30 //----------REGISTER DEFINITION BLOCK------------------------------------------ | |
31 // This information is used by the matcher and the register allocator to | |
32 // describe individual registers and classes of registers within the target | |
33 // architecture. | |
34 register %{ | |
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. | |

259 // Specify priority of register selection within phases of register | |
260 // allocation. Highest priority is first. A useful heuristic is to | |
261 // give registers a low priority when they are required by machine | |
262 // instructions, like EAX and EDX on I486, and choose no-save registers | |
263 // before save-on-call, & save-on-call before save-on-entry. Registers | |
264 // which participate in fixed calling sequences should come last. | |
265 // Registers which are used as pairs must fall on an even boundary. | |
266 | |
267 // It's worth about 1% on SPEC geomean to get this right. | |
268 | |
269 // Chunk0, chunk1, and chunk2 form the MachRegisterNumbers enumeration | |
270 // in adGlobals_ppc64.hpp which defines the <register>_num values, e.g. | |
271 // R3_num. Therefore, R3_num may not be (and in reality is not) | |
272 // the same as R3->encoding()! Furthermore, we cannot make any | |
273 // assumptions on ordering, e.g. R3_num may be less than R2_num. | |

2382 // operand to generate four functions which return the Base Register, the | |
2383 // Index Register, the Scale Value, and the Offset Value of the operand when | |
2384 // queried. COND_INTER causes an operand to generate six functions which | |
