Will Schmidt c8a379440e [PATCH] gdb-power10-single-step
Hi,
  This is based on a patch originally written by Alan Modra.
Powerpc / Power10 ISA 3.1 adds prefixed instructions, which
are 8 bytes in length.  This is in contrast to powerpc previously
always having 4 byte instruction length.  This patch implements
changes to allow GDB to better detect prefixed instructions, and
handle single stepping across the 8 byte instructions.

Added #defines to help test for PNOP and prefix instructions.
Update ppc_displaced_step_copy_insn() to handle pnop and prefixed
instructions whem R=0 (non-pc-relative).

Updated ppc_displaced_step_fixup() to properly handle the offset
value matching the current instruction size

Updated the for-loop within ppc_deal_with_atomic_sequence() to
count instructions properly in case we have a mix of 4-byte and
8-byte instructions within the atomic_sequence_length.

Added testcase and harness to exercise pc-relative load/store
instructions with R=0.

        gdb/ChangeLog:
        * rs6000-tdep.c:  Add support for single-stepping of
        prefixed instructions.

        gdb/testsuite/ChangeLog:
        * gdb.arch/powerpc-plxv-nonrel.s:  Testcase using
        non-relative plxv instructions.
        * gdb.arch/powerpc-plxv-nonrel.exp: Testcase harness.

		   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.
