	PyProfGen -- __fopen_internal
		The "call graph" shows how much time was spent in each function and its children.
		This should be identical to the number printed in the `seconds' field for this function in the flat profile.
		Called -- This is the number of times the function was called.

	Intel® VTune Performance Analyzer 8.0 for Linux* - Call Graph Limitations
		Call graph support is based on binary instrumentation, and therefore only instrumented functions are reported in the call graph results.
		Call graph results are written during the regular termination procedure of the process.
		Call graph does not support applications that use two different shared objects with the same name, even if they are located in different directories.

	GPROF
		The −c option causes the call graph of the program to be augmented by a heuristic which examines the text space of the object file and identifies function calls in the binary machine code.
		Calls to functions that were not compiled with profiling enabled are also identified, but only if symbol table entries are present for them.
		Thus the time propagated along the call graph arcs to the function’s parents is directly proportional to the number of times that arc is traversed.

	paper
		Having gathered the arcs of the call graph and timing information for an execution of the program, we are interested in attributing the time for each routine to the routines that call it.
		Calls among the members of the cycle do not propagate any time, though they are listed in the call graph profile.
		However, discovering the static call graph from the source text would require two moderately difficult steps: finding the source text for the program (which may not be available), and scanning and parsing that text, which may be in any one of several languages.

		A call graph shows not only individual methods and their profiling data, but also the parent and child method calls associated with them.
		Call graphs can be generated in plain text or html.
		Since call graphs are a bit less common than normal profiling data, here's a sample that we can walk through to get a better feel for what can do for you.

		The -c option causes the call graph of the program to be augmented by a heuristic which examines the text space of the object file and identifies function calls in the binary machine code.
		Parents or children identified via this heuristic are indicated in the call graph with call counts of 0.
		Thus the time propagated along the call graph arcs to the function's parents is directly proportional to the number of times that arc is traversed.

	Tail recursion - Wikipedia, the free encyclopedia
		When a function is called, the computer must "remember" the place it was called from, the return address, so that it can return to that location with the result once the call is complete.
		Since having a complete call graph is a daunting task for compilers, a mere tail call is usually referred to as being tail recursive.
		Using a trampoline for all function calls is rather more expensive than the normal C function call, so at least one Scheme compiler, Chicken, uses a technique first described by Henry Baker from an unpublished suggestion by Andrew Appel, in which normal C calls are used but the stack size is checked before every call.

	GNU gprof - How to Read the Call Graph (Site not responding. Last check: )
		The primary line in a call graph entry is the line that describes the function which the entry is about and gives the overall statistics for this function.

	NAGWare Fortran Tools - f95 Tools - nag_fcalls95 (Site not responding. Last check: )
		As well as the usual call graph, the tool produces an index which lists, for each program-unit, the line of the call graph on which its subgraph begins.
		If the call graph of the main program is required, ``%'' may be used as shorthand for the main program unit's name (and may be used to refer to an unnamed main program).
		This is reflected in the call graph by giving the subgraph for each unique set of procedure parameters used.

	CodeViz
		This would generate two full.graphs and two call graphs of the function kswapd() which could be compared to make sure the cdepn graph is accurate.
		With a large input graph, the longest operation for the generation of the call graph is the reading of the input file.
		It was a very rare case that a depth first search of the call graph would give a misleading view of the code o Allow multiple functions to be specified to graph.

	Python Call Graph
		pycallgraph is a Python library that creates call graphs for Python programs.
		As of version 0.4.0, there is a command line interface to pycallgraph called pycallgraph-dot.py.
		You may import pycallgraph as a module and run the trace graph within your application.

	Visualize function calls with Graphviz
		Additionally, a call trace can identify the maximum call depth of user functions, which you can then use to efficiently bind the memory that the call stack uses (an important consideration in embedded systems).
		When longer call chains are involved, it becomes more complicated to know who called whom, so a simple solution is to maintain a stack of the entry addresses.
		As the call chain is parsed from the trace file, a connectivity matrix is built that identifies which functions call which other functions.

	Template Call Graph Implementation
		Normally, the call graph and the set of instantiated classes (cInstantiatedClasses) would be computed simultaneously, but the FLEX implementation uses the class hierarchy to generate the latter.
		analyze_meta_method() is the heart of template call graph construction, calling the most important auxiliary functions and directing the generation of meta-methods and graph edges.
		Otherwise, get_method_data is called on the underlying HMethod.

	IBM Research \| \| dgrove \| A Framework for Call Graph Construction Algorithms (Site not responding. Last check: )
		A large number of call graph construction algorithms for object-oriented and functional languages have been proposed, each embodying different tradeoffs between analysis cost and call graph precision.
		In this paper, we present a unifying framework for understanding call graph construction algorithms and an empirical comparison of a representative set of algorithms.
		The costs and benefits of a number of call graph construction algorithms are empirically assessed by applying their Vortex implementation to a suite of sizeable (5,000 to 50,000 lines of code) Cecil and Java programs.

	Call Graphs (Site not responding. Last check: )
		Each node in the call graph represents a procedure defined in one of the selected files, or a procedure called by a procedure defined in the selected files.
		Figure 2 also shows a call graph for all files with "gui" in their name, but in this case the nodes are restricted to those defined within the selected files.
		The call graph in Figure 3 is derived from the same data used to derive the call graph in Figure 2, but the nodes in the call graph in Figure 3 represent files.

	egypt - create call graph from gcc RTL dump
		The two major tasks in creating a call graph are analyzing the syntax of the source code to find the function calls and laying out the graph, but Egypt actually does neither.
		Instead, it delegates the source code analysis to GCC and the graph layout to Graphviz, both of which are better at their respective jobs than egypt could ever hope to be itself.
		Egypt was going to be called rtlcg, short for RTL Call Graph, but it turned out to be one of those rare cases where ROT13'ing the name made it easier to remember and pronounce.

	DA-PL/M Call Hierarchy Graph
		Now a glance will suffice to discover all possible recursions in your code that would otherwise be hard to track, like a is calling b, b is calling c and c is calling a.
		Graph is as smart as the other parts of DA-PL/M. For example, you can edit automatically generated graphs manually to make them look just the way you want.
		You can even distinguish calls to library procedures from other calls easily, because library procedures are colored in a different customizable color.

	Task Variant Call Graph \| Sequoia (Site not responding. Last check: )
		The task variant call graph is a figure in which the parameterized variants are nodes and edges represent possible caller-callee relationships.
		Note that each subtask callsite in a task's body just refers to the "base" task name, and not to the specific variant which is being called, and hence there may be a number of task variants that may be called from any given callsite.
		Leaf tasks are at the leaves (or edges) of the graph, and the intent is that they will perform the bulk of the arithmetically-intensive computation of the Sequoia application on the target machine's processing elements.
