Jan Beulich a50187b2c6 x86: harmonize disp with imm handling
Certain disp values may trigger "... shortened to ..." warnings when
equivalent imm ones don't. In some of the cases there are also
differences (for non-64-bit code) between BFD64 and !BFD64 builds. The
resulting encodings (i.e. use [or not] of the shorter disp8 / imm8
forms) are also different in some cases. Make this handling consistent.

Note that using equivalent 16-bit mode displacements / immediates
continues to expose entirely different behavior (see the disp-imm-16
testcase added by an earlier patch). This may want to be the subject of
further changes, but it'll then quickly become obvious that e.g. keying
use of extend_to_32bit_address() to non-64-bit mode isn't appropriate
either: Once we allow wrapping operands, we would better do so
consistently, in which case all of this would need to become dependent
upon address or operand size instead of mode.

		   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.
