| 42 | # GCC uses -G 0 -mabicalls -fpic as default. We don't want PIC in the kernel |
| 43 | # code since it only slows down the whole thing. At some point we might make |
| 44 | # use of global pointer optimizations but their use of $28 conflicts with |
| 45 | # the current pointer optimization. |
| 46 | # |
| 47 | # The DECStation requires an ECOFF kernel for remote booting, other MIPS |
| 48 | # machines may also. Since BFD is incredibly buggy with respect to |
| 49 | # crossformat linking we rely on the elf2ecoff tool for format conversion. |
