7.1.3 C: Specify Call Graph Style

The -Ctype option controls what type of call graph is printed in the map file. The available types are shown in the table.
Table 7-2. Call graph types
Type Produces
n No call graph.
c Only critical paths in the call graph.
s Standard, short-form call graph (default).
f Full call graph.

The call graph is generated by the linker, primarily for the purposes of allocating memory to objects in the compiled stack. Those routines defining stack objects that are not overlaid with other stack objects and that are hence contributing to the program's data memory usage are considered as being on a critical path.
