On 2880 32-bit MIPS systems this support is at the cost of increasing the 2881 size and complexity of the compiled FPU emulator. Thus if you are 2882 running a MIPS32 system and know that none of your userland binaries 2883 will require 64-bit floating point, you may wish to reduce the size 2884 of your kernel & potentially improve FP emulation performance by 2885 saying N here. 2886 2887 Although binutils currently supports use of this flag the details 2888 concerning its effect upon the O32 ABI in userland are still being 2889 worked on.
