Alan Modra 61a457e5da e200 LSP support
It has bothered me for a long time that we have disabled LSP (and SPE)
tests.  Also the LSP test comment indicating there is something wrong
with get_powerpc_dialect.  I don't think there is.  Decoding of a VLE
instruction depends on whether the processor is in VLE mode (some
processors support both VLE and standard PPC) which we flag per
section with SHF_PPC_VLE for decoding when disassembling.

Background: Some versions of powerpc e200 have "Lightweight Signal
Processing" support, examples being e200z215 and e200z425.  As far as
I can tell, LSP and SPE are mutually exclusive.  This seems to be
borne out by insn encoding, for example LSP "zvaddih" and SPE "evaddw"
have the same encoding.  So none of the processor descriptions in
ppc_opts ought to have both PPC_OPCODE_LSP and PPC_OPCODE_SPE/2, if we
want disassembly to work.  I also could not find anything to suggest
that the LSP insns are enabled only in VLE mode, which means the LSP
insns should not be in vle_opcodes.

Fix all this by moving the LSP insns to their own table, and add a new
e200z2 cpu entry with LSP support, removing LSP from -me200z4 and from
-mvle.  (Yes, I know, as I said above some of the e200z4 processors
have LSP.  Others have SPE.  It's hard to choose good options.  Think
of z2 as meaning earlier, z4 as later.)  Also add -mlsp to allow
adding the LSP insn set.

		   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.
