| # 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. |

| # The DECStation requires an ECOFF kernel for remote booting, other MIPS |
| # machines may also. Since BFD is incredibly buggy with respect to |
| # crossformat linking we rely on the elf2ecoff tool for format conversion. |
