[cfe-dev] Problem with visiting AST to find STL function call

[HotDog]

I’m writing a small program with clang library to find function call in any C++ code.
It’s work well on user defined function.
But it’s not work if C++ code call the built-in STL function.

This is an example C++ code
I want to visit for_each() function call
--------------------------------------
#include <vector>
#include <algorithm>

int main() {
    vector<int> my_vector;
    for_each(my_vector.begin(), my_vector.end(), ...);
    return 0;
}
--------------------------------------

This is my clang’s AST consumer class
--------------------------------------
class MyASTConsumer :
    public ASTConsumer,
    public RecursiveASTVisitor<MyASTConsumer> {
    
    void HandleTranslationUnit(ASTContext &Ctx) {
        TraverseDecl(Ctx.getTranslationUnitDecl());
    }

    bool VisitCallExpr(CallExpr *E) {
        E->dump(); // just print this function call to screen
        return true;
    }
}
--------------------------------------

I’ve checked my program that
- User defined function call is work well.
- Standard C function call is work well. (such as printf(), time(), abs(), ...)
- STL function call is NOT work.
- My clang have successfully detected the included STL header. (I’ve checked by printing function declaration such as for_each(), find_if(), swap(), ...)

My clang environment are
- Clang library 3.1 complied with MSVC 2010.
- My program is written on MSVC 2010. (STL header is MSVC 2010)
- My computer is Windows 7 x64

Thank you for any suggestions.
