[PATCH] D79783: [LV] Fallback strategies if tail-folding fails

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer updated this revision to Diff 278125.
SjoerdMeijer added a comment.

Changed option `-prefer-predicate-over-epilog` to accept a more descriptive value rather than a cryptic numeric value.

Also a friendly ping. :-)
