Abstract
A system for exception handling is configured to, in response to detection of an exception during a function call, search for an exception handler to handle the detected exception by unwinding a stack across a plurality of frames. A binary includes functions associated with one of a first application binary interface (ABI) or a second ABI. The stack includes a transition frame created between frames of the first ABI and the second ABI during execution of the binaries. The system is configured to detect the transition frame in the stack when encountering a change from a frame of one ABI to a frame of another ABI, and translate an interface context therebetween to handle the exception.
