SYNOPSIS

optisa instruction_set...
DESCRIPTION

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

EXIT STATUS

The following exit values are returned: 0

One of the instruction_set values you specified is printed by this command.

1

There is no output; that is, this machine cannot use any instruction_set that you specified with the optisa command.

NOTES

optisa is preferable to uname -p or uname -m (see uname(1)) in determining which of several binary versions of a given program should be used on the given machine.
