Richard Sandiford e950b34539 [AArch64][SVE 27/32] Add SVE integer immediate operands
This patch adds the new SVE integer immediate operands.  There are
three kinds:

- simple signed and unsigned ranges, but with new widths and positions.

- 13-bit logical immediates.  These have the same form as in base AArch64,
  but at a different bit position.

  In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical
  immediate <limm> is not allowed to be a valid DUP immediate, since DUP
  is preferred over DUPM for constants that both instructions can handle.

- a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}".
  In some contexts the operand is signed and in others it's unsigned.
  As an extension, we allow shifted immediates to be written as a single
  integer, e.g. "#256" is equivalent to "#1, LSL #8".  We also use the
  shiftless form as the preferred disassembly, except for the special
  case of "#0, LSL #8" (a redundant encoding of 0).

README

		   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.
