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. Michael Slater, Microprocessor Report mslater@cup.portal.com
