// 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. |

// 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. |

|
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. |

//----------ENCODING BLOCK----------------------------------------------------- |
|
2303 |
// This block specifies the encoding classes used by the compiler to output |
|
2304 |
// byte streams. Encoding classes are parameterized macros used by |
|
2305 |
// Machine Instruction Nodes in order to generate the bit encoding of the |
|
2306 |
// instruction. Operands specify their base encoding interface with the |
|
2307 |
// interface keyword. There are currently supported four interfaces, |
|
2308 |
// REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an |
|
2309 |
// operand to generate a function which returns its register number when |
|
2310 |
// queried. CONST_INTER causes an operand to generate a function which |
|
2311 |
// returns the value of the constant when queried. MEMORY_INTER causes an |
|
2312 |
// operand to generate four functions which return the Base Register, the |
|
2313 |
// Index Register, the Scale Value, and the Offset Value of the operand when |
|
2314 |
// queried. COND_INTER causes an operand to generate six functions which |
|
2315 |
// return the encoding code (ie - encoding bits for the instruction) |
|
2316 |
// associated with each basic boolean condition for a conditional instruction. |
|
2317 |
// |
|
2318 |
// Instructions specify two basic values for encoding. Again, a function |
|
2319 |
// is available to check if the constant displacement is an oop. They use the |
|
2320 |
// ins_encode keyword to specify their encoding classes (which must be |
|
2321 |
// a sequence of enc_class names, and their parameters, specified in |
|
2322 |
// the encoding block), and they use the |
|
2323 |
// opcode keyword to specify, in order, their primary, secondary, and |

// Naming of instructions: |

// opA_operB / opA_operB_operC: |
|
4958 |
// Operation 'op' with one or two source operands 'oper'. Result |

// type is A, source operand types are B and C. |
|
4960 |
// Iff A == B == C, B and C are left out. |
|
4961 |
// |
|
4962 |
// The instructions are ordered according to the following scheme: |
|
4963 |
// - loads |
|
4964 |
// - load constants |
|
4965 |
// - prefetch |
|
4966 |
// - store |
|
4967 |
// - encode/decode |
|
4968 |
// - membar |
|
4969 |
// - conditional moves |
|
4970 |
// - compare & swap |
|
4971 |
// - arithmetic and logic operations |
|
4972 |
// * int: Add, Sub, Mul, Div, Mod |
|
4973 |
// * int: lShift, arShift, urShift, rot |
|
4974 |
// * float: Add, Sub, Mul, Div |
|
4975 |
// * and, or, xor ... |
|
4976 |
// - register moves: float <-> int, reg <-> stack, repl |
|
4977 |
// - cast (high level type cast, XtoP, castPP, castII, not_null etc. |
|
4978 |
// - conv (low level type cast requiring bit changes (sign extend etc) |
|
4979 |
// - compares, range & zero checks. |
|
4980 |
// - branches |
|
4981 |
// - complex operations, intrinsics, min, max, replicate |
|
4982 |
// - lock |
|
4983 |
// - Calls |
|
4984 |
// |
|
