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.
68 // Now that allocator is better, turn on RSI and RDI as SOE registers.

2120 // output byte streams. Encoding classes are parameterized macros
2121 // used by Machine Instruction Nodes in order to generate the bit
2122 // encoding of the instruction. Operands specify their base encoding
2123 // interface with the interface keyword. There are currently
2124 // supported four interfaces, REG_INTER, CONST_INTER, MEMORY_INTER, &
2125 // COND_INTER. REG_INTER causes an operand to generate a function
2126 // which returns its register number when queried. CONST_INTER causes
2127 // an operand to generate a function which returns the value of the
2128 // constant when queried. MEMORY_INTER causes an operand to generate
2129 // four functions which return the Base Register, the Index Register,
2130 // the Scale Value, and the Offset Value of the operand when queried.
2131 // COND_INTER causes an operand to generate six functions which return
2132 // the encoding code (ie - encoding bits for the instruction)
2133 // associated with each basic boolean condition for a conditional
2134 // instruction.
2135 //
2136 // Instructions specify two basic values for encoding. Again, a
2137 // function is available to check if the constant displacement is an
2138 // oop. They use the ins_encode keyword to specify their encoding
2139 // classes (which must be a sequence of enc_class names, and their
2140 // parameters, specified in the encoding block), and they use the
2141 // opcode keyword to specify, in order, their primary, secondary, and
