27 //----------REGISTER DEFINITION BLOCK------------------------------------------ | |
28 // This information is used by the matcher and the register allocator to | |
29 // describe individual registers and classes of registers within the target | |
30 // archtecture. | |
31 register %{ | |
32 //----------Architecture Description Register Definitions---------------------- | |
33 // General Registers | |
34 // "reg_def" name ( register save type, C convention save type, | |
35 // ideal register type, encoding, vm name ); | |
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. | |
50 // | |
51 // AS = Always-Save: The register allocator assumes that these registers | |
52 // must be saved before using them upon entry to the | |
53 // method, & that they must be saved at call sites. | |
54 // | |
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. | |
58 // | |
59 // The encoding number is the actual bit-pattern placed into the opcodes. | |

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. | |

2105 // This block specifies the encoding classes used by the compiler to output | |
2106 // byte streams. Encoding classes are parameterized macros used by | |
2107 // Machine Instruction Nodes in order to generate the bit encoding of the | |
2108 // instruction. Operands specify their base encoding interface with the | |
2109 // interface keyword. There are currently supported four interfaces, | |
2110 // REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an | |
2111 // operand to generate a function which returns its register number when | |
2112 // queried. CONST_INTER causes an operand to generate a function which | |
2113 // returns the value of the constant when queried. MEMORY_INTER causes an | |
2114 // operand to generate four functions which return the Base Register, the | |
2115 // Index Register, the Scale Value, and the Offset Value of the operand when | |
2116 // queried. COND_INTER causes an operand to generate six functions which | |
2117 // return the encoding code (ie - encoding bits for the instruction) | |
2118 // associated with each basic boolean condition for a conditional instruction. | |
2119 // | |
2120 // Instructions specify two basic values for encoding. Again, a function | |
2121 // is available to check if the constant displacement is an oop. They use the | |
2122 // ins_encode keyword to specify their encoding classes (which must be | |
2123 // a sequence of enc_class names, and their parameters, specified in | |
2124 // the encoding block), and they use the | |
2125 // opcode keyword to specify, in order, their primary, secondary, and | |

9846 // for LT, LE, or EQ. For a simple LT test we can check just the sign bit. | |
