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

43 # On the other hand, we want PIC in the U-Boot code to relocate it from ROM
44 # to RAM. $28 is always used as gp.
