[PATCH] D85046: [SCEV] If Start >= RHS, simplify (Start smin RHS) to RHS for trip counts (PR46924, PR46939)

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

For the record, this was a 1% compile-time regression on SPASS (https://llvm-compile-time-tracker.com/compare.php?from=7ba82a7320df82d07d3d5679bce89b14526b536c&to=ee1c12708a4519361729205168dedb2b61bc2638&stat=instructions). This seems to be caused due to a 2.3% increase in code size (https://llvm-compile-time-tracker.com/compare.php?from=7ba82a7320df82d07d3d5679bce89b14526b536c&to=ee1c12708a4519361729205168dedb2b61bc2638&stat=size-text), with some of the files getting 20-30% larger. Not particularly unexpected for this kind of change though.
