--- Comment #15 from Segher Boessenkool <segher at gcc dot gnu.org> --- (In reply to Aldy Hernandez from comment #12) > (It really irks me that the PPC backend has backend behavior that depends on > what assembler (or cross assembler) is available at configure time. It > makes it difficult to reproduce bugs with crosses.) This is so that it is possible to build GCC with a (slightly) older binutils. You should never have problems with this if you always use a binutils for your cross toolchains that is approximately as old as your GCC. Did you use an ancient cross assembler?
