--- Comment #1 from David Blaikie <dblai...@gmail.com> ---
This behavior is intentional.
-O0 IR carries with it that contract that it should not be optimized - so opt
satisfies that request by running the optimization passes, but they all do
nothing to modify -O0 IR.
This is important when preserving the semantic request of -O0 in IR that is
merged from multiple other IR files, some of which may be compiled with -O0 and
some with optimizations enabled.
