[PATCH] D123394: [CodeGen] Late cleanup of redundant address/immediate definitions.

[Jonas Paulsson via Phabricator via llvm-commits]

Why is MachineCopyPropagation only local? Has anyone tried a global version? I am curious because the type of cleanup this patch is doing seems to benefit greatly from global reuse of values. It would be interesting to know if there just wasn't much benefit, or if it just seems too complex, or what else the reasoning might be...
