Instruction Definitions:

SPARC64 V Extensions

This appendix describes the SPARC64 V-specific implementation of the instructions in Appendix A of Commonality. If an instruction is not described in this appendix, then no SPARC64 V implementation-dependency applies.

■See TABLE A-1of Commonality for the location at which general information about the instruction can be found.

■Section numbers refer to the parallel section numbers in Appendix A of Commonality.

TABLE A-1lists four instructions that are unique to SPARC64 V.

Each instruction definition consists of these parts:

1.A table of the opcodes defined in the subsection with the values of the field(s) that uniquely identify the instruction(s).

2.An illustration of the applicable instruction format(s). In these illustrations a dash (—) indicates that the field is reserved for future versions of the architecture and shall be 0 in any instance of the instruction. If a conforming SPARC V9 implementation encounters nonzero values in these fields, its behavior is undefined.

3.A list of the suggested assembly language syntax, as described in Appendix G, Assembly Language Syntax.
