ISALIST(7) Standards, Environments, and Macros ISALIST(7)

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This feature is obsolete and may be removed in a future version of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 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 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 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.


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.
