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.

If the fast-path fails then we pass +// control to the slow-path, typically in C.
