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  sys‐
       tem.  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 isal‐
       ist(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  operat‐
		ing  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 sup‐
		ported by the platform.

EXAMPLES
       Example 1: Invoking isainfo on a 32-bit x86 Platform

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

       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 command is
		       unable to recognize attributes of the system  on	 which
		       it is running. An error message is printed to stderr.

ATTRIBUTES
       See attributes(5) for descriptions of the following attributes:
