| 43 // can be used without saving upon entry to the method, | |
| 44 // but that they must be saved at call sites. | |

| 180 // Double Registers | |
| 181 // The rules of ADL require that double registers be defined in pairs. | |
| 182 // Each pair must be two 32-bit values, but not necessarily a pair of | |
| 183 // single float registers. In each pair, ADLC-assigned register numbers | |
| 184 // must be adjacent, with the lower number even. Finally, when the | |
| 185 // CPU stores such a register pair to memory, the word associated with | |
| 186 // the lower ADLC-assigned number must be stored to the lower address. | |
| 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 | |
| 191 // with the macroassembler, using reg_to_DoubleFloatRegister_object(). | |
| 605 | 192 // 255 is a flag meaning "don't go here". |
| 0 | 193 // I believe we can't handle callee-save doubles D32 and up until |
| 194 // the place in the sparc stack crawler that asserts on the 255 is | |
| 195 // fixed up. | |
