> In C, the ‘minimal’ part is called the ‘scope’. Variables are always destroyed in the inverse order to the order in which they are created and so it’s always trivial to translate each into a stack save followed by an alloca when the variable comes into scope and a stack restore when the variable goes out of scope. > >> what would happen if stack safe/remove would be neglected?
