CHAPTER 28 — Frame-based Linkage Convention, Variables, and Recursion

This chapter builds further on the stack-based linkage convention to create a frame-based linkage convention. A stack frame is the section of the run-time stack that holds the data of a subroutine.

The official linkage convention is much more elaborate than the convention described here but implements the same ideas.

Chapter Topics:

Stack frames and the frame pointer
Local variables
Simplified Frame-based Linkage Convention
Compiler optimizations
Recursion
Storage classes: static, automatic, dynamic
Entry points

QUESTION 1:

(Thought Question:) What is a local variable in a higher level language?
