 * Flags used in AT_SUN_HWCAP elements to describe various userland
 * instruction set extensions available on different processors.
 * The basic assumption is that of the i386 ABI; that is, i386 plus i387
 * floating point.
 *
 * Note that if a given bit is set; the implication is that the kernel
 * provides all the underlying architectural support for the correct
 * functioning of the extended instruction(s).
