- This paper establishes a precise model for pointer provenance and alias analysis in C. The direction it lays out has been approved in principle by the ISO C WG14 committee and the Undefined Behaviour group of the ISO C++ WG21 committee, and the ISO process for creating an associated Technical Specification is underway, http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2577.pdf. This will clarify what optimisations compilers can do, and what properties programmers can depend on, for the critical infrastructure that is the C language.
