# code since it only slows down the whole thing.  At some point we might make
# use of global pointer optimizations but their use of $28 conflicts with
# the current pointer optimization.

# machines may also.  Since BFD is incredibly buggy with respect to
# crossformat linking we rely on the elf2ecoff tool for format conversion.
