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.
