[PATCH] D16602: StructurizeCFG: Add an option for skipping regions with only uniform branches

[Matt Arsenault via llvm-commits]

arsenm added a comment.

Do we need to worry about updating the DivergenceAnalysis as the control flow is changed in the non-uniform regions? Sometimes it introduces new xor instructions which won't be in DA's value map.
