[PATCH] D85530: [AMDGPU] Don't cluster stores

[Carl Ritson via Phabricator via llvm-commits]

critson added a comment.

I tried this change with game traces on GFX10.

I could not convince myself that there was any statically significant changes in performance.
Some small gains, some small losses, nothing outside the range of variance.

I do however wonder if this would be better as a tuning option?
The same could also be said for load clustering as essentially you are trading VGPR pressure for VMEM access efficiency (e.g. stalls).
