Activation Tree
We can create a tree (known as activation tree) to show the way control enters and leaves activations. In an activation tree
- Each node represents an activation of a procedure.
- The root represents the activation of the main program.
- The node a is a parent of the node b if and only if the control flows from a
to b.
- The node a is left to the node b if the lifetime of a occurs before the brorirne
of b.
