Encoding classes are parameterized macros // used 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. Again, a // function is available to check if the constant displacement is an // oop. They use the ins_encode keyword to specify their encoding // classes (which must be a sequence of enc_class names, and their // parameters, 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.
