NAME

       isalist - display the native instruction sets executable on this platform

SYNOPSIS

       isalist

DESCRIPTION

       isalist  prints  the names of the native instruction sets executable on this platform on the standard output, as returned by the SI_ISALIST
       command of  sysinfo(2).

       The names are space-separated and are ordered in the sense of best performance. That is, earlier-named instruction sets  may  contain  more
       instructions  than  later-named  instruction  sets;  a  program that is compiled for an earlier-named instruction sets will most likely run
       faster on this machine than the same program compiled for a later-named instruction set.

       Programs compiled for instruction sets that do not appear in the list will most likely experience performance degradation or not run at all
       on this machine.

       The  instruction  set  names  known to the system are listed in  isalist(5).  These names may or may not match predefined names or compiler
       options in the C language compilation system,

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.
