I investigated the problem with complex-6.c and the point of divergence
is in .136r.lreg where we choose different register preferences
from before your change.

Can you check if reverting Dale's patch fixes the failures? I'm more and more inclined to do so since (as expected) the reload changes had no effect on everything but i386, while the regclass changes are triggering bugs or other crashes on powerpc, sh64, and now x86_64. Which is not appropriate for stage3, I think.
