With regard to SPARC's lack of integer multiply/divide:

I suspect this is primarily a consequence not of the designer's attitude
toward arithmetic, but was a result of the goal to implement the first
CPU chip in a 20,000-gate ASIC.  They had to be economical with the
transistors.

I expect that future SPARC implementations will add integer multiply and
divide instructions.  Unfortunately, existing software won't use these
instructions.
