H.J. Lu bb4d2ac2cc Display symbol version when dumping dynrelocs
Both readelf/objdump know how to get symbol version string for dynamic
symbols.  This patch extracts this functionality into a separate
function and uses it to add symbol version string to versioned symbol
names when dumping dynamic relocations.

bfd/

	PR binutils/16496
	* elf-bfd.h (bfd_elf_get_symbol_version_string): New.
	* elf.c (bfd_elf_get_symbol_version_string): New.  Extracted
	from bfd_elf_print_symbol.
	(bfd_elf_print_symbol): Use it.

binutils/

	PR binutils/16496
	* objdump.c (objdump_print_symname): Call
	bfd_elf_get_symbol_version_string to get ELF symbol version
	string.  Append version string if needed.

	* readelf.c (versioned_symbol_info): New enum.
	(get_symbol_version_string): New.  Extracted from
	process_symbol_table.
	(dump_relocations): Add a new argument to indicate if dynamic
	symbol table is used.  Use get_symbol_version_string to get
	symbol version string for dynamic symbol.  Append version string
	if needed.
	(process_relocs): Updated dump_relocations call.
	(process_symbol_table): Use get_symbol_version_string.

ld/testsuite/

	PR binutils/16496
	* ld-cris/weakref3.d: Add symbol version string to versioned
	symbol names in dynamic relocation.
	* ld-cris/weakref4.d: Likewise.
	* ld-elfvers/vers24.rd: Likewise.

	* ld-elf/pr16496a.c: New file.
	* ld-elf/pr16496a.map: Likewise.
	* ld-elf/pr16496b.c: Likewise.
	* ld-elf/pr16496b.od: Likewise.

	* ld-elf/shared.exp (build_tests): Add libpr16496a.so and
	libpr16496b.so tests.

		   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.
