Linker and Utilities
5.8.2.2 Call Graph Information
A call graph is produced and displayed in the map file for target devices and memory models that use
a compiled stack to facilitate parameter passing between functions and auto variables. See Section
5.7
which is primarily used to allow overlapping of functions’ APBs. The following information can be
obtained from studying the call graph:
These features are discussed below.
dard version compilers, however there are differences. A typical Pro compiler call graph may look
something like:
for more detailed information on compiled stack operation.
The call graph in the map file shows the information collated and interpreted by the linker,
The call graph produced by Pro versions compilers is very similar to that produced by Stan-
The functions in the program that are “root” nodes marking the top of a call tree, and which
are not directly called;
The functions that the linker deemed were called, or may have been called, during program
execution;
The program’s hierarchy of function calls;
The size of the auto and parameter areas within each function’s APB;
The offset of each function’s APB within the program’s auto/parameter psect;
Which functions’ APBs are consuming memory not overlapped by the APB of any other
function;
Which functions are called indirectly;
Which functions are called as part of a parameter expression for another function;
Estimated call tree depth.
