NAME

       isalist - the native instruction sets known to Solaris software

DESCRIPTION

       The possible instruction set names returned by isalist(1) and the SI_ISALIST command of sysinfo(2) are listed here.

       The  list is ordered within an instruction set family in the sense that later names are generally faster then earlier names; note that this
       is in the reverse order than listed by isalist(1) and sysinfo(2). In the following list of values,  numbered  entries  generally  represent
       increasing performance; lettered entries are either mutually exclusive or cannot be ordered.

       This  feature  is  obsolete  and may be removed in a future version of Solaris. The lists below do not reflect all the extensions that have
       been made by modern processors. See getisax(2) for a better way to handle instruction set extensions.

   SPARC Platforms
       Where appropriate, correspondence with a given value of the -xarch option of Sun's C 4.0 compiler is indicated. Other compilers might  have
       similar options.

       1a. sparc		  Indicates  the SPARC V8 instruction set, as defined in  The SPARC Architecture Manual, Version 8, Prentice-Hall,
				  Inc., 1992. Some instructions (such as integer multiply and divide, FSMULD, and all floating point operations on
				  quad operands) can be emulated by the kernel on certain systems.

       1b. sparcv7		  Same as sparc. This corresponds to code produced with the -xarch=v7 option of Sun's C 4.0 compiler.

       2. sparcv8-fsmuld	  Like	sparc, except that integer multiply and divide must be executed in hardware. This corresponds to code pro-
				  duced with the -xarch=v8a option of Sun's C 4.0 compiler.

       3. sparcv8		  Like sparcv8-fsmuld, except that FSMULD must also be executed in hardware. This  corresponds	to  code  produced
				  with the -xarch=v8 option of Sun's C 4.0 compiler.

       4. sparcv8plus		  Indicates  the  SPARC  V8 instruction set plus those instructions in the SPARC V9 instruction set, as defined in
				  The SPARC Architecture Manual, Version 9, Prentice-Hall, 1994, that can be used according to	The V8+  Technical
				  Specification. This corresponds to code produced with the -xarch=v8plus option of Sun's C 4.0 compiler.

       5a. sparcv8plus+vis	  Like	sparcv8plus, with the addition of those UltraSPARC I Visualization Instructions that can be used according
				  to  The V8+ Technical Specification. This corresponds to code produced with the -xarch=v8plusa option of Sun's C
				  4.0 compiler.

       5b. sparcv8plus+fmuladd	  Like	sparcv8plus, with the addition of the Fujitsu SPARC64 floating multiply-add and multiply-subtract instruc-
				  tions.

       6. sparcv9		  Indicates the SPARC V9 instruction set, as defined in  The SPARC Architecture Manual, Version 9,  Prentice-Hall,
				  1994.

       7a. sparcv9+vis		  Like sparcv9, with the addition of the UltraSPARC I Visualization Instructions.

       7b. sparcv9+vis2 	  Like sparcv9, with the addition of the UltraSPARC III Visualization Instructions.

       7c. sparcv9+fmuladd	  Like sparcv9, with the addition of the Fujitsu SPARC64 floating multiply-add and multiply-subtract instructions.

   x86 Platforms
       1. i386		     The Intel 80386 instruction set, as described in  The i386 Microprocessor Programmer's Reference Manual.

       2. i486		     The  Intel  80486	instruction  set, as described in  The i486 Microprocessor Programmer's Reference Manual. (This is
			     effectively i386, plus the CMPXCHG, BSWAP, and XADD instructions.)

       3. pentium	     The Intel Pentium instruction set, as described in  The Pentium Processor User's Manual. (This is	effectively  i486,
			     plus the CPU_ID instruction, and any features that the CPU_ID instruction indicates are present.)

       4. pentium+mmx	     Like pentium, with the MMX instructions guaranteed present.

       5. pentium_pro	     The Intel PentiumPro instruction set, as described in  The PentiumPro Family Developer's Manual. (This is effectively
			     pentium, with the CMOVcc, FCMOVcc, FCOMI, and RDPMC instructions guaranteed present.)

       6. pentium_pro+mmx    Like pentium_pro, with the MMX instructions guaranteed present.

       7. amd64 	     The AMD Opteron instruction set, as described in the AMD64 Architecture Programmer's Manual.
