Abstract
Fast exception processing is disclosed. In one embodiment, a system includes a splice cache, an exception logic, and an instrumentation mechanism. The splice cache contains one or more lightweight handlers. The exception logic is coupled to the splice cache and determines whether the corresponding lightweight handler for an exception is located in the splice cache. The instrumentation mechanism is coupled to the splice cache. The instrumentation mechanism inserts the lightweight handler into an execution stream.
