isalist(5)
NAME
DESCRIPTION
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
190
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
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 Hal
SPARC64 floating multiply-add and multiply-subtract
instructions.
