29 // describe individual registers and classes of registers within the target | |
30 // archtecture. | |

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. | |
41 // | |
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 | |

55 // Ideal Register Type is used to determine how to save & restore a | |
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. | |

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. | |

1999 // operand to generate a function which returns its register number when | |
2000 // queried. CONST_INTER causes an operand to generate a function which | |

2002 // operand to generate four functions which return the Base Register, the | |
2003 // Index Register, the Scale Value, and the Offset Value of the operand when | |
2004 // queried. COND_INTER causes an operand to generate six functions which | |

9215 // for LT, LE, or EQ. For a simple LT test we can check just the sign bit. | |

9217 // the operands (yielding a GE test) and then negating; negate again for the | |
9218 // GT test. The EQ test is done by ORcc'ing the high and low halves, and the | |
9219 // NE test is negated from that. | |
9220 | |
9221 // Due to a shortcoming in the ADLC, it mixes up expressions like: | |
9222 // (foo (CmpI (CmpL X Y) 0)) and (bar (CmpI (CmpL X 0L) 0)). Note the | |
9223 // difference between 'Y' and '0L'. The tree-matches for the CmpI sections | |
9224 // are collapsed internally in the ADLC's dfa-gen code. The match for | |
9225 // (CmpI (CmpL X Y) 0) is silently replaced with (CmpI (CmpL X 0L) 0) and the | |
9226 // foo match ends up with the wrong leaf. One fix is to not match both | |
9227 // reg-reg and reg-zero forms of long-compare. This is unfortunate because | |

9968 //----------PEEPHOLE RULES----------------------------------------------------- | |
9969 // These must follow all instruction definitions as they use the names | |
9970 // defined in the instructions definitions. | |
9971 // | |
605 | 9972 // peepmatch ( root_instr_name [preceding_instruction]* ); |
0 | 9973 // |
9974 // peepconstraint %{ | |

9983 // ---------VM FLAGS--------------------------------------------------------- | |
9984 // | |
9985 // All peephole optimizations can be turned off using -XX:-OptoPeephole | |

9987 // Each peephole rule is given an identifying number starting with zero and | |
9988 // increasing by one in the order seen by the parser. An individual peephole | |

9990 // on the command-line. | |
9991 // | |
9992 // ---------CURRENT LIMITATIONS---------------------------------------------- | |
9993 // | |
9994 // Only match adjacent instructions in same basic block | |
9995 // Only equality constraints | |
9996 // Only constraints between operands, not (0.dest_reg == EAX_enc) | |
9997 // Only one replacement instruction | |
