Alan Modra d3e454b956 PowerPC non-PIC to PIC editing for protected var access
This is a linker-only solution to the incompatibility between shared
library protected visibility variables and using .dynbss and copy
relocs for non-PIC access to shared library variables.

bfd/
	* elf32-ppc.c (struct ppc_elf_link_hash_entry): Add has_addr16_ha
	and has_addr16_lo.  Make has_sda_refs a bitfield.
	(ppc_elf_check_relocs): Set new flags.
	(ppc_elf_link_hash_table_create): Update default_params.
	(ppc_elf_adjust_dynamic_symbol): Clear protected_def in cases
	where we won't be making .dynbss entries or editing code.  Set
	params->pic_fixup when we'll edit code for protected var access.
	(allocate_dynrelocs): Allocate got entry for edited code and
	discard dyn_relocs.
	(struct ppc_elf_relax_info): Add picfixup_size.
	(ppc_elf_relax_section): Rename struct one_fixup to struct
	one_branch_fixup.  Rename fixups to branch_fixups.  Size space for
	pic fixups.
	(ppc_elf_relocate_section): Edit non-PIC accessing protected
	visibility variables to PIC.  Don't emit dyn_relocs for code
	we've edited.
	* elf32-ppc.h (struct ppc_elf_params): Add pic_fixup.
ld/
	* emultempl/ppc32elf.em: Handle --no-pic-fixup.
	(params): Init new field.
	(ppc_before_allocation): Enable relaxation for pic_fixup.

		   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.
