Siddhesh Poyarekar 7e05773767 [PATCH v3] aarch64: Emit jump slot for conditional branch to undefined symbols
The linker silently writes out a conditional branch to 0 if the
target symbol in R_AARCH64_CONDBR19 or R_AARCH64_TSTBR14 relocations is
undefined.  Emit a PLT instead so that behaviour is the same for these
relocations as the llvm linker.

The special behaviour for undefined weak symbols, where conditional
branches to such symbols result in a branch unto themselves, has been
retained.  This is because the weak-undefined.s test explicitly checks
for that, leading me to conclude that it's expected behaviour.

bfd	* elfnn-aarch64.c (elfNN_aarch64_final_link_relocate): Club
	BFD_RELOC_AARCH64_BRANCH19 and BFD_RELOC_AARCH64_TSTBR14
	cases with BFD_RELOC_AARCH64_JUMP26.
	(elfNN_aarch64_check_relocs): Likewise.

ld	* testsuite/ld-aarch64/aarch64-elf.exp: New test
	emit-relocs-560.
	* testsuite/ld-aarch64/emit-relocs-560.d: New file.
	* testsuite/ld-aarch64/emit-relocs-560.s: New file.

		   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.
