class EscapeEnumerator

Declaration

class EscapeEnumerator { /* full declaration omitted */ };

Description

EscapeEnumerator - This is a little algorithm to find all escape points from a function so that "finally"-style code can be inserted. In addition to finding the existing return and unwind instructions, it also (if necessary) transforms any call instructions into invokes and sends them to a landing pad.
