1569 | Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which | |
1570 | require workarounds. Without workarounds the system may hang | |
1571 | unexpectedly. For more information please refer to the gas | |
1572 | -mfix-loongson2f-nop and -mfix-loongson2f-jump options. | |
1573 | ||
1574 | Loongson 2F03 and later have fixed these issues and no workarounds | |
1575 | are needed. The workarounds have no significant side effect on them | |
1576 | but may decrease the performance of the system so this option should | |
1577 | be disabled unless the kernel is intended to be run on 2F01 or 2F02 | |

2492 | EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On | |
2493 | 32-bit MIPS systems this support is at the cost of increasing the | |
2494 | size and complexity of the compiled FPU emulator. Thus if you are | |
2495 | running a MIPS32 system and know that none of your userland binaries | |
2496 | will require 64-bit floating point, you may wish to reduce the size | |
