Yes, you set call_really_used_regs for the ALTIVEC where you set
call_used_regs. If you need to keep those two in sync for ALTIVEC, why
don't you need to keep call_really_used_regs in sync for ALL of the other
conditional setting of call_used_regs?
If it is deemed acceptable, I think Stan's method is better. We
also force other dependencies in the prologue and epilogue.
