NAME

optisa - determine which variant instruction set is optimal to use

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(7).

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.

SEE ALSO

isalist(1), uname(1), attributes(7), isalist(7)

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.
