Computer program products for sibling call processing, computer systems and methods implemented by computers

摘要

A computer program product, a computer system, and a computer-implemented method for sibling call processing are provided. An optimization for sibling calls is provided. The sibling caller is marked to indicate that it may call a sibling routine or may call an external sibling routine. Based on this marking, certain processing is performed to facilitate the use of the sibling call, especially if the sibling routine being called is external to the caller. [Selection diagram] FIG.
