Member Function Documentation

internalizeModule()

bool InternalizePass::internalizeModule	(	Module &	TheModule,
		CallGraph *	CG = nullptr
	)

Run the internalizer on TheModule, returns true if any changes was made.

If the CallGraph CG is supplied, it will be updated when internalizing a function (by removing any edge from the "external node")
