Alan Modra e76790600a PR23652, Use symbols from debug bfd for _bfd_elf_find_function
Sometimes DWARF info for a function is incomplete, and the function
can be retrieved by examining symbols.  However, when separate debug
files are used it may be that the original file is completely
stripped of symbols.  This patch teaches BFD to look at symbols from
the debug file in that case.

The patch also removes arm_elf_find_function, instead implementing
elf_backend_maybe_function_sym.  arm_elf_find_function was written
before the generic _bfd_elf_find_function called maybe_function_sym.
aarch64 copied arm, so that file gets the same treatment.  There is
some chance this will speed up arm and aarch64 lookup of function/line.

	PR 23652
	* dwarf2.c (_bfd_dwarf2_stash_syms): New function.
	(_bfd_dwarf2_find_nearest_line): Use it here, passing syms to
	_bfd_elf_find_function.  Call _bfd_elf_find_function in cases
	where _bfd_elf_find_nearest_line would do so.
	* elf.c (_bfd_elf_find_nearest_line): Omit _bfd_elf_find_function
	for dwarf2.
	* elfxx-mips.c (_bfd_mips_elf_find_nearest_line): Similarly.  Tidy.
	* elf32-arm.c (elf32_arm_maybe_function_sym): New function.
	(elf_backend_maybe_function_sym): Define.
	(arm_elf_find_function, elf32_arm_find_nearest_line): Delete.
	(bfd_elf32_find_nearest_line): Don't define.
	* elfnn-aarch64.c (elfNN_aarch64_maybe_function_sym): New function.
	(elf_backend_maybe_function_sym): Define.
	(aarch64_elf_find_function, elfNN_aarch64_find_nearest_line): Delete.
	(bfd_elfNN_find_nearest_line): Don't define.

README

		   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.
