I strongly doubt that they will be different from the options
supported both in cc and fbe in the Solaris Studio 12.3 release:
-xarch=sparc Enables the assembler to accept instructions
defined in the SPARC-V9 architecture. The
resulting object code is in ELF32 format when
compiled with -m32, ELF64 format with -m64. It
will not execute on a Oracle Solaris V8 system
(a machine with a V8 processor). It will exe-
cute on a Oracle Solaris V8+ system.
-xarch=sparcvis
Enables the assembler to accept instructions
defined in the SPARC-V9 architecture plus the
instructions in the Visual Instruction Set
(VIS) version 1.0. The resulting object code
is in V8+ ELF32 format when compiled with -m32,
ELF64 format with -m64. It will not execute on
a Oracle Solaris system with a V8 processor. It
will execute on a Oracle Solaris system with a
V8+ processor.
-xarch=sparcvis2
Enables the assembler to accept instructions
defined in the SPARC-V9 architecture, plus the
instructions in the Visual Instruction Set
(VIS) version 2.0, with UltraSPARC-III exten-
sions. The resulting object code is in V8+
ELF32 format when compiled with -m32, ELF64
format with -m64.
-xarch=sparcvis3
Accept instructions defined for the SPARC VIS
version 3 of the SPARC-V9 ISA which are
instructions from the SPARC-V9 instruction set,
plus the UltraSPARC extensions, including the
Visual Instruction Set (VIS) version 1.0, the
UltraSPARC-III extensions, including the Visual
Instruction Set (VIS) version 2.0, the fused
multiply-add instructions, and the Visual
Instruction Set (VIS) version 3.0
-xarch=sparcfmaf
Accept instructions defined for the sparcfmaf
version of the SPARC-V9 ISA, plus the
UltraSPARC extensions, including the Visual
Instruction Set (VIS) version 1.0, the
UltraSPARC-III extensions, including the Visual
Instruction Set (VIS) version 2.0, and the
SPARC64 VI extensions for floating-point
multiply-add.
-xarch=sparcima
Accept instructions defined for the sparcima
version of the SPARC-V9 ISA which are instruc-
tions from the SPARC-V9 instruction set, plus
the UltraSPARC extensions, including the Visual
Instruction Set (VIS) version 1.0, the
UltraSPARC-III extensions, including the Visual
Instruction Set (VIS) version 2.0, the SPARC64
VI extensions for floating-point multiply-add,
and the SPARC64 VII extensions for integer
multiply-add.
-xarch=sparc4
Accept instructions defined for the sparc4 ver-
sion of the SPARC-V9 ISA which are instructions
from the SPARC-V9 instruction set, plus the
extensions, which includes VIS 1.0, the
UltraSPARC-III extensions, which includes VIS
2.0, the fused floating-point multiply-add
instructions, VIS 3.0, and SPARC4 instructions.
