36 // Register Save Types:
37 //
38 // NS = No-Save: The register allocator assumes that these registers
39 // can be used without saving upon entry to the method, &
40 // that they do not need to be saved at call sites.
41 //
42 // SOC = Save-On-Call: The register allocator assumes that these registers
43 // can be used without saving upon entry to the method,
44 // but that they must be saved at call sites.
45 //
46 // SOE = Save-On-Entry: The register allocator assumes that these registers
47 // must be saved before using them upon entry to the
48 // method, but they do not need to be saved at call
49 // sites.
50 //
51 // AS = Always-Save: The register allocator assumes that these registers
52 // must be saved before using them upon entry to the
53 // method, & that they must be saved at call sites.
54 //
55 // Ideal Register Type is used to determine how to save & restore a
56 // register. Op_RegI will get spilled with LoadI/StoreI, Op_RegP will get
57 // spilled with LoadP/StoreP. If the register supports both, use Op_RegI.

1895 // Machine Instruction Nodes in order to generate the bit encoding of the
1896 // instruction. Operands specify their base encoding interface with the
1897 // interface keyword. There are currently supported four interfaces,
1898 // REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an
1899 // operand to generate a function which returns its register number when
1900 // queried. CONST_INTER causes an operand to generate a function which
1901 // returns the value of the constant when queried. MEMORY_INTER causes an
1902 // operand to generate four functions which return the Base Register, the
1903 // Index Register, the Scale Value, and the Offset Value of the operand when
1904 // queried. COND_INTER causes an operand to generate six functions which
1905 // return the encoding code (ie - encoding bits for the instruction)
1906 // associated with each basic boolean condition for a conditional instruction.
1907 //
1908 // Instructions specify two basic values for encoding. Again, a function
1909 // is available to check if the constant displacement is an oop. They use the
1910 // ins_encode keyword to specify their encoding classes (which must be
1911 // a sequence of enc_class names, and their parameters, specified in
1912 // the encoding block), and they use the
