| 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. | |

| 34 // General Registers | |
| 35 // "reg_def" name ( register save type, C convention save type, | |
| 36 // ideal register type, encoding ); | |
| 37 // Register Save Types: | |
| 38 // | |
| 39 // NS = No-Save: The register allocator assumes that these registers | |
| 40 // can be used without saving upon entry to the method, & | |
| 41 // that they do not need to be saved at call sites. | |
| 42 // | |
| 43 // SOC = Save-On-Call: The register allocator assumes that these registers | |
| 44 // can be used without saving upon entry to the method, | |
| 45 // but that they must be saved at call sites. | |
| 46 // | |
| 47 // SOE = Save-On-Entry: The register allocator assumes that these registers | |
| 48 // must be saved before using them upon entry to the | |
| 49 // method, but they do not need to be saved at call | |
| 50 // sites. | |
| 51 // | |
| 52 // AS = Always-Save: The register allocator assumes that these registers | |
| 53 // must be saved before using them upon entry to the | |
| 54 // method, & that they must be saved at call sites. | |
| 55 // | |
| 56 // Ideal Register Type is used to determine how to save & restore a | |
| 57 // register. Op_RegI will get spilled with LoadI/StoreI, Op_RegP will get | |
| 58 // spilled with LoadP/StoreP. If the register supports both, use Op_RegI. | |
| 59 // | |
| 60 // The encoding number is the actual bit-pattern placed into the opcodes. | |
| 61 | |
| 62 // General Registers | |
| 63 // R8-R15 must be encoded with REX. (RSP, RBP, RSI, RDI need REX when | |
| 64 // used as byte registers) | |
| 65 | |
| 66 // Previously set RBX, RSI, and RDI as save-on-entry for java code | |
| 67 // Turn off SOE in java-code due to frequent use of uncommon-traps. | |
| 68 // Now that allocator is better, turn on RSI and RDI as SOE registers. | |

| 2118 //----------ENCODING BLOCK----------------------------------------------------- | |
| 2119 // This block specifies the encoding classes used by the compiler to | |
| 2120 // output byte streams. Encoding classes are parameterized macros | |
| 2121 // used by Machine Instruction Nodes in order to generate the bit | |
| 2122 // encoding of the instruction. Operands specify their base encoding | |
| 2123 // interface with the interface keyword. There are currently | |
| 2124 // supported four interfaces, REG_INTER, CONST_INTER, MEMORY_INTER, & | |
| 2125 // COND_INTER. REG_INTER causes an operand to generate a function | |
| 2126 // which returns its register number when queried. CONST_INTER causes | |
| 2127 // an operand to generate a function which returns the value of the | |
| 2128 // constant when queried. MEMORY_INTER causes an operand to generate | |
| 2129 // four functions which return the Base Register, the Index Register, | |
| 2130 // the Scale Value, and the Offset Value of the operand when queried. | |
| 2131 // COND_INTER causes an operand to generate six functions which return | |
| 2132 // the encoding code (ie - encoding bits for the instruction) | |
| 2133 // associated with each basic boolean condition for a conditional | |
| 2134 // instruction. | |
| 2135 // | |
| 2136 // Instructions specify two basic values for encoding. Again, a | |
| 2137 // function is available to check if the constant displacement is an | |
| 2138 // oop. They use the ins_encode keyword to specify their encoding | |
| 2139 // classes (which must be a sequence of enc_class names, and their | |
| 2140 // parameters, specified in the encoding block), and they use the | |
| 2141 // opcode keyword to specify, in order, their primary, secondary, and | |
| 2142 // tertiary opcode. Only the opcode sections which a particular | |
| 2143 // instruction needs for encoding need to be specified. | |
