--- Comment #4 from Uroš Bizjak <ubizjak at gmail dot com> --- (In reply to Uroš Bizjak from comment #3) > I have patch in testing. The call_insn RTX should always define its mode. Previously, the state was switched to DIRTY by an eventual move to a 256bit function argument register (even when the move was useless) in front of the call_insn. Nowadays, this is not true anymore, so call_insn should switch the state to DIRTY mode on its own.
