Max Filippov 4b8e28c793 xtensa: use property tables for correct disassembly
xtensa disassembler does not use information from the .xt.prop sections
to switch between code/data disassembly in text sections. This may
result in incorrect disassembly when data is interpreted as code and
disassembler loses synchronization with instruction stream. Use .xt.prop
section information to correctly interpret code and data and synchronize
with instruction stream.

bfd/
	* elf32-xtensa.c (xtensa_read_table_entries): Make global.
	(compute_fill_extra_space): Drop declaration. Rename function to
	xtensa_compute_fill_extra_space.
	(compute_ebb_actions, remove_dead_literal): Update references to
	compute_fill_extra_space.

include/
	* elf/xtensa.h (xtensa_read_table_entries)
	(xtensa_compute_fill_extra_space): New declarations.

opcodes/
	* xtensa-dis.c (bfd.h, elf/xtensa.h): New includes.
	(dis_private): Add new fields for property section tracking.
	(xtensa_coalesce_insn_tables, xtensa_find_table_entry)
	(xtensa_instruction_fits): New functions.
	(fetch_data): Bump minimal fetch size to 4.
	(print_insn_xtensa): Make struct dis_private static.
	Load and prepare property table on section change.
	Don't disassemble literals. Don't disassemble instructions that
	cross property table boundaries.

		   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.
