[PATCH] D59295: [AMDGPU] Pre-allocate WWM registers to reduce VGPR pressure.

[Neil Henning via Phabricator via llvm-commits]

sheredom updated this revision to Diff 191099.
sheredom added a comment.

Reduce the number of DPP calls in the test for cleanliness, and reintroduce the convergent on WWM. The CFG test contains the bug that was exposed by the lack of convergent on WWM, LLVM will **sink** the WWM statement out of the branch which totally messes up all calculations.
