| 33 // architecture. | |

| 35 //----------Architecture Description Register Definitions---------------------- | |
| 36 // General Registers | |
| 37 // "reg_def" name (register save type, C convention save type, | |
| 38 // ideal register type, encoding); | |
| 39 // | |
| 40 // Register Save Types: | |
| 41 // | |
| 42 // NS = No-Save: The register allocator assumes that these registers | |
| 43 // can be used without saving upon entry to the method, & | |
| 44 // that they do not need to be saved at call sites. | |
| 45 // | |
| 46 // SOC = Save-On-Call: The register allocator assumes that these registers | |
| 47 // can be used without saving upon entry to the method, | |
| 48 // but that they must be saved at call sites. | |
| 49 // These are called "volatiles" on ppc. | |
| 50 // | |
| 51 // SOE = Save-On-Entry: The register allocator assumes that these registers | |
| 52 // must be saved before using them upon entry to the | |
| 53 // method, but they do not need to be saved at call | |
| 54 // sites. | |
| 55 // These are called "nonvolatiles" on ppc. | |
| 56 // | |
| 57 // AS = Always-Save: The register allocator assumes that these registers | |
| 58 // must be saved before using them upon entry to the | |
| 59 // method, & that they must be saved at call sites. | |
| 60 // | |
| 61 // Ideal Register Type is used to determine how to save & restore a | |
| 62 // register. Op_RegI will get spilled with LoadI/StoreI, Op_RegP will get | |
| 63 // spilled with LoadP/StoreP. If the register supports both, use Op_RegI. | |
| 64 // | |
| 65 // The encoding number is the actual bit-pattern placed into the opcodes. | |
| 66 // | |
| 67 // PPC64 register definitions, based on the 64-bit PowerPC ELF ABI | |
| 68 // Supplement Version 1.7 as of 2003-10-29. | |
| 69 // | |
| 70 // For each 64-bit register we must define two registers: the register | |
| 71 // itself, e.g. R3, and a corresponding virtual other (32-bit-)'half', | |
| 72 // e.g. R3_H, which is needed by the allocator, but is not used | |
| 73 // for stores, loads, etc. | |

| 2435 // Index Register, the Scale Value, and the Offset Value of the operand when | |
| 2436 // queried. COND_INTER causes an operand to generate six functions which | |

| 5147 // Iff A == B == C, B and C are left out. | |
| 5148 // | |
| 5149 // The instructions are ordered according to the following scheme: | |
| 5150 // - loads | |
| 5151 // - load constants | |
| 5152 // - prefetch | |
| 5153 // - store | |
| 5154 // - encode/decode | |
| 5155 // - membar | |
| 5156 // - conditional moves | |
| 5157 // - compare & swap | |
| 5158 // - arithmetic and logic operations | |
| 5159 // * int: Add, Sub, Mul, Div, Mod | |
| 5160 // * int: lShift, arShift, urShift, rot | |
| 5161 // * float: Add, Sub, Mul, Div | |
| 5162 // * and, or, xor ... | |
| 5163 // - register moves: float <-> int, reg <-> stack, repl | |
| 5164 // - cast (high level type cast, XtoP, castPP, castII, not_null etc. | |
| 5165 // - conv (low level type cast requiring bit changes (sign extend etc) | |
| 5166 // - compares, range & zero checks. | |
| 5167 // - branches | |
| 5168 // - complex operations, intrinsics, min, max, replicate | |
| 5169 // - lock | |
| 5170 // - Calls | |
| 5171 // | |
