--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Strictly speaking your asm should be incorrect as GCC does not consider
it to use/clobber "local" global memory.
That manifests itself in IPA reference computing that bar is not accessing
'a' and thus we can optimize the load across the call.
So, kind-of confirmed.
