[PATCH] D108087: [SimpleLoopUnswitch] Create SimpleLoopNestUnswitch pass

[toshiki maekawa via Phabricator via llvm-commits]

uint256_t updated this revision to Diff 368543.
uint256_t added a comment.

- No longer do `findBestUnswitchTI` every time we call `unswitchBestCondition`.
- Remove the condition `BestUnswitchTIForLoopNest == findBestUnswitchTI`, which was confusing.
