--- Comment #12 from wmi at google dot com --- Yes, I agree it is a problem that memrefs_conflict_p doesn't take effect. But I am still wondering even if memrefs_conflict_p doesn't take effect, the alias oracle query in rtx_refs_may_alias_p should have returned may-alias for the load and store. Why rtx_refs_may_alias_p failed to do that?
