Application software for the 32-bit SPARC-V8 (Version8) architecture can execute, unchanged, on SPARC-V9 systems. << This appendix describes changes made to the SPARC instruction set due to the SPARC-V9 architecture. Updated:  19 May 2020/ %���� Items in Open Research are protected by copyright, with all rights reserved, unless otherwise indicated. Any instruction not directly matched ought to generate an illegal instruction trap when executed or emulated. For example, all the BPr opcodes are matched with a single BPr constructor with the condition type as an extra field. Some instructions matched may later generate an illegal instruction trap.

Appendix E, “SPARC-V9 Instruction Set,”describes the SPARC-V9 instruction set and the changes due to the SPARC-V9 implementation. Any instruction that could cause some other trap and could be detected here (possibly in equations, e.g., the quad-precision floating-point encoding of registers) will have an constructor that accepts these invalid instructions and a constructor that accepts only the truly “valid” instructions.
