from Andy Furniss
fixed by llvm commit commit d3adac51fcce66e8c79b77299fef9e5f6c4c646e Author: Tom Stellard <thomas.stellard@amd.com> Date: Wed Mar 30 16:35:09 2016 +0000 AMDGPU/SI: Enable lanemask tracking in misched Summary: This results in higher register usage, but should make it easier for the compiler to hide latency. This pass is a prerequisite for some more scheduler improvements, and I think the increase register usage with this patch is acceptable, because when combined with the scheduler improvements, the total register usage will decrease. shader-db stats: 2382 shaders in 478 tests Totals: SGPRS: 48672 -> 49088 (0.85 %) VGPRS: 34148 -> 34847 (2.05 %) Code Size: 1285816 -> 1289128 (0.26 %) bytes LDS: 28 -> 28 (0.00 %) blocks Scratch: 492544 -> 573440 (16.42 %) bytes per wave Max Waves: 6856 -> 6846 (-0.15 %) Wait states: 0 -> 0 (0.00 %) Depends on D18451 Reviewers: nhaehnle, arsenm Subscribers: arsenm, llvm-commits Differential Revision: http://reviews.llvm.org/D18452 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@264876 91177308-0d34-0410-b5e6-96231b3b80d8
