  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.

  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.
