    1.14 -//----------OS-DEPENDENT ENCODING BLOCK-----------------------------------------------------
    1.15 -// This block specifies the encoding classes used by the compiler to output
    1.16 -// byte streams.  Encoding classes generate functions which are called by
    1.17 -// Machine Instruction Nodes in order to generate the bit encoding of the
    1.18 -// instruction.  Operands specify their base encoding interface with the
    1.19 -// interface keyword.  There are currently supported four interfaces,
    1.20 -// REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER.  REG_INTER causes an
    1.21 -// operand to generate a function which returns its register number when
    1.22 -// queried.   CONST_INTER causes an operand to generate a function which
    1.23 -// returns the value of the constant when queried.  MEMORY_INTER causes an
    1.24 -// operand to generate four functions which return the Base Register, the
    1.25 -// Index Register, the Scale Value, and the Offset Value of the operand when
    1.26 -// queried.  COND_INTER causes an operand to generate six functions which
    1.27 -// return the encoding code (ie - encoding bits for the instruction)
    1.28 -// associated with each basic boolean condition for a conditional instruction.
    1.29 -// Instructions specify two basic values for encoding.  They use the
    1.30 -// ins_encode keyword to specify their encoding class (which must be one of
    1.31 -// the class names specified in the encoding block), and they use the
    1.32 -// opcode keyword to specify, in order, their primary, secondary, and
    1.33 -// tertiary opcode.  Only the opcode sections which a particular instruction
    1.34 -// needs for encoding need to be specified.
    1.35 -encode %{
    1.36 -  // Build emit functions for each basic byte or larger field in the intel

    1.39 -  // main source block for now.  In future, we can generalize this by
