Edit Question
Title
Body
Just wondering: When I add restrict to a pointer, I tell the compiler that the pointer is not an alias for another pointer. Let's assume I have a function like: // Constructed example void foo (float* result, const float* a, const float* b, const size_t size) { for (size_t i = 0; i < size; ++i) { result [i] = a [0] * b [i]; } } If the compiler has to assume that result might overlap with a , it has to refetch a each time. But, as a is marked const , the compiler could also assume that a is fixed, and hence fetching it once is ok. Question is, in a situation like this, what is the recommend way to work with restrict? I surely don't want the compiler to refetch a each time, but I couldn't find good information about how restrict is supposed to work here.
