Alan Modra b9e5796b0d ELFv2 stub, plt and glink changes
An ELFv2 PLT entry is simply the address of the target function rather
than three (or two) words to specify entry, toc and static chain.  PLT
call stubs are correspondingly simpler and need no thread safety
barrier.  The glink resolver stub and branch table also is simplified,
a change that could be applied to ELFv1 too, but isn't as yet.

	* elf64-ppc.c (PLT_ENTRY_SIZE, PLT_INITIAL_ENTRY_SIZE): Add htab
	parameter and adjust for ELFv2.  Update all uses.
	(PLT_CALL_STUB_SIZE): Delete.
	(ppc64_elf_get_synthetic_symtab): Support new glink layout.
	(allocate_dynrelocs): Likewise.
	(plt_stub_size, build_plt_stub): Adjust for ELFv2.
	(get_r2off): Return 0 for ELFv2 -R.
	(ppc_build_one_stub, ppc_size_one_stub): Adjust for ELFv2.
	(ppc64_elf_size_stubs): Likewise.
	(ppc64_elf_build_stubs): Add new ELFv2 glink.

		   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.
