Alan Modra c3f72de4f5 PowerPC disassembly of pcrel references
This adds some annotation to Power10 pcrel instructions, displaying
the target address (ie. pc + D34 field) plus a symbol if there is one
at exactly that target address.  pld from the .got or .plt will also
look up the entry and display it, symbolically if there is a dynamic
relocation on the entry.

include/
	* dis-asm.h (struct disassemble_info): Add dynrelbuf and dynrelcount.
binutils/
	* objdump.c (struct objdump_disasm_info): Delete dynrelbuf and
	dynrelcount.
	(find_symbol_for_address): Adjust for dynrelbuf and dynrelcount move.
	(disassemble_section, disassemble_data): Likewise.
opcodes/
	* ppc-dis.c (struct dis_private): Add "special".
	(POWERPC_DIALECT): Delete.  Replace uses with..
	(private_data): ..this.  New inline function.
	(disassemble_init_powerpc): Init "special" names.
	(skip_optional_operands): Add is_pcrel arg, set when detecting R
	field of prefix instructions.
	(bsearch_reloc, print_got_plt): New functions.
	(print_insn_powerpc): For pcrel instructions, print target address
	and symbol if known, and decode plt and got loads too.

		   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.
