------- Comment #2 from rguenth at gcc dot gnu dot org 2010-04-09 08:46 -------
Well. I guess we should simply not run IPA passes at -O0 (like we do not
support enabling random scalar passes at -O0, though in the end I'd like
to support that for poor-mans unit-testing).
I suppose the IPA fixup pass needs to be run by the pass manager dependent
on a property which IPA passes can re-set.
