[PATCH] D105207: [debuginfo][lsr] SCEV-based salvaging for LoopStrengthReduction

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Correct me if i'm misremembering things, but weren't there something like that (SCEV-driven debuginfo salvaging/recovery) already,
and it had problems with holding to the dead IR, and was removed because of that?
Does have similar correctness concerns?
