SgNodeHelper::determineFunctionDefinition

This function determines for a given function‐call‐expression its corresponding function‐definition (by using get_definingDeclaration). This function has constant complexity. It does not perform a search, but uses the information as present in the AST. If this information is not sufficient to determine the definition of a function it returns 0. For a consistent AST this will find all definitions in the same file, but not in a other SgFile.

Synopsis

Declared in <src/midend/abstractLayer/SgNodeHelper.h>

SgFunctionDefinition*
determineFunctionDefinition(SgFunctionCallExp* fCall);

Description

For an inter‐procedural analysis a more elaborate mechanism is required to perform a static function call lresolution (also handling function pointers and virtual functions).

Return Value

This class represents the concept of a scope in C++ (e.g. global scope, fuction scope, etc.).

Parameters

Name	Description
fCall	This class represents the concept of a C++ function call (which is an expression).
