Indu Bhagat 41eed6e187 sframe.h: add support for .cfi_b_key_frame
ARM 8.3 provides five separate keys that can be used to authenticate
pointers. There are two key for executable (instruction) pointers. The
enum pointer_auth_key in gas/config/tc-aarch64.h currently holds two keys:
  enum pointer_auth_key {
    AARCH64_PAUTH_KEY_A,
    AARCH64_PAUTH_KEY_B
  };

Analogous to the above, in SFrame format V1, a bit is reserved in the SFrame
FDE to indicate which key is used for signing the frame's return addresses:
  - SFRAME_AARCH64_PAUTH_KEY_A has a value of 0
  - SFRAME_AARCH64_PAUTH_KEY_B has a value of 1

Note that the information in this bit will always be used along with the
mangled_ra_p bit, the latter indicates whether the return addresses are
mangled/contain PAC auth bits.

include/ChangeLog:

	* sframe.h (SFRAME_AARCH64_PAUTH_KEY_A): New definition.
	(SFRAME_AARCH64_PAUTH_KEY_B): Likewise.
	(SFRAME_V1_FUNC_INFO): Adjust to accommodate pauth_key.
	(SFRAME_V1_FUNC_PAUTH_KEY): New macro.
	(SFRAME_V1_FUNC_INFO_UPDATE_PAUTH_KEY): 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.
