DESCRIPTION

13       optisa  prints  which  instruction_set out of the ones specified in the
14       command will perform best on  this machine.  In this case, ``best''  is
15       defined  by  the  order  in which instruction set names are returned by
16       isalist(1). Possible values for instruction_set  are  given  in   isal‐
17       ist(5).
