 * Part Number: 805-1394-03
 * May 2001
 *
 * Version of available VIS instructions can be detected through
 * the `machdep.vis` sysctl. A value of "0" means that such
 * instructions are unavailable. All SPARCv9 hardware should support
 * at least VIS 1, while VIS 2 requires UltraSPARC-III or newer.
 *
 * GCC needs -mvis for VIS, and -mvis2 for VIS 2. However, its
 * builtins are incomplete and some cause problematic typing issues
 * with Sun's API, so they're mostly avoided.
