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.
35#
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.
