Jiong Wang 2aff25ba76 [AArch64] Remove duplicated code when handling some GOT relocations types
There are quite a few duplicated code supporting several GP based
relocation types.  They are:

  BFD_RELOC_AARCH64_LD64_GOTOFF_LO15
  BFD_RELOC_AARCH64_MOVW_GOTOFF_G0_NC
  BFD_RELOC_AARCH64_MOVW_GOTOFF_G1

These relocation types are supposed to be used for large memory model PIC/pic
mode under which we will have an initialized GP register points to the base of
GOT table, then these relocations are supposed to put the distance between GOT
entry and GOT table base address into the related instructions.

So, the parameters required to calculate the relocation should be the same as
BFD_RELOC_AARCH64_LD64_GOTPAGE_LO15 etc, all of them are require the GOT entry
address and GOT table base address to perform the relocation.

This patch has removed those duplicated code when handling above listed
relocation types,  grouped them with others as relocation types that are
require GOT table base address during performing relocation, reused the
existed GOT handling code.

The relocation calculation for these types before and after this patch should be
identical.

bfd/
	* elfnn-aarch64.c (aarch64_relocation_aginst_gp_p): New function.
	(elfNN_aarch64_final_link_relocate): Delete duplicated code for
	BFD_RELOC_AARCH64_LD64_GOTOFF_LO15, BFD_RELOC_AARCH64_MOVW_GOTOFF_G0_NC,
	BFD_RELOC_AARCH64_MOVW_GOTOFF_G1.
	* elfxx-aarch64.c (_bfd_aarch64_elf_resolve_relocation): Optimize the
	support for them.

		   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.
