optisa - determine which variant instruction set is optimal
optisa prints which instruction_set out of the ones speci-
fied 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).
See attributes(5) for descriptions of the following attri-
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
| Availability | SUNWcsu |
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
isalist(1), uname(1), attributes(5), isalist(5)
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.
