Alan Modra f21dbd7c80 [GOLD] PowerPC64 inline plt sequences
The fixes gold failures to handle inline PLT sequences properly.
PowerPC gold was always turning these back into direct calls due to
gsym->use_plt_offset() returning false.  This is fixed for dynamic
linking by correcting get_reference_flags, and for static linking by
overriding use_plt_offset() in relocate().  The rest of the patch
revolves around needing to create PLT entries for inline PLT calls
when statically linking (for gcc -mlongcall).  The lplt section
handled that for local symbols, now it does globals too.

	* powerpc.cc (Target_powerpc::plt_off): Return proper section
	for static link.
	(Target_powerpc::symval_for_branch): Make public.
	(Target_powerpc::make_lplt_section): Add Symbol_table* param.
	Adjust all calls.
	(Target_powerpc::make_local_plt_entry): Likewise.
	(Target_powerpc::make_local_plt_entry): New variant for global syms.
	(Powerpc_relobj::do_relocate_sections): Don't write lplt contents.
	(Output_data_plt_powerpc::do_write): Write lplt contents here.
	(Output_data_plt_powerpc::Output_data_plt_powerpc): Save
	symbol table pointer.  Adjust all uses.
	(Output_data_plt_powerpc::add_entry): Add stash parameter.  Don't
	do dynamic reloc handling when no reloc section.  Save symbol
	for local plt entries.
	(Output_data_plt_powerpc::add_local_entry): Save symbol.
	(Output_data_plt_powerpc::Local_plt_ent): New class.
	(Output_data_plt_powerpc::sym_ents_): New vector.
	(Target_powerpc::Scan::get_reference_flags): Return
	FUNCTION_CALL|RELATIVE_REF for inline plt relocs.
	(Target_powerpc::Scan::global): Make entries in lplt for inline
	plt call relocation symbols.
	(Target_powerpc::Relocate::relocate): Rename has_plt_offset to
	use_plt_offset.  Set use_plt_offset for inline plt relocs.

		   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.
