       isainfo - describe instruction set architectures

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

       The  isainfo  utility is used to identify various attributes of the instruction set archi-
       tectures 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 envi-
       ronments supported by the currently running system.

       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 compo-
	     nents such as device drivers and STREAMS modules.

       -n    Prints the name of the native instruction set used  by  portable  applications  sup-
	     ported 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.

       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

       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.

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

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWcsu			   |

       isalist(1), uname(1), psrinfo(1M), getisax(2), sysinfo(2), attributes(5), isalist(5)
