int vs const int&

two issues that are not present with values lifetime and aliasing . Just as an example one place where this anti pattern is applied.. referenced by a const ref can change e.g. because of aliasing and can even get out of existence while you are using it lifetime.. for big classes. But you should always think about aliasing and lifetime issues when using references because under the..

very likely possibility that this alignment causes false aliasing in the load store units or the cache. I Googled around for this.. Intel actually has a hardware counter for partial address aliasing stalls http software.intel.com sites products documentation.. is due to the alignment which most likely causes false aliasing stalls in the processor load store units. However in order for..
