| 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. | |

| 1681 // This block specifies the encoding classes used by the compiler to | |
| 1682 // output byte streams. Encoding classes are parameterized macros | |
| 1683 // used by Machine Instruction Nodes in order to generate the bit | |
| 1684 // encoding of the instruction. Operands specify their base encoding | |
| 1685 // interface with the interface keyword. There are currently | |
| 1686 // supported four interfaces, REG_INTER, CONST_INTER, MEMORY_INTER, & | |
| 1687 // COND_INTER. REG_INTER causes an operand to generate a function | |
| 1688 // which returns its register number when queried. CONST_INTER causes | |
| 1689 // an operand to generate a function which returns the value of the | |
| 1690 // constant when queried. MEMORY_INTER causes an operand to generate | |
| 1691 // four functions which return the Base Register, the Index Register, | |
| 1692 // the Scale Value, and the Offset Value of the operand when queried. | |
| 1693 // COND_INTER causes an operand to generate six functions which return | |
| 1694 // the encoding code (ie - encoding bits for the instruction) | |
| 1695 // associated with each basic boolean condition for a conditional | |
| 1696 // instruction. | |

| 1698 // Instructions specify two basic values for encoding. Again, a | |
| 1699 // function is available to check if the constant displacement is an | |
| 1700 // oop. They use the ins_encode keyword to specify their encoding | |
| 1701 // classes (which must be a sequence of enc_class names, and their | |
| 1702 // parameters, specified in the encoding block), and they use the | |
| 1703 // opcode keyword to specify, in order, their primary, secondary, and | |
