Jan Beulich 1cb0ab18ad x86/Intel: restrict suffix derivation
While in some cases deriving an AT&T-style suffix from an Intel syntax
memory operand size specifier is necessary, in many cases this is not
only pointless, but has led to the introduction of various workarounds:
Excessive use of IgnoreSize and NoRex64 as well as the ToDword and
ToQword attributes. Suppress suffix derivation when we can clearly tell
that the memory operand's size isn't going to be needed to infer the
possible need for the low byte/word opcode bit or an operand size prefix
(0x66 or REX.W).

As a result ToDword and ToQword can be dropped entirely, plus a fair
number of IgnoreSize and NoRex64 can also be got rid of. Note that
IgnoreSize needs to remain on legacy encoded SIMD insns with GPR
operand, to avoid emitting an operand size prefix in 16-bit mode. (Since
16-bit code using SIMD insns isn't well tested, clone an existing
testcase just enough to cover a few insns which are potentially
problematic but are being touched here.)

Note that while folding the VCVT{,T}S{S,D}2SI templates, VCVT{,T}SH2SI
isn't included there. This is to fulfill the request of not allowing L
and Q suffixes there, despite the inconsistency with VCVT{,T}S{S,D}2SI.

		   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.
