--- Comment #1 from Florian Hahn <Florian.Hahn at arm.com> ---
Should be fixed in https://reviews.llvm.org/rL347524.

The problem was that the code was using OriginalOp to access the source of the
ssa_copy, but OriginalOp refers to the original value in the IR before
renaming, not the actual source operand.
