Pedro Alves 8322445e05 Introduce interpreter factories
If every UI instance has its own set of interpreters, then the current
scheme of creating the interpreters at GDB initialization time no
longer works.  We need to create them whenever a new UI instance is
created.

The scheme implemented here has each interpreter register a factory
callback that when called creates a new instance of a specific
interpreter type.  Then, when some code in gdb looks up an interpreter
(always by name), if there's none yet, the factory method is called to
construct one.

	(struct cli_interp): ... this new structure.

	(cli_on_no_history): Use interp_ui_out.

	(cli_interpreter_init): Return the interp's data instead of NULL.
	(cli_interpreter_resume, cli_interpreter_exec, cli_ui_out): Adjust
	to cli_uiout being in the interpreter's data.
	(cli_interp_procs): New, factored out from _initialize_cli_interp.
	(cli_interp_factory): New function.
	(_initialize_cli_interp): Call interp_factory_register.
	* interps.c (get_interp_info): New, factored out from ...
	(get_current_interp_info): ... this.
	(interp_new): Add parameter 'data'.  Store it.
	(struct interp_factory): New function.
	(interp_factory_p): New typedef.  Define a VEC_P.
	(interpreter_factories): New global.
	(interp_factory_register): New function.
	(interp_add): Add 'ui' parameter.  Use get_interp_info and
	interp_lookup_existing.
	(interp_lookup): Rename to ...
	(interp_lookup_existing): ... this.  Add 'ui' parameter.  Don't
	check for NULL or empty name here.
	(interp_lookup): Add 'ui' parameter and reimplement.
	(interp_set_temp, interpreter_exec_cmd): Adjust.
	(interpreter_completer): Complete on registered interpreter
	factories instead of interpreters.
	* interps.h (interp_factory_func): New typedef.
	(interp_factory_register): Declare.
	(interp_new, interp_add): Adjust.
	(interp_lookup): Declare.
	* main.c (captured_main): Adjust.
	* mi/mi-interp.c (mi_cmd_interpreter_exec): Adjust.
	(mi_interp_procs): New, factored out from
	_initialize_mi_interp.
	(mi_interp_factory): New function.
	* python/python.c (execute_gdb_command): Adjust.
	* tui/tui-interp.c (tui_init): If top level, set the tui_interp
	global.
	(tui_interp_procs): New.
	(tui_interp_factory): New function.
	(_initialize_tui_interp): Call interp_factory_register.

		   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.
