NAME

       isalist - the native instruction sets known to Solaris software

       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.

   SPARC Platforms
       Where  appropriate,  correspondence  with a given value of the -xarch option of Sun's C 4.0 compiler is indicated. Other compilers may 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) may 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 produced 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 pro-
	   duced 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 instructions.

       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.

    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.
