[PATCH] D56810: [Mem2Reg] Enable promotion for bitcastable load/store values

[Sergey Dmitriev via Phabricator via llvm-commits]

sdmitriev added a comment.

I am changing PromoteMemToReg function which can be called from other places besides mem2reg pass, so this change is not limited to mem2reg pass only. Regarding SROA, it does not handle alloca instructions outside of function entry block. We need to create allocas outside of entry in some cases and the use of PromoteMemToReg() seems to be the only option for registerizing them.
