Simon Marchi 2b16913cdc gdb: make gdbarch_alloc take ownership of the tdep
It's currently not clear how the ownership of gdbarch_tdep objects
works.  In fact, nothing ever takes ownership of it.  This is mostly
fine because we never free gdbarch objects, and thus we never free
gdbarch_tdep objects.  There is an exception to that however: when
initialization fails, we do free the gdbarch object that is not going to
be used, and we free the tdep too.  Currently, i386 and s390 do it.

To make things clearer, change gdbarch_alloc so that it takes ownership
of the tdep.  The tdep is thus automatically freed if the gdbarch is
freed.

Change all gdbarch initialization functions to pass a new gdbarch_tdep
object to gdbarch_alloc and then retrieve a non-owning reference from
the gdbarch object.

Before this patch, the xtensa architecture had a single global instance
of xtensa_gdbarch_tdep.  Since we need to pass a dynamically allocated
gdbarch_tdep_base instance to gdbarch_alloc, remove this global
instance, and dynamically allocate one as needed, like we do for all
other architectures.  Make the `rmap` array externally visible and
rename it to the less collision-prone `xtensa_rmap` name.

		   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.
