 1587 // output byte streams.  Encoding classes are parameterized macros
 1588 // used by Machine Instruction Nodes in order to generate the bit
 1589 // encoding of the instruction.  Operands specify their base encoding
 1590 // interface with the interface keyword.  There are currently
 1591 // supported four interfaces, REG_INTER, CONST_INTER, MEMORY_INTER, &
 1592 // COND_INTER.  REG_INTER causes an operand to generate a function
 1593 // which returns its register number when queried.  CONST_INTER causes
 1594 // an operand to generate a function which returns the value of the
 1595 // constant when queried.  MEMORY_INTER causes an operand to generate
 1596 // four functions which return the Base Register, the Index Register,
 1597 // the Scale Value, and the Offset Value of the operand when queried.
 1598 // COND_INTER causes an operand to generate six functions which return
 1599 // the encoding code (ie - encoding bits for the instruction)
 1600 // associated with each basic boolean condition for a conditional
 1601 // instruction.
 1602 //
 1603 // Instructions specify two basic values for encoding.  Again, a
 1604 // function is available to check if the constant displacement is an
 1605 // oop. They use the ins_encode keyword to specify their encoding
 1606 // classes (which must be a sequence of enc_class names, and their
 1607 // parameters, specified in the encoding block), and they use the
 1608 // opcode keyword to specify, in order, their primary, secondary, and
 1609 // tertiary opcode.  Only the opcode sections which a particular
