4.9.23 Fnbreak Directive

The FNBREAK routine1,routine2 directive is used to break links in the call graph information produced by the linker.

It states that any calls to routine1 in trees other than the tree rooted at routine2 should not be considered when checking for routines that appear in multiple call graphs. Memory for routine1's compiled stack objects will only be assigned in the graph for the routine rooted at routine2.
