| 36 // Register Save Types: | |
| 37 // | |
| 38 // NS = No-Save: The register allocator assumes that these registers | |
| 39 // can be used without saving upon entry to the method, & | |
| 40 // that they do not need to be saved at call sites. | |

| 42 // SOC = Save-On-Call: The register allocator assumes that these registers | |
| 43 // can be used without saving upon entry to the method, | |
| 44 // but that they must be saved at call sites. | |
| 45 // | |
| 46 // SOE = Save-On-Entry: The register allocator assumes that these registers | |
| 47 // must be saved before using them upon entry to the | |
| 48 // method, but they do not need to be saved at call | |
| 49 // sites. | |

| 52 // must be saved before using them upon entry to the | |

| 56 // register. Op_RegI will get spilled with LoadI/StoreI, Op_RegP will get | |
| 57 // spilled with LoadP/StoreP. If the register supports both, use Op_RegI. | |

| 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. | |

| 2116 // queried. CONST_INTER causes an operand to generate a function which | |
| 2117 // returns the value of the constant when queried. MEMORY_INTER causes an | |
| 2118 // operand to generate four functions which return the Base Register, the | |
| 2119 // Index Register, the Scale Value, and the Offset Value of the operand when | |
| 2120 // queried. COND_INTER causes an operand to generate six functions which | |

| 11118 // These must follow all instruction definitions as they use the names | |
| 11119 // defined in the instructions definitions. | |
| 11120 // | |
| 605 | 11121 // peepmatch ( root_instr_name [preceding_instruction]* ); |
| 0 | 11122 // |
| 11123 // peepconstraint %{ | |
| 11124 // (instruction_number.operand_name relational_op instruction_number.operand_name | |
| 11125 // [, ...] ); | |
| 11126 // // instruction numbers are zero-based using left to right order in peepmatch | |
| 11127 // | |
| 11128 // peepreplace ( instr_name ( [instruction_number.operand_name]* ) ); | |
| 11129 // // provide an instruction_number.operand_name for each operand that appears | |
| 11130 // // in the replacement instruction's match rule | |
| 11131 // | |
| 11132 // ---------VM FLAGS--------------------------------------------------------- | |
| 11133 // | |
| 11134 // All peephole optimizations can be turned off using -XX:-OptoPeephole | |
| 11135 // | |
| 11136 // Each peephole rule is given an identifying number starting with zero and | |
| 11137 // increasing by one in the order seen by the parser. An individual peephole | |
| 11138 // can be enabled, and all others disabled, by using -XX:OptoPeepholeAt=# | |
| 11139 // on the command-line. | |
| 11140 // | |
| 11141 // ---------CURRENT LIMITATIONS---------------------------------------------- | |
| 11142 // | |
| 11143 // Only match adjacent instructions in same basic block | |
| 11144 // Only equality constraints | |
| 11145 // Only constraints between operands, not (0.dest_reg == EAX_enc) | |
| 11146 // Only one replacement instruction | |
| 11147 // | |
| 11148 // ---------EXAMPLE---------------------------------------------------------- | |
