Integer Multiply/Divide on Sparc

[Robert D. Silverman]

Does any have, of know of software for the SPARC [SUN-4] that will
perform the following:

(1) Multiply two unsigned 32-bit integers, yielding a 64 bit product
    stored in two registers?

(2) Take a 64 bit product and divide it by a 32 bit (unsigned) integer
    yielding a 32-bit quotient and remainder?
 
or (3) Compute A*B Mod C directly?


The SPARC is brain dead [as were its designers] when it comes to doing
integer arithmetic. It can't multiply and it can't divide.

Trying to convert to floating point, do the arithmetic, then convert
back is far too slow. (I've already tried).
