All functions are now implemented, now it's time for validation testing. I've already checked out the divide and modulus functions, since I knew that they would tricky.

I've started testing 32-bit multiplies, and I keep seeing results consistent with unsigned multiply, regardless of the type of operation called for. I'm also seeing that the __mulsi3 function in libgcc is not being used. It's been long enough that I've forgotten if I've implemented a 32-bit multiply recipe in the machine description file. I better check that out.
