2839 | EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On | |
2840 | 32-bit MIPS systems this support is at the cost of increasing the | |
2841 | size and complexity of the compiled FPU emulator. Thus if you are | |
2842 | running a MIPS32 system and know that none of your userland binaries | |
2843 | will require 64-bit floating point, you may wish to reduce the size | |
