5.11.1 Call Graph Information
A call graph is produced for chip types and memory models that use a compiled stack, rather than a
hardware stack, to facilitate parameter passing between functions and auto variables defined within
a function. When a compiled stack is used, functions are not re-entrant since the function will use a
fixed area of memory for its local objects (parameters/auto variables). A function called foo(), for
example, will use symbols like ?_foo for parameters and ?a_foo for auto variables. Compilers such
as the PIC, 6805 and V8 use compiled stacks. The 8051 compiler uses a compiled stack in small and
medium memory models. The call graph shows information relating to the placement of function
parameters and auto variables by the linker. A typical call graph may look something like:
