On 2879 32-bit MIPS systems this support is at the cost of increasing the 2880 size and complexity of the compiled FPU emulator. Thus if you are 2881 running a MIPS32 system and know that none of your userland binaries 2882 will require 64-bit floating point, you may wish to reduce the size 2883 of your kernel & potentially improve FP emulation performance by 2884 saying N here. 2885 2886 Although binutils currently supports use of this flag the details 2887 concerning its effect upon the O32 ABI in userland are still being 2888 worked on.
