saurabh.jha@arm.com 444c60fe33 gas, aarch64: Add SVE2 lut extension
Introduces instructions for the SVE2 lut extension for AArch64. They are documented in the following links:
* luti2: https://developer.arm.com/documentation/ddi0602/2024-03/SVE-Instructions/LUTI2--Lookup-table-read-with-2-bit-indices-?lang=en
* luti4: https://developer.arm.com/documentation/ddi0602/2024-03/SVE-Instructions/LUTI4--Lookup-table-read-with-4-bit-indices-?lang=en

These instructions use new SVE2 vector operands. They are called
SVE_Zm1_23_INDEX, SVE_Zm2_22_INDEX, and Zm3_12_INDEX and they have
1 bit, 2 bit, and 3 bit indices respectively.

The lsb and width of these new operands are the same as many existing
operands but the convention is to give different names to fields that
serve different purpose so we introduced new fields in aarch64-opc.c
and aarch64-opc.h.

We made a design choice for the second operand of the halfword variant of
luti4 with two register tables. We could have either defined a new operand,
like SVE_Znx2, or we could have use the existing operand SVE_ZnxN. With
the new operand, we would need to implement constraints on register
lists based on either operand or opcode flag. With existing operand, we
could just existing constraint checks using opcode flag. We chose
the second approach and went with SVE_ZnxN and added opcode flag to
enforce lengths of vector register list operands. This way, we can reuse
the existing constraint check logic.

		   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.
