This is a question about the formal guarantees of the C++ standard. The standard points out that the rules for std::memory_order_relaxed atomic variables allow "out of thin air" / "out of the blue...

I wrote a simple multithreading programs as follows: static bool finished = false; int func() { size_t i = 0; while (!finished) ++i; return i; } int main() { auto result=std::async(std::lau...

Consider this code, where x and y are integers: if (x) y = 42; Is the following compiler transformation allowed ? int tmp = y; y = 42; if (!x) y = tmp; context: This is from Bjarne Strous...
