Antoine Tremblay 1eb7c2d886 Map registers to remote numbers when encoding an ax_reg or ax_reg_mask operation
When encoding the agent expression operation ax_reg or ax_reg_mask, the
register number used is internal to GDB. However GDBServer expects a tdesc
based number.

This usually does not cause a problem since at the moment, for raw
registers GDBServer R trace action ignores the register mask and just
collects all registers.

It can be a problem, however with pseudo registers on some platforms if the
tdesc number doesn't match the GDB internal register number.

This is the case with ARM, the upcoming ARM tracepoint support, fails
these test cases without this patch:

gdb.trace/collection.exp: collect register locals collectively:*

GDBSever would exit with: unhandled register size
Since the register number is not mapped.

This patch fixes these issues by calling gdbarch_remote_register_number
before encoding the register number in the ax_reg or ax_reg_mask operation.

Tested on x86 native-gdbserver no regressions observed.

gdb/ChangeLog:

	* ax-general.c (ax_reg): Call gdbarch_remote_register_number.
	(ax_reg_mask): Likewise.

		   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.
