Lucas is insanely dependent on register allocation and scheduling. With
-fweb and -frename-registers both disabled at -O2
This reminds me. I committed a number of regrename speedup patches
earlier this year - does anyone think it would be a good idea to add
that to -O2 now?
Definitely on i686, since it disables pre-regalloc scheduling. You
cannot get decent scheduling there without regrename.
