WebApr 24, 2024 · Introduction. Pointer aliasing in C++ inhibits vectorization and other optimizations, and, hence, performance. When the compiler has some help to know that the referenced memory locations are unique, a number of optimizations can be enabled including vectorization. This article discusses the rules of pointer aliasing and remedies …
WebJun 11, 2013 · In C/C++, the responsibility for avoiding problems is placed on developers, resulting in the strict aliasing rules. There is, by the way, a severe lack of tools which check for violations of strict aliasing (compilers warn about some violations, but these warnings are highly unreliable). Ok, back to the example: c1 contains code that we must ...
