 *
 * The following rules must be kept by the code generator:
 *  - only the opcode without return value can be emitted
 *    by the code generator
 *  - the first form can be converted to the second form
 *    by adding 1 to the opcode
 *  - after the conversion the opcode must be immediately
 *    flushed, so no further changes are possible
