CONTROL FLOW-BASED APPROACH IN IMPLEMENTING EXCEPTION HANDLING ON A GRAPHICS PROCESSING UNIT

摘要

A function in source code is processed by a compiler for execution on a graphics processing unit, wherein the function includes an exception handling structure. An exception raising block is converted into a first control flow and an exception handler block is converted into a second control flow. The first control flow includes setting an exception raised indicator and finding an exception handler to process the raised exception. The exception raised indicator remains set until an appropriate exception handler is found. The second control flow includes clearing the exception raised indicator and processing the exception.
