https://bugs.freedesktop.org/show_bug.cgi?id=90887 --- Comment #3 from Ilia Mirkin --- Gah! The inbound edge ordering having to be the same as in phi nodes has bit me before as well. I wonder if it wouldn't be simpler to just fix that, i.e. make phi nodes attach a bb reference to each argument. In any case, I'll be able to take a closer look in a week or so. Great detective work btw. FTR, nva5 should be able to allow manual reclocking on kernel 3.19+ (if you add nouveau.pstate=1), which should help decrease some of the perf difference wrt blob. Also, bug 90347 is completely different... that findFirstUse stuff is pretty dodgy in the first place, and it happens post-RA.
