	call branches.  Correct undefined weak destination.

	.sfpr, and correct case where either only savef* or restf* is
	needed.

	Long branch stubs, multiple stub sections.
	* elf64-ppc.h (ppc64_elf_setup_section_lists): Declare.
	(ppc64_elf_next_input_section): Declare.
	* elf64-ppc.c: Move linker-only prototypes.

	(struct ppc_branch_hash_entry): New.
	(struct ppc_link_hash_entry): Add stub_cache, oh.
	(struct ppc_link_hash_table): Add stub_hash_table etc.  Remove
	sstub.  Add sbrlt, srelbrlt, has_14bit_branch, stub_iteration.
	Rename plt_overflow to stub_error.
	(ppc_stub_hash_lookup): Define.
	(ppc_branch_hash_lookup): Define.
	(stub_hash_newfunc): New function.
	(branch_hash_newfunc): New function.

	(ppc_stub_name): New function.
	(ppc_get_stub_entry): New function.
	(ppc_add_stub): New function.
	(create_linkage_sections): Use bfd_make_section_anyway.  Create
	.branch_lt and .rela.branch_lt sections.  Don't create .stub.
	(ppc64_elf_check_relocs): Set has_14bit_branch on R_PPC64_REL14*,
	and set up for plt call stubs.  Link func and func desc syms.
	(ppc64_elf_gc_sweep_hook): Handle REL14* as per REL24.
	(func_desc_adjust): Avoid hash lookup when func desc sym available
	via shortcut, and set links when processing.
	(ppc64_elf_hide_symbol): Likewise.
	(allocate_dynrelocs): Don't allocate stub section here.
	(ppc64_elf_size_dynamic_sections): Handle sbrlt and srelbrlt.
	Remove sstub code.

	(ppc64_elf_size_stubs): Rewrite.
	(ppc64_elf_build_stubs): Rewrite.
	(ppc64_elf_relocate_section): Look up stub entry for REL24
	relocs.  Don't propagate REL14* to dynamic objects.  Look for long
	branch stubs if REL14* or REL24 relocs won't reach.
	(bfd_elf64_bfd_link_hash_table_free): 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.
