The ModulePass
which wraps up a CallGraph
and the logic to build it.
This class exposes both the interface to the call graph container and the module pass which runs over a module of IR and produces the call graph. The call graph interface is entirelly a wrapper around a CallGraph
object which is stored internally for each module.

getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job.
If a pass specifies that it uses a particular analysis result to this function, it can then use the getAnalysis<AnalysisType>() function, below.

print - Print out the internal state of the pass.
This is called by Analyze to print out the contents of an analysis. Otherwise it is not necessary to implement this method. Beware that the module pointer MAY be null. This automatically forwards to a virtual function that does not provide the Module* in case the analysis doesn't need it it can just be ignored.

releaseMemory() - This member can be implemented by a pass if it wants to be able to release its memory when it is no longer needed.
The default behavior of passes is to hold onto memory for the entire duration of their lifetime (which is the entire compile time). For pipelined passes, this is not a big deal because that memory gets recycled every time the pass is invoked on another program unit. For IP passes, it is more important to free memory when it is unused.
Optionally implement this function to release pass memory when it is no longer used.
Reimplemented from llvm::Pass.

Unlink the function from this module, returning it.
Because this removes the function from the module, the call graph node is destroyed. This is only valid if the function does not call any other functions (ie, there are no edges in it's CGN). The easiest way to do this is to dropAllReferences before calling this.
