Alan Modra 73d5efd7e1 ARM cmse_scan segfault
This code in elf_link_add_object_symbols:

      ret = elf_add_dt_needed_tag (abfd, info, soname, add_needed);
      if (ret < 0)
	goto error_return;

      /* If we have already included this dynamic object in the
	 link, just ignore it.  There is no reason to include a
	 particular dynamic object more than once.  */
      if (ret > 0)
	return TRUE;

prevents a shared library from being loaded twice by ensuring that any
library soname doesn't match the soname of one already loaded.  This
happens before sym_hashes are allocated, which leaves sym_hashes NULL.

cmse_scan looks at library symbols, and when attempting to look up a
global symbol will segfault if sym_hashes is zero.

	* elf32-arm.c (elf32_arm_size_stubs): Exclude dynamic library
	BFDs that have not been loaded.

		   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.
