ABSTRACT:
A method and apparatus allows a compiler to optimize code in the presence of exception handlers. According to a first embodiment, arcs are added to a control flow graph, prior to performing global optimizations, to account for exception handling code. According to the second embodiment, information relating to control flow to exception handlers is provided in pseudo-references in the code, which allows the compiler to determine how to appropriately optimize the code.
