+//----------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
