27 //----------OS-DEPENDENT ENCODING BLOCK----------------------------------------------------- | |
28 // This block specifies the encoding classes used by the compiler to output | |
29 // byte streams. Encoding classes generate functions which are called by | |
30 // Machine Instruction Nodes in order to generate the bit encoding of the | |
31 // instruction. Operands specify their base encoding interface with the | |
32 // interface keyword. There are currently supported four interfaces, | |
33 // REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an | |
34 // operand to generate a function which returns its register number when | |
35 // queried. CONST_INTER causes an operand to generate a function which | |
36 // returns the value of the constant when queried. MEMORY_INTER causes an | |
37 // operand to generate four functions which return the Base Register, the | |
38 // Index Register, the Scale Value, and the Offset Value of the operand when | |
39 // queried. COND_INTER causes an operand to generate six functions which | |
40 // return the encoding code (ie - encoding bits for the instruction) | |
41 // associated with each basic boolean condition for a conditional instruction. | |
42 // Instructions specify two basic values for encoding. They use the | |
43 // ins_encode keyword to specify their encoding class (which must be one of | |
44 // the class names specified in the encoding block), and they use the | |
45 // opcode keyword to specify, in order, their primary, secondary, and | |
46 // tertiary opcode. Only the opcode sections which a particular instruction | |
47 // needs for encoding need to be specified. | |
48 encode %{ | |
49 // Build emit functions for each basic byte or larger field in the intel | |
50 // encoding scheme (opcode, rm, sib, immediate), and call them from C++ | |
51 // code in the enc_class source block. Emit functions will live in the | |
52 // main source block for now. In future, we can generalize this by | |
53 // adding a syntax that specifies the sizes of fields in an order, | |
54 // so that the adlc can build the emit functions automagically | |
