--- Comment #11 from Segher Boessenkool <segher at gcc dot gnu.org> --- Such a rewrite function would be great I think. I don't want the -mdejagnu-cpu thing to need any deeper code changes, but this attacks the one problem the simple -mcpu override did not: specs. (I cannot find where these rewrite functions are defined for arm/aarch64, huh.)
