Lauderdale Lines: 12 Note that HP-PA has no integer multiply instruction. Multiplying by a constant gives fairly good performance since the comiler produces as series of shifts and adds. Multiplying by variables uses the millicode. For integer division there are instructions that are used which are primitive instructions which allow the process to be performed in single cycle steps.
