| 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 | |

| 2383 // byte streams. Encoding classes are parameterized macros used by | |
| 2384 // Machine Instruction Nodes in order to generate the bit encoding of the | |
| 2385 // instruction. Operands specify their base encoding interface with the | |
| 2386 // interface keyword. There are currently supported four interfaces, | |
| 2387 // REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an | |
| 2388 // operand to generate a function which returns its register number when | |
| 2389 // queried. CONST_INTER causes an operand to generate a function which | |
| 2390 // returns the value of the constant when queried. MEMORY_INTER causes an | |
| 2391 // operand to generate four functions which return the Base Register, the | |
| 2392 // Index Register, the Scale Value, and the Offset Value of the operand when | |
| 2393 // queried. COND_INTER causes an operand to generate six functions which | |
| 2394 // return the encoding code (ie - encoding bits for the instruction) | |
| 2395 // associated with each basic boolean condition for a conditional instruction. | |
| 2396 // | |
| 2397 // Instructions specify two basic values for encoding. Again, a function | |
| 2398 // is available to check if the constant displacement is an oop. They use the | |
| 2399 // ins_encode keyword to specify their encoding classes (which must be | |
| 2400 // a sequence of enc_class names, and their parameters, specified in | |
| 2401 // the encoding block), and they use the | |
| 2402 // opcode keyword to specify, in order, their primary, secondary, and | |
