There are two FP emulators in IRIX. The first one is fairly old, was already
used in RISC/os and is written in assembler. I'm not sure if it can
properly deal with MIPS IV. It's successor is written in C and is what's
currently being used in IRIX, is pretty clean and maintainable code. It
was clearly written with a heavily optimizing compiler such as SGI's in
mind and I assume that it won't perform well without major restructuring
when compiled with GCC. On the other side it's as far as I know the only
package that gets all the cornercases right.
