31# From Linux arch/mips/Makefile

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

48# to RAM. $28 is always used as gp.
