Methods and apparatuses for automatic type checking via poisoned pointers
Abstract:
A method and an apparatus that modify pointer values pointing to typed data with type information are described. The type information can be automatically checked against the typed data leveraging hardware based safety check mechanisms when performing memory access operations to the typed data via the modified pointer values. As a result, hardware built in logic can be used for a broad class of programming language safety check when executing software codes using modified pointers that are subject to the safety check without executing compare and branch instructions in the software codes.
