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 in-
       struction 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 name(s) 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
