| 24 | /* While the ia64-opc-* set of opcode tables are easy to maintain, |
| 25 | they waste a tremendous amount of space. ia64-gen rearranges the |
| 26 | instructions into a directed acyclic graph (DAG) of instruction opcodes and |
| 27 | their possible completers, as well as compacting the set of strings used. |
| 28 | |
| 29 | The disassembler table consists of a state machine that does |
| 30 | branching based on the bits of the opcode being disassembled. The |
| 31 | state encodings have been chosen to minimize the amount of space |
| 32 | required. |
| 33 | |
| 34 | The resource table is constructed based on some text dependency tables, |
| 35 | which are also easier to maintain than the final representation. */ |
