-//----------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
