------- Comment #1 from pinskia at gcc dot gnu dot org  2008-10-27 22:47 -------
I was looking into regclass lately and noticed both that and ira-costs.c does
not take '!' into account at all.  While reload does.

------- Comment #2 from pinskia at gcc dot gnu dot org  2008-10-27 23:34 -------
Fixing regclass/ira-costs does not fix this bug as there is only one
alternative but it might help other targets and other parts of the rs6000
back-end.
