NAME
     isainfo - describe instruction set architectures

SYNOPSIS
     isainfo [ [-v] [-b | -n | -k] | [-x]]


DESCRIPTION
     The isainfo utility is used to identify  various  attributes
     of  the  instruction  set  architectures  supported  on  the
     currently running system. Among the questions it can  answer
     are  whether  64-bit  applications are supported, or whether
     the running kernel uses 32-bit or 64-bit device drivers.


     When invoked with no options, isainfo prints  the  names  of
     the  native  instruction  sets for applications supported by
     the current version of the operating  system.  These  are  a
     subset  of  the  list  returned  by  isalist(1).  The subset
     corresponds to the basic applications environments supported
     by the currently running system.

OPTIONS
     The following options are supported:

     -b    Prints the number of bits in the address space of  the
           native instruction set.


     -k    Prints the name of the instruction set(s) used by  the
           operating  system  kernel  components  such  as device
           drivers and STREAMS modules.


     -n    Prints the name of the native instruction set used  by
           portable applications supported by the current version
           of the operating system.


     -v    When used with the -b, -k or -n options,  prints  more
           detailed information.


     -x    Prints instruction extensions to the native ABI  which
           are supported by the platform.

User Commands                                          isainfo(1)



     The following example invokes isainfo on a 32-bit x86  plat-
     form:


       example% isainfo -v
       32-bit i386 applications

       example% isainfo -k
       i386



     Example 2 Invoking isainfo on a System  Running  the  64-bit
     Operating System on a 64-bit SPARC Processor


     The following example invokes isainfo on  a  system  running
     the 64-bit operating system on a 64-bit SPARC processor:


       example% isainfo
       sparcv9 sparc
       example% isainfo -n
       sparcv9
       example% isainfo -v
       64-bit sparcv9 applications
       32-bit sparc applications
       example% isainfo -vk
       64-bit sparcv9 kernel modules



     Example 3 Invoking isainfo -x on an AMD Opteron CPU


     The following example invokes isainfo with the -x option  on
     an AMD Opteron CPU:


       example% isainfo -x
       i386: fpu tsc cx8 sep cmov mmx ammx a3dnow a3dnowx fxsr sse sse2 pause



EXIT STATUS
     Non-zero    Options are not specified correctly, or the com-
                 mand  is  unable  to recognize attributes of the
                 system on which it is running. An error  message
                 is printed to stderr.
