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