21    * For: move-result, move-result-object

23    * Description: Move the single-word non-object result of the most
24    *              recent method invocation into the indicated register. This
25    *              must be done as the instruction immediately after a
26    *              method invocation whose (single-word, non-object) result
27    *              is not to be ignored; anywhere else is invalid.
