--- Comment #9 from Paul Thomas <pault at gcc dot gnu.org> --- (In reply to Filip Kastl from comment #8) > Hmm, reverting the commit in question on the current trunk to see if it > still causes a slowdown doesn't work. I would have been very surprised if that patch had caused a slowdown. It concerned the order in which arguments were prepared for use in functions. It had no effect on what is done with the arguments but does correct for the order in which they were treated when there are inter-dependencies. Sorry but I don't think that you have the right patch. If you can show otherwise, I'll come back to it right away. Regards Paul
