Gustavo Romero 681ad8174d gdb: aarch64: Remove MTE address checking from memtag_matches_p
This commit removes aarch64_linux_tagged_address_p from
aarch64_linux_memtag_matches_p. aarch64_linux_tagged_address_p checks if
an address is tagged (MTE) or not.

The check is redundant because aarch64_linux_memtag_matches_p is always
called from the upper layers (i.e. from printcmd.c via gdbarch hook
gdbarch_memtag_matches_p) after either gdbarch_tagged_address_p (that
already points to aarch64_linux_tagged_address_p) has been called or
after should_validate_memtags (that calls gdbarch_tagged_address_p at
the end) has been called, so the address is already checked. Hence:

a) in print_command_1, gdbarch_memtag_matches_p is called only after
should_validate_memtags is called, which checks the address at its end;

b) in memory_tag_check_command, gdbarch_memtag_matches_p is called only
after gdbarch_tagged_address_p is called directly.

Also, because after this change the address checking only happens at the
upper layer it now allows the address checking to be specialized easily
per target, via a target hook.

		   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.
