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 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.
The following options are supported:
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
