| 183 // single float registers. In each pair, ADLC-assigned register numbers | |
| 184 // must be adjacent, with the lower number even. Finally, when the | |

| 187 | |
| 188 // These definitions specify the actual bit encodings of the sparc | |
| 189 // double fp register numbers. FloatRegisterImpl in register_sparc.hpp | |
| 190 // wants 0-63, so we have to convert every time we want to use fp regs | |

| 10808 // These must follow all instruction definitions as they use the names | |
| 10809 // defined in the instructions definitions. | |
| 10810 // | |

| 10823 // | |
| 10824 // All peephole optimizations can be turned off using -XX:-OptoPeephole | |
| 10825 // | |
| 10826 // Each peephole rule is given an identifying number starting with zero and | |
| 10827 // increasing by one in the order seen by the parser. An individual peephole | |
| 10828 // can be enabled, and all others disabled, by using -XX:OptoPeepholeAt=# | |
| 10829 // on the command-line. | |
| 10830 // | |
| 10831 // ---------CURRENT LIMITATIONS---------------------------------------------- | |
| 10832 // | |
| 10833 // Only match adjacent instructions in same basic block | |
| 10834 // Only equality constraints | |
| 10835 // Only constraints between operands, not (0.dest_reg == EAX_enc) | |
| 10836 // Only one replacement instruction | |
| 10837 // | |
