Well, if that is the case, then , how advantageous would be considering cache locality for such register spilled values, so that instructions that require spilled values do not cause cache miss. Does the famous register allocation by graph coloring algorithm takes care of cache locality for spilled values. regards Umar Janjua <Umar.Janjua@xxxxxxxxxxxx> writes: > During register allocation , when certain virtual registers are decided to be > spilled to memory, is there a specific scheme/strategy on the basis of which > the spilled values are laid out on memory. Well, yes and no. The spilled values are put into the stack frame. The space is allocated by calls to assign_stack_local(). But there is no predictable ordering of the spilled pseudo-registers, if that is what you mean. The registers are spilled as needed as the compiler works through the instructions.
