But what if the instructions are reordered so the flag is set first volatile does guarantee the first point... access to non volatile data. Those accesses can still be reordered relative to the volatile ones. The solution to preventing reordering.. to the compiler and the CPU that no memory access may be reordered across this point . Placing such barriers around our volatile..
