73# GCC uses -G 0 -mabicalls -fpic as default. We don't want PIC in the kernel
74# code since it only slows down the whole thing. At some point we might make
75# use of global pointer optimizations but their use of $28 conflicts with
76# the current pointer optimization.
77#
78# The DECStation requires an ECOFF kernel for remote booting, other MIPS
79# machines may also. Since BFD is incredibly buggy with respect to
80# crossformat linking we rely on the elf2ecoff tool for format conversion.

90# We explicitly add the endianness specifier if needed, this allows

95# Certain gcc versions upto gcc 4.1.1 (probably 4.2-subversion as of
96# 2006-10-10 don't properly change the predefined symbols if -EB / -EL
97# are used, so we kludge that here. A bug has been filed at
