Thiago Jung Bauermann 6e4a39ac3c GDB, gdbserver: aarch64-linux: Initial Guarded Control Stack support
Add the org.gnu.gdb.aarch64.gcs feature with the GCSPR register, and the
org.gnu.gdb.aarch64.gcs.linux feature with "registers" to represent the
Linux kernel ptrace and prctl knobs that enable and lock specific GCS
functionality.

This code supports GCS only in Linux userspace applications, so the
GCSPR that is exposed is the one at EL0.

Also, support for calling inferior functions is enabled by adding an
implementation for the shadow_stack_push gdbarch method.

Testcases gdb.arch/aarch64-gcs.exp and gdb.arch/aarch64-gcs-core.exp are
included to cover the added functionality.

The change in the core_find procedure allows aarch64-gcs-core.exp to
recover the output from the crashed program.  It's needed because the
test program in this testcase prints to stdout the value of the GCSPR
right before crashing, and the testcase needs it to check whether GDB
got it right.

		   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

the Free Software Foundation, Inc.  See the file COPYING or

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
