Towards restrict-like aliasing semantics for C++

by Hal Finkel, Hubert Tong, Chandler Carruth, Clark Nelson, Daveed Vandevoode, Michael Wong


This paper is a follow-on to N3635 after a design discussion with many compiler implementers at Issaquah, and afterwards by telecon, and specifically proposes a new alias_set attribute as a way to partition type-based aliasing to enable more fine grain control, effectively giving C++ a more complete restrict-like aliasing syntax and semantics.
