[PATCH] D109280: [WIP][DSE] Memory intrinsics like memset, memcpy, memmove are removed if they are overwritten by a store in a loop

[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added a comment.

All your 3 examples - should just loopidiomrecognize just catch it and produce intrinsics? (Not sure about ordering of DSE and LoopIdiom)

Any other motivating cases/benchmarks?

Currently I see no reason to increase complexivity of DSE as LoopIdiom + DSE should work fine together to handle them.
