// call_stack.h: A call stack comprised of stack frames.
//
// This class manages a vector of stack frames. It is used instead of
// exposing the vector directly to allow the CallStack to own StackFrame
// pointers without having to publicly export the linked_ptr class. A
// CallStack must be composed of pointers instead of objects to allow for
// CPU-specific StackFrame subclasses.
//
// By convention, the stack frame at index 0 is the innermost callee frame,
// and the frame at the highest index in a call stack is the outermost
// caller. CallStack only allows stacks to be built by pushing frames,
// beginning with the innermost callee frame.
