Since the multiply and divide instructions for all the other extant
32bit microprocessors has be discussed, I might as well add the
AT&T WE(TM) 32100.

The WE32100 supports 8x8=8, 16x16=16 and 32x32=32 bit multiplication
division and modulo.  No 64 bit result or dividend provided.  This
is consistent with the data types provided by the chip, but a pain if
you really want the upper 32 bits.  The chip does indicate an overflow
by flag and maskable trap.
