       isainfo - describe instruction set architectures

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

       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.

       The following options are supported:

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

	     Prints the name of the instruction set(s) used by	the  operating
	     system  kernel components such as device drivers and STREAMS mod‐

	     Prints the name of the native instruction set  used  by  portable
	     applications  supported  by  the current version of the operating

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

	     Prints  instruction  extensions  to the native ABI which are sup‐
	     ported by the platform.

       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

       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
	 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

		   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.
