| 1 # MIPS32 Instruction Encodings |
| 2 # |
| 3 # This table is derived from the "MIPS® Architecture For Programmers |
| 4 # Volume II-A: The MIPS32® Instruction Set". |
| 5 |
| 6 # This file defines the Native Client "instruction classes" assigned to every |
| 7 # possible MIPS32 instruction encoding. It is organized into a series of tables, |
| 8 # and directly parallels the MIPS Architecture Reference Manual cited above. |
| 9 # |
| 10 # Each table consists of |
| 11 # - A name, |
| 12 # - A citation in the Architecture Reference Manual, |
| 13 # - One or more columns defining bitfields to match, and |
| 14 # - One or more rows describing patterns in those bitfields. |
| 15 # |
| 16 # A leading tilde (~) negates a pattern. A hyphen (-) is short for a string of |
| 17 # don't-care bits (x). A double-quote (") indicates that a pattern is the same |
| 18 # as the row above it. |
| 19 # |
| 20 # Each row may specify a terminal instruction class ("=InstClass"), or forward |
| 21 # the reader to a different table ("->table_name"). |
| 22 # |
| 23 # If an encoding is not valid in every MIPS32 architecture rev, the instruction |
| 24 # class may indicate the rev or feature that makes the encoding valid in |
| 25 # parentheses. |
