Attached.

Ok, DON'T try to apply the dwarf2_physname*-2.patch files. I've 
hand-edited them to keep the "meat" separate from the trivial changes. 
These are also based on yesterday's repo.

If you want to apply the patch, use the one called 
dwarf2_physname-20100128.patch. That's just a blanket diff on my local 
sandbox, updated against CVS HEAD today.

PS. I've had to pull a few patches from expr-cumulative. I have made a 
concerted effort to credit authors with their work, but I may have 
overlooked something. I apologize in advance if I have accidentally 
omitted to credit Tom, Sami, or Jan for any of their work which I pulled 
in for this submission.

*** ChangeLog -- dwarf2_physname-2.patch

2009-11-20  Keith Seitz  <keiths@redhat.com>

	Based on work from Daniel Jacobowitz  <dan@codesourcery.com>
	* c-typeprint.c (cp_type_print_method_args): For non-static methods,
	print out const or volatile qualifiers, too.
	(c_type_print_args): Add parameters show_artificial and language.
	Skip artificial parameters when requested.
	Use the appropriate language printer.
	(c_type_print_varspec): Tell c_type_print_args to skip artificial
	parameters and pass language_c.
	* dwarf2read.c (die_list): New file global.
	(struct partial_die_info): Update comments for name field.
	(pdi_needs_namespace): Renamed to ...
	(die_needs_namespace): ... this. Rewrite.
	(dwarf2_linkage_name): Remove.
	(add_partial_symbol): Do not predicate the call to
	partial_die_full_name based on pdi_needs_namespace.
	Remove call to cp_check_possible_namespace_symbols and associated
	outdated comments.
	(guess_structure_name): Do not inspect child subprogram DIEs.
	(dwarf2_fullname): Update comments.
	Use die_needs_namespace to assist in computing the name.
	(read_func_scope): Use dwarf2_name to get the DIE's name.
	Use dwarf2_physname to get the "linkage name" of the DIE.
	(dwarf2_add_member_field): Use dwarf2_physname instead of
	dwarf2_linkage_name.
	(read_structure_type): For structs and classes, set TYPE_NAME, too.
	(determine_class): Remove.
	(read_partial_die): Ignore DW_AT_MIPS_linkage_name for all languages
	except Ada.
	(new_symbol): Unconditionally call dwarf2_name.
	Compute the "linkage name" using dwarf2_physname.
	Use dwarf2_name instead of dwarf2_full_name for enumerator DIEs.
	When determining to scan for anonymous C++ namespaces, ignore
	the linkage name.
	(physname_prefix): New function.
	(physname_prefix_1): New function.
	(dwarf2_physname): New function.
	(_initialize_dwarf2_read): Initialize die_list.
	* gnu-v3-eabi.c (gnu_v3_find_method_in): Remove unused variable
	physname.
	(gnu_v3_print_method_ptr): Use the physname for virtual methods
	without a demangled name.
	Print out type information for non-virtual methods.
         * linespec.c (decode_line_1): Force ANY string using "::" (or
	"." for java) to use decode_compound, and clean up any stray quoting.
         If we found a file symtab, re-evaluate whether the remainder 
is_quoted.
         (decode_compound): Stop consuming at an open parenthesis.
         Keep template parameters.
         Keep any overload information.
         Keep keywords like "const".
         Remove paren_pointer.
         Move is_quoted check from set_flags to here.
         Remove #if 0 code from 2000. Ten years is long enough.
         (find_method): Before comparing symbol names, canonicalize the 
string
         from the user.
         If a specific overload is requested, find it. Otherwise throw 
an error.
	(find_method_overload_end): New function.
	(set_flags): Remove.
         (decode_compound): Assume that parentheses are matched.
         It's a lot easier.
	* symtab.c (symbol_find_demangled_name): Add DMGL_VERBOSE flag
	to cplus_demangle.
	* linespec.c (decode_line_1): Keep important keywords like
	"const" and "volatile".
	* symtab.h (SYMBOL_CPLUS_DEMANGLED_NAME): Remove.
	* typeprint.h (c_type_print_args): Add declaration.
	* ui-file.c (do_ui_file_obsavestring): New function.
	(ui_file_obsavestring): New function.
	* ui-file.h (ui_file_obsavestring): Add declaration.
	* valops.c (find_overload_match): Resolve the object to
	a non-pointer type.
	If the object is a data member, search the object for the member
	and return with staticp set.
	Use SYMBOL_NATURAL_NAME instead of SYMBOL_CPLUS_DEMANGLED_NAME.
	Do not attempt to extract a function name from non-function types.
	If the extracted function name and the original name are the same,
	we don't have a C++ method.

	From Jan Kratochvil  <jan.kratochvil@redhat.com>:
     	* dwarf2read.c (new_symbol <DW_TAG_enumerator>): Call 
dwarf2_full_name.
