On 2887 32-bit MIPS systems this support is at the cost of increasing the 2888 size and complexity of the compiled FPU emulator. Thus if you are 2889 running a MIPS32 system and know that none of your userland binaries 2890 will require 64-bit floating point, you may wish to reduce the size 2891 of your kernel & potentially improve FP emulation performance by 2892 saying N here. 2893 2894 Although binutils currently supports use of this flag the details 2895 concerning its effect upon the O32 ABI in userland are still being 2896 worked on.
