No, at best you saw code that expects the compiler to not apply specific optimizations that C++ doesn't suggest or enforce. It's a compiler issue, thus if anything that code needs to be compiled accordingly.
- ncmncm 7y agoNo, there are other reasons to use volatile declarations that have nothing to do with the original purpose, and that are completely unaffected by any potential effect on optimization. At the level I have seen, it is used as a simple tag to generate a type related to T that is neither T nor const T.
