Not okay. > If powerpc maintainer doesn't like this way, another alternative is add a > target hook in RA to still use GENEREAL_REGS for other targets, but use > NO_REGS only for x86. Also not okay. Please solve the fundamental problem in cost estimation you created, don't let all targets try to fix it in different ways :-(
