NAME

       getisax - extract valid instruction set extensions

SYNOPSIS

       #include <sys/auxv.h>

       uint_t getisax(uint32_t *array, uint_t n);

DESCRIPTION

       The  getisax()  function sets the vector array of n 32-bit integers to contain the bits from the AV_xxx_yyy namespace of the given instruc-
       tion set architecture.

       Values for AV_xxx_yyy are as follows:

   SPARC
       AV_SPARC_MUL32	       32x32-bit smul/umul is efficient

       AV_SPARC_DIV32	       32x32-bit sdiv/udiv is efficient

       AV_SPARC_FSMULD	       fsmuld instruction is efficient

       AV_SPARC_V8PLUS	       V9 instructions available to 32-bit apps

       AV_SPARC_POPC	       popc instruction is efficient

       AV_SPARC_VIS	       VIS instruction set is supported

       AV_SPARC_VIS2	       IS2 instruction set is supported

   x86
       AV_386_FPU	       x87-style floating point

       AV_386_TSC	       rdtsc instruction

       AV_386_CX8	       cmpxchg8b instruction

       AV_386_SEP	       sysenter and sysexit

       AV_386_AMD_SYSC	       AMD's syscall and sysret

       AV_386_CMOV	       conditional move instructions

       AV_386_MMX	       MMX instructions

       AV_386_AMD_MMX	       AMD's MMX instructions

       AV_386_AMD_3DNow        AMD's 3Dnow! instructions

       AV_386_AMD_3DNowx       AMD's 3Dnow! extended instructions

       AV_386_FXSR	       fxsave and fxrstor

       AV_386_SSE	       SSE instructions and regs

       AV_386_SSE2	       SSE2 instructions and regs

       AV_386_PAUSE	       use pause instruction (in spin loops)

       AV_386_SSE3	       SSE3 instructions and regs

       AV_386_MON	       monitor/mwait instructions

RETURN VALUES

       The getisax() function returns the number of array elements that contain non-zero values.

EXAMPLES

       Example 1: Use getisax() to determine if the SSE2 instruction set is present.

       In the following example, if the message is written, the SSE2 instruction set is present and fully supportred by the operating system.

       uint_t ui;

       (void) getisax(&ui, 1);

       if (ui & AV_386_SSE2)
	       printf("SSE2 instruction set extension is present.
");
