Hi , I am an undergraduate student at IIT Bombay working on the control flow of GCC while compiling c code.I am intrested in tracing the path of gcc during compilation.I don't see any good material on this topic anywhere. One approach is to put break points in all of (176) c files in gcc directory and check the flow but that seems to be very time consuming . In response to my previous mail, Lars Segerlund <lars.segerlund@xxxxxxxxx> suggested me of stack trace , but I am not able to do so in a right way.So I am not getting the complete trace.Is there any way out to get the complete stack trace??? --Hari
