47 # GCC uses -G 0 -mabicalls -fpic as default. We don't want PIC in the kernel
48 # code since it only slows down the whole thing. At some point we might make
49 # use of global pointer optimizations but their use of $28 conflicts with
50 # the current pointer optimization.
52 # The DECStation requires an ECOFF kernel for remote booting, other MIPS
53 # machines may also. Since BFD is incredibly buggy with respect to
54 # crossformat linking we rely on the elf2ecoff tool for format conversion.
