octave: libinterp/corefcn/stack-frame.h annotate

annotate libinterp/corefcn/stack-frame.h @ 28793:c5953e65c6aa stable

track direct caller in stack frames * stack-frame.h, stack-frame.cc (stack_frame::m_parent_link): New data member to track direct parent, not just user-defined function, script, or scope frames as m_static_link does. (stack_frame::parent_link): New function. (stack_frame::stack_frame): Accept parent_link argument. Change all uses. (stack_frame::create): Accept parent_link argument. Change all uses. * call-stack.cc (call_stack::pop): Set m_curr_frame to parent_link, not static_link.
