[PATCH] D89207: [MemCpyOpt] Port to MemorySSA

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Some preliminary compile-time numbers: https://llvm-compile-time-tracker.com/index.php?branch=nikic/perf/memcpy-mssa The last commits are, from the bottom to top: Enabling MSSA DSE, enabling MSSA MemCpyOpt and moving one MemCpyOpt pass next to a DSE pass, to avoid an additional computation of MSSA. The last two commits together actually end up being a mild compile-time improvement. So at least this looks viable.
