isainfo

isainfo(1)                                                         User Commands                                                        isainfo(1)

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 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 isalist(1). The subset corresponds to the basic  applications  environ-
       ments 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 mod-
                ules.

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

       -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.

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.
