1541 Loongson 2F03 and later have fixed these issues and no workarounds
1542 are needed. The workarounds have no significant side effect on them
1543 but may decrease the performance of the system so this option should

2474 When this is enabled, the kernel will support use of 64-bit floating
2475 point registers with binaries using the O32 ABI along with the
2476 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2477 32-bit MIPS systems this support is at the cost of increasing the
2478 size and complexity of the compiled FPU emulator. Thus if you are
2479 running a MIPS32 system and know that none of your userland binaries
2480 will require 64-bit floating point, you may wish to reduce the size
2481 of your kernel & potentially improve FP emulation performance by

2484 Although binutils currently supports use of this flag the details
2485 concerning its effect upon the O32 ABI in userland are still being

2488 be considered experimental and only enabled by those working upon
