Hi,

The patch below provides support for DW_TAG_module which is used to
represent FORTRAN modules, and possibly other language constructs, such
as C++ namespaces. The patch basically provides support for a module as
a C++ class with static members and functions.

        * dwarf2read.c (dwarf2_update_pc_bounds): New function
        that updates a die's low and high pc bound. Used to
        remedy possible inconsistencies between ELF and DWARF
        information.
        (dwarf2_get_child_pc_bounds): New function that
        calculates the scope bounds of a die's children.
        (dwarf2_add_member_fn): Added a new argument that holds
        a parent die's tag type. Used to determine whether
        a child die's parent is a module and treat the child
        die as a static.
        (scan_partial_symbol): Support the DW_TAG_module tag.
        (add_partial_symbol): Support the DW_TAG_module tag.
        (process_die): Supports the DW_TAG_module tag by
        treating it as a structure scope.
        (read_file_scope): Moved  and enhanced some of the code
         to create the new dwarf2_get_child_pc_bounds()
        function.
        (read_structure_scope): Now supports the DW_TAG_module
        tag as a class and handles module variables and
        functions/subroutines as static members.
        (new_symbol): Now supports the DW_TAG_module tag and
        adds a module symbol to the global symbol list.
        (read_die_type): Now supports the DW_TAG_module tag
        as a structure scope.
