3016597ce172SPaul Burton	  32-bit MIPS systems this support is at the cost of increasing the
3017597ce172SPaul Burton	  size and complexity of the compiled FPU emulator. Thus if you are
3018597ce172SPaul Burton	  running a MIPS32 system and know that none of your userland binaries
3019597ce172SPaul Burton	  will require 64-bit floating point, you may wish to reduce the size
