Displaying Fortran Module Data

Totalview® User Guide : Part II: Debugging Tools and Tasks : Examining and Editing Data and Program Elements : Displaying Fortran Types : Displaying Fortran Module Data

TotalView tries to locate all data associated with a Fortran module and display it all at once. For functions and subroutines defined in a module, TotalView adds the full module data definition to the list of modules displayed in the Stack Frame Pane.

TotalView only displays a module if it contains data. Also, the amount of information that your compiler gives TotalView can restrict what is displayed.

Although a function may use a module, TotalView doesn’t always know if the module was used or what the true names of the variables in the module are. If this happens, either of the following occurs:

Module variables appear as local variables of the subroutine.

A module appears on the list of modules in the Stack Frame Pane that contains (with renaming) only the variables used by the subroutine.


CLI: dprint variable-name

Alternatively, you can view a list of all the known modules by using the Tools > Fortran Modules command. Because Fortran modules display in a Variable Window, you can dive on an entry to display the actual module data, as shown in Figure 144.

If you are using the SUNPro compiler, TotalView can only display module data if you force TotalView to read the debug information for a file that contains the module definition or a module function. For more information, see “Finding the Source Code for Functions”.
