I don't see out-of-tree targets as providing a relevant case for blocking cleanups, and in any case I think GCC should require a reasonably recent binutils (more recent than 2.17) on all targets except where it is specifically supporting a "native" system assembler or linker (even there, I don't think system assembler support is particularly important except where the system tools have features missing from GNU binutils). The legacy options still exist - it's just that they'll be passed to the assembler in the canonical -mcpu= form, so you need an assembler supporting that form (which any GNU assembler from the past five years will do - and I don't think supporting a five-year disparity between GCC and binutils versions is productive). -- Joseph S.
