In that case, the fix looks bloody obvious.  Best performance is with post-regalloc scheduling pass on and pre-regalloc scheduling pass off, so we 
should make that the default configuration.  I don't see any downside.  Why doesn't one of you propose that to the GCC mailing list and see if 
someone knows of a downside I don't?  (I should really get back to my configury work...)
