[PATCH] D107271: [BasicTTIImpl][LoopUnroll] getUnrollingPreferences(): emit ORE remark when advising against unrolling due to a call in a loop

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Probably loop-unroll should have a generic message along the lines of "runtime loop unrolling disabled for this loop due to target heuristic", if we don't already.

If that isn't clear enough, then I guess this is the only way to emit the diagnostic we want without significantly refactoring the code.
