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 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 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 operating system kernel components such as dev-
ice 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 supported by the platform.

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.
