

Summary: The immediate post dominator of the loop header may be part of the divergent loop. Since this /was/ the divergence propagation bound the SDA would not detect joins of divergent paths outside the loop.

[AMDGPU] Add support for 64 bit buffer atomic artihmetic instructions

2019-03-06T17:02:06+00:00

Summary: This adds support for 64 bit buffer atomic arithmetic instructions but does not include cmpswap as that depends on a fix to the way the register pairs are handled Change-Id: Ib207ea65fb69487ccad5066ea647ae8ddfe2ce61 Subscribers: arsenm, kzhuravl, jvesely, wdng, nhaehnle, yaxunl, dstuttard, tpr, t-tye, jfb, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D58918 llvm-svn: 355520

[AMDGPU] Add intrinsics for 16 bit interpolation

2019-01-28T13:48:59+00:00

Summary: Added the intrinsics llvm.amdgcn.interp.p1.f16() and llvm.amdgcn.interp.p2.f16() and related LIT test. The p1 intrinsic generates code appropriate for both 16 and 32 bank LDS.

[AMDGPU] Add some missing always-uniform values.

[DA] GPUDivergenceAnalysis for unstructured GPU kernels

2018-11-30T22:55:20+00:00

Summary: This is patch #3 of the new DivergenceAnalysis The GPUDivergenceAnalysis is intended to eventually supersede the existing LegacyDivergenceAnalysis. The existing LegacyDivergenceAnalysis produces incorrect results on unstructured Control-Flow Graphs: This patch adds the option -use-gpu-divergence-analysis to the LegacyDivergenceAnalysis to turn it into a transparent wrapper for the GPUDivergenceAnalysis.

[NFC] Rename the DivergenceAnalysis to LegacyDivergenceAnalysis

2018-08-30T14:21:36+00:00

Summary: This is patch 1 of the new DivergenceAnalysis (https://reviews.llvm.org/D50433). The purpose of this patch is to free up the name DivergenceAnalysis for the new generic implementation. The generic implementation class will be shared by specialized divergence analysis classes.
