[PATCH] D101177: [AMDGPU] Skip invariant loads when avoiding WAR conflicts

[Piotr Sobczak via Phabricator via llvm-commits]

piotr updated this revision to Diff 344710.
piotr added a comment.

Added the assert. The assert seems in order here - no hits in the lit tests or Vulkan CTS. There would have been hits in 194 lit tests if the assert had been placed here without the isInvariant check, which somewhat proves usefulness of the patch.
