[PATCH] D107513: [MemCpyOpt/MemorySSA] Do not run the pass for prohibitively large number of memory accesses.

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

If the problem here updating MemorySSA in general, or only the use-optimized form? At one of the MemorySSA meetings we discussed the possibility of constructing MSSA without use optimization and then requesting that to happen later. MemCpyOpt itself doesn't particularly benefit from optimized uses.
