Tamar Christina 53b2f36bf6 AArch64: Fix disassembler bug with out-of-order sections
The AArch64 disassembler has an optimization that it uses to reduce the amount
it has to search for mapping symbols during disassembly.  This optimization
assumes that sections are listed in the section header in monotonic increasing
VMAs.  However this is not a requirement for the ELF specification.

Because of this when such "out of order" sections occur the disassembler would
pick the wrong mapping symbol to disassemble the section with.

This fixes it by explicitly passing along the stop offset for the current
disassembly glob and when this changes compared to the previous one we've seen
the optimization won't be performed.  In effect this restarts the search from
a well defined starting point.  Usually the symbol's address.

The existing stop_vma can't be used for this as it is allowed to be unset and
setting this unconditionally would change the semantics of this field.

binutils/ChangeLog:

	* objdump.c (disassemble_bytes): Pass stop_offset.
	* testsuite/binutils-all/aarch64/out-of-order.T: New test.
	* testsuite/binutils-all/aarch64/out-of-order.d: New test.
	* testsuite/binutils-all/aarch64/out-of-order.s: New test.

include/ChangeLog:

	* dis-asm.h (struct disassemble_info): Add stop_offset.

opcodes/ChangeLog:

	* aarch64-dis.c (last_stop_offset): New.
	(print_insn_aarch64): Use stop_offset.

		   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.
