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