-# The RS/6000 has no unsigned 32x32->64 bit multiplication instruction. To
-# obtain that operation, we have to use the 32x32->64 signed multiplication
-# instruction, and add the appropriate compensation to the high limb of the
-# result. We add the multiplicand if the multiplier has its most significant
-# bit set, and we add the multiplier if the multiplicand has its most
-# significant bit set. We need to preserve the carry flag between each
-# iteration, so we have to compute the compensation carefully (the natural,
-# srai+and doesn't work). Since the POWER architecture has a branch unit
-# we can branch in zero cycles, so that's how we perform the additions.
