Florian Hahn	96e83d3705	[LV] Use IRBuilder to create and optimize middle-block compare. Split off from D150398 to avoid builder-related diff changes there. Using IRBuilder to create ICmps simplifies the result if both operands are constants. Reviewed By: Ayal Differential Revision: https://reviews.llvm.org/D158332	2023-08-29 11:42:18 +01:00
Florian Hahn	1746ac42ca	[LV] Forget SCEVs for exit phis after vectorization. After vectorization, the exit blocks of the original loop will have additional predecessors.

After vectorization, the exit blocks of the original loop will have additional
predecessors. Invalidate SCEVs for the exit phis in case SE looked through
single-entry phis.
