Mangling the BFD target isn't going to help you here either, although of course if there's another BFD that we should be using while preserving -mno-fdpic semantics for the kernel build then we can trivially drop that in, too. It's certainly worth trying to wean the compressed image off of libgcc, but we're not quite at that point yet. _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
