--- Comment #3 from Peter Bergner <bergner at gcc dot gnu.org> --- It's interesting that VSX reg costs is 4000, but the FPR and Altivec regs are cost zero like GPRs. I wonder why that is. These look like d-form memory accesses and we don't have d-form Altivec memory ops, so I'd expect those to have non-zero cost. Sure, FPRs have d-form ops, but why do we attempt to assign FPRs before GPRs again???
