42# From Linux arch/mips/Makefile
43#
44# GCC uses -G 0 -mabicalls -fpic as default. We don't want PIC in the kernel
45# code since it only slows down the whole thing. At some point we might make
46# use of global pointer optimizations but their use of $28 conflicts with
47# the current pointer optimization.
48#
49# The DECStation requires an ECOFF kernel for remote booting, other MIPS
50# machines may also. Since BFD is incredibly buggy with respect to
51# crossformat linking we rely on the elf2ecoff tool for format conversion.
