Andrew Burgess c005eb9e34 ld: Extend options for altering orphan handling behaviour.
Replace the options --warn-orphan and --no-warn-orphan with a single
option --orphan-handling=MODE, where mode can be place, warn, error, and
discard.

Mode 'place' is the default, and is the current behaviour, placing the
orphan section into a suitable output section.

Mode 'warn' is the same as '--warn-orphan'.  The orphan is also placed
using the same algorithm as for 'place'.

Mode 'error' is the same as '--warn-orphan' and '--fatal-warnings'.

Mode 'discard' assigns all output sections to the /DISCARD/ section.

ld/ChangeLog:

	* ld.h (enum orphan_handling_enum): New.
	(ld_config_type): Remove warn_orphan, add orphan_handling.
	* ldemul.c (ldemul_place_orphan): Remove warning about orphan
	sections.
	* ldlang.c (ldlang_place_orphan): New function.
	(lang_place_orphans): Call ldlang_place_orphan.
	* ldlex.h (enum option_values): Remove OPTION_WARN_ORPHAN and
	OPTION_NO_WARN_ORPHAN, add OPTION_ORPHAN_HANDLING.
	* lexsup.c (ld_options): Remove 'warn-orphan' and
	'no-warn-orphan', add 'orphan-handling'.
	(parse_args): Remove handling for OPTION_WARN_ORPHAN and
	OPTION_NO_WARN_ORPHAN, add handling for OPTION_ORPHAN_HANDLING.
	* NEWS: Replace text about --warn-orphan with --orphan-handling.
	* ld.texinfo (Options): Remove --warn-orphan entry and add
	entry on --orphan-handling.
	(Orphan Sections): Add reference to relevant command line options.

ld/testsuite/ChangeLog:

	* ld-elf/elf.exp: Switch to rely on run_dump_test.
	* ld-elf/orphan-5.l: Update expected output.
	* ld-elf/orphan-5.d: New file.
	* ld-elf/orphan-6.d: New file.
	* ld-elf/orphan-6.l: New file.
	* ld-elf/orphan-7.d: New file.
	* ld-elf/orphan-7.map: New file.
	* ld-elf/orphan-8.d: New file.

		   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.
