Ulrich Weigand cd453cd072 PowerPC64 ELFv2 ABI: base support
This is the first patch of a series to implement support for the
PowerPC ELFv2 ABI.  While powerpc64le-linux will use ELFv2, and
the existing powerpc64-linux code will continue to use ELFv1,
in theory ELFv2 is also defined for big-endian systems (and
ELFv1 was also defined for little-endian systems).

Therefore this patch adds a new tdep->elf_abi variable to decide
which ABI version to use.  This is detected from the ELF header
e_flags value; if this is not present, we default to ELFv2 on
little-endian and ELFv1 otherwise.

This patch does not yet introduce any actual difference in GDB's
handling of the two ABIs.  Those will be added by the remainder
of this patch series.

For an overview of the changes in ELFv2, have a look at the
comments in the patch series that added ELFv2 to GCC, starting at:
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01144.html

gdb/ChangeLog:

	* ppc-tdep.h (enum powerpc_elf_abi): New data type.
	(struct gdbarch_tdep): New member elf_abi.

	* rs6000-tdep.c: Include "elf/ppc64.h".
	(rs6000_gdbarch_init): Detect ELF ABI version.

		   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.
