Alan Modra e00e81980c Don't return DW_AT_name for function name in C++
DW_AT_name for functions typically just contains the base function
name, so lacks namespace, class and parameter information.  It would
be possible to extract all these from the DWARF, but at a considerable
complication of the parser in dwarf2.c, and then you'd need to mangle
it all together.  Much simpler is to look up the actual symbol.  This
patch does that, avoiding the extra symbol lookup when the language
doesn't do name mangling.

	PR 17541
	* dwarf2.c (struct comp_unit): Add "lang".
	(non_mangled): New function.
	(struct funcinfo): Add "is_linkage".  Reorder for better packing.
	Make "name" a const char*.
	(lookup_address_in_function_table): Delete functionname_ptr param.
	(find_abstract_instance_name): Add is_linkage param.  Set if we
	have DW_AT_linkage_name or non_mangled DW_AT_name.
	(scan_unit_for_symbols): Similarly set func->is_linkage.
	(parse_comp_unit): Stash DW_AT_language.
	(comp_unit_find_nearest_line): Replace functionname_ptr param
	with function_ptr param.
	(_bfd_dwarf2_find_nearest_line): Adjust above calls.  Set
	functionname_ptr from function->name.  Call _bfd_elf_find_function
	to retrieve symbol for function if not linkage name.
	(_bfd_elf_find_function): Add bfd_target_elf_flavour test, moved from..
	* elf.c (elf_find_function): ..here.
	(_bfd_elf_find_nearest_line): Adjust calls.
	* elf-bfd.h (_bfd_elf_find_function): Declare.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
