[PATCH] D137574: PEI should be able to use backward walk in replaceFrameIndicesBackward.

[Alexander via Phabricator via llvm-commits]

alex-t added a comment.

TargetRegisterInfo::eliminateFrameIndex invalidate iterator passed to it. It can remove the instruction or change the number of its operands.
I am thinking of changing its interface to make it return an iterator that points to the new/changed instruction to let caller handle this.
