Exception handling compiler apparatus, program, recording medium, and compiling method

摘要

Compiler apparatus, methods and systems for optimizing exception handling in a program. An example apparatus comprises an exception handler detection section for detecting, from exception handlers that catch exceptions thrown in the program, a multiple-catching exception handler that catches a plurality of different exceptions and rethrow the caught exceptions; an exception selection section for selecting a set of exceptions that are to be shifted to common processing through rethrow of the exception by the multiple-catching exception handler from among the plurality of exceptions caught by the detected multiple-catching exception handler; and an exception handler throw section for throwing a clone exception handler that catches the set of exceptions selected by the exception selection section instead of the multiple-catching exception handler and shifting it to common processing.
