Alan Modra a3e60ddb0b Retry powerpc gold stub grouping when groups prove too large
An unusually large number of stubs can result in the default section
group size being too large;  sections plus stubs exceed the range of a
branch.  Restarting the relaxation pass with a smaller group size can
sometimes help.

	* powerpc.cc (struct Stub_table_owner): New.
	(Powerpc_relobj): Rename stub_table_ to stub_table_index_, an
	unsigned int vector.  Update all references.
	(powerpc_relobj::set_stub_table): Take an unsigned int param
	rather than a Stub_table.  Update callers.
	(Powerpc_relobj::clear_stub_table): New function.
	(Target_powerpc): Add relax_failed_, relax_fail_count_ and
	stub_group_size_ vars.
	(Target_powerpc::new_stub_table): Delete.
	(max_branch_delta): New function, extracted from..
	(Target_powerpc::Relocate::relocate): ..here..
	(Target_powerpc::Branch_info::make_stub): ..and here.  Return
	status on whether stub created successfully.
	(Stub_control::Stub_control): Add "no_size_errors" param.  Move
	default sizing to..
	(Target_powerpc::do_relax): ..here.  Init stub_group_size_ and
	reduce on relax failure.
	(Target_powerpc::group_sections): Add "no_size_errors" param.
	Use stub_group_size_.  Set up group info in a temp vector,
	before building Stub_table vector.  Account for input sections
	possibly already converted to relaxed sections.
	(Stub_table::init): Delete.  Merge into..
	(Stub_table::Stub_table): ..here.
	(Stub_table::can_reach_stub): New function.
	(Stub_table::add_plt_call_entry): Add "from" parameter and
	return true iff stub could be reached.
	(Stub_table::add_long_branch_entry): Similarly.  Add "r_type"
	param too.
	(Stub_table::clear_stubs): Add "all" param.

		   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.
