Alan Modra 53291d1f16 powerpc relax_section and section contents cache
This patch provides a means for backend relax_section support to
increase the size of a section without needing to reallocate
section contents.  This helps reduce memory usage when the added space
does not need to be written in relax_section, as is the case for
powerpc.  Writing the stubs later means a few tweaks are needed in the
powerpc relocate_section function, but also removes some code
duplication since the extra ld -r relocs can be written there too.

	* elf-bfd.h (struct elf_backend_data): Add caches_rawsize.
	* elfxx-target.h (elf_backend_caches_rawsize): Define.
	(elfNN_bed): Init new field.
	* elflink.c (elf_link_input_bfd): Handle caches_rawsize.
	* elf32-ppc.c (shared_stub_entry): Zero addi offset.
	(ppc_elf_relax_section): Don't reallocate section here, write
	stubs, or write out relocs for ld -r here..
	(ppc_elf_relocate_section): ..instead write stubs here, and use
	existing code to write out relocs for ld -r.  Fix offset
	adjustment on reloc for little-endian.
	(elf_backend_caches_rawsize): Define.

		   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.
