I'd certainly like to see the -mcall-* code that pretends to support linking for one target using another target's compiler removed. That way non-FreeBSD targets wouldn't need freebsd-spec.h, rs6000/sysv4.h wouldn't need loads of specs that are really irrelevant to all but one target, and you could probably make powerpc*-linux* use the toplevel gnu-user.h and linux.h like almost all other Linux kernel targets. That these powerpc* targets are doing things differently from all other architectures is a nuisance when making changes across all targets (and I don't think what they are doing is a useful intermediate step towards a multi-target compiler). -- Joseph S.
