Alan Modra 91a65d2fe8 [GOLD] Relocate::relocate() params
Some linker code editing needs to change multiple insns.  In some
cases multiple relocations are involved and it is not sufficient to
make the changes independently as relocations are processed, because
doing so might lead to a partial edit.  So in order to safely edit we
need all the relocations available in relocate().  Also, to emit
edited relocs corresponding to the edited code sequence we need some
way to pass information from relocate() to relocate_relocs(),
particularly if the edit depends on insns.  We can't modify input
relocs in relocate() as they are mmapped PROT_READ, nor it is
particularly clean to write relocs to the output at that stage.  So
add a Relocatable_relocs* field to relinfo to mark edited relocs.

Given that relocate is passed the raw reloc pointer, it makes sense to
remove the rel/rela parameter and r_type too.  However, that means the
mips relocate() needs to know whether SHT_REL or SHT_RELA relocs are
being processed.  So add a rel_type for mips, which also has the
benefit of removing relocate() overloading there.

This patch adds the infrastructure without making use of it.

Note that relinfo->rr will be NULL if not outputting relocations.

	* object.h (struct Relocate_info): Add "rr".
	* reloc.h (Relocatable_relocs::set_strategy): New accessor.
	* reloc.cc (Sized_relobj_file::do_relocate_sections): Init
	relinfo.rr for relocate_section and relocate_relocs.
	* powerpc.cc (relocate): Add rel_type and preloc parameters.
	Delete rela and r_type params, instead recalculate these from
	preloc.
	(relocate_relocs): Delete Relocatable_relocs* param, instead
	use relinfo->rr.
	* aarch64.cc: Likewise.
	* arm.cc: Likewise.
	* i386.cc: Likewise.
	* mips.cc: Likewise.
	* s390.cc: Likewise.
	* sparc.cc: Likewise.
	* target.h: Likewise.
	* tilegx.cc: Likewise.
	* x86_64.cc: Likewise.
	* testsuite/testfile.cc: Likewise.
	* target-reloc.h (relocate_section): Adjust to suit.
	(apply_relocation, relocate_relocs): Likewise.

		   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.
