Law <law at gcc dot gnu.org> --- Yea, we definitely want pressure sensitive scheduling. While it's more valuable for scalar cases, it can help with some vector as well. Also note there's two variants of the pressure sensitive scheduler support. I think we use the newer one which is supposed to be better, but I don't think we've really evaluated one over the other. Setting issue rate to 1 for the first pass scheduler is a bit of a hack, though not terribly uncommon. It's something I've wanted to go back and review, so fully support you digging into that as well.
