Max Filippov 0d0bf81a67 gdb: xtensa: fix test for privileged register number
There are no a0-a15 pseudoregisters at the top of the register set in
call0 registers layout. All registers above gdbarch_num_regs (gdbarch)
are privileged. Treat them as such. This fixes the following gdb
assertion seen when 'finish' command is invoked:

  regcache.c:649: internal-error: register_status
  regcache_raw_read(regcache*, int, gdb_byte*):
  Assertion `regnum >= 0 && regnum < regcache->descr->nr_raw_registers'
  failed.

	* xtensa-tdep.c (xtensa_pseudo_register_read): Treat all
	registers above gdbarch_num_regs (gdbarch) as privileged in
	call0 ABI.

		   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.
