Tom Stellard	1d5e6d4bdc	AMDGPU/SI: Improve MachineSchedModel definition This patch contains a few improvements to the model, including: - Using a single resource with a defined buffers size for each memory unit. - Setting the IssueWidth correctly. - Fixing latency values for memory instructions. shader-db stats: 16429 shaders in 3231 tests Totals: SGPRS: 318232 -> 312328 (-1.86 %) VGPRS: 208996 -> 209346 (0.17 %) Code Size: 7147044 -> 7166440 (0.27 %) bytes LDS: 83 -> 83 (0.00 %) blocks Scratch: 1862656 -> 1459200 (-21.66 %) bytes per wave Max Waves: 49182 -> 49243 (0.12 %) Wait states: 0 -> 0 (0.00 %)A Differential Revision: http://reviews.llvm.org/D18453 llvm-svn: 264877	2016-03-30 16:35:13 +00:00
Tom Stellard	0bc954e3bc	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 llvm-svn: 264876	2016-03-30 16:35:09 +00:00
