I am using VTune 6.0 and Intel C Compiler 8.0 (MS Visual Studio 6.0, Win XP). Why can't I see all functions in VTune's Call Graph? Many functions are missing, some are shown with TotalTime=0... When I compile program with Microsoft's C compiler all functions are there, everything always works fine. I have set all Visual Studio Project/Settings like the VTune User's Manual says.
