Detailed Description

During building a callgraph_container we store all caller/callee relationship in this container.

An "arc" is simply a description of a call from one function to another.

Member Function Documentation

void arc_recorder::add	(	symbol_entry const &	caller,
		symbol_entry const *	callee,
		count_array_t const &	arc_count
	)

Add a symbol arc.

Parameters:

	caller	The calling symbol
	callee	The called symbol
	arc_count	profile data for the arcs

If the callee is NULL, only the caller is added to the main list. This is used to initially populate the recorder with the symbols.

Here is the caller graph for this function:

void arc_recorder::process	(	count_array_t	total,
		double	threshold,
		string_filter const &	filter
	)

After population, build the final output, and do thresholding.
