--- Comment #30 from Jan Hubicka <hubicka at ucw dot cz> --- > > I uploaded a patch to check all aliases for parameter alignments. It > fixes eon on x32. Thanks for looking into this. The bug is however a bit earlier. The propagation stage should never put anything into lattices of aliases (we probably should add checking assert that those are never used) and instead of that always go across the alias into the final symbol. I guess somewhere there is missing call to ultimate_alias_target (or function_symbol) Honza
