Andrew Burgess b20885b0a4 gdb: add a custom command completer for disassemble command
Add a new command completer function for the disassemble command.
There are two things that this completion function changes.  First,
after the previous commit, the new function calls skip_over_slash_fmt,
which means that hitting tab after entering a /OPT flag now inserts a
space ready to start typing the address to disassemble at:

  (gdb) disassemble /r<TAB>
  (gdb) disassemble /r <CURSOR>

But also, we now get symbol completion after a /OPT option set,
previously this would do nothing:

  (gdb) disassemble /r mai<TAB>

But now:

  (gdb) disassemble /r mai<TAB>
  (gdb) disassemble /r main <CURSOR>

Which was my main motivation for working on this commit.

However, I have made a second change in the completion function.
Currently, the disassemble command calls the generic
location_completer function, however, the disassemble docs say:

     Note that the 'disassemble' command's address arguments are specified
  using expressions in your programming language (*note Expressions:
  Expressions.), not location specs (*note Location Specifications::).
  So, for example, if you want to disassemble function 'bar' in file
  'foo.c', you must type 'disassemble 'foo.c'::bar' and not 'disassemble
  foo.c:bar'.

And indeed, if I try:

  (gdb) disassemble hello.c:main
  No symbol "hello" in current context.
  (gdb) disassemble hello.c::main
  No symbol "hello" in current context.
  (gdb) disassemble 'hello.c'::main
  Dump of assembler code for function main:
  ... snip ...

But, if I do this:

  (gdb) disassemble hell<TAB>
  (gdb) disassemble hello.c:<CURSOR>

which is a consequence of using the location_completer function.  So
in this commit, after calling skip_over_slash_fmt, I forward the bulk
of the disassemble command completion to expression_completer.  Now
when I try this:

  (gdb) disassemble hell<TAB>

gives nothing, which I think is an improvement.  There is one slight
disappointment, if I do:

  (gdb) disassemble 'hell<TAB>

I still get nothing.  I had hoped that this would expand to:
'hello.c':: but I guess this is a limitation of the current
expression_completer implementation, however, I don't think this is a
regression, the previous expansion was just wrong.  Fixing
expression_completer is out of scope for this commit.

I've added some disassembler command completion tests, and also a test
that disassembling using 'FILE'::FUNC syntax works, as I don't think
that is tested anywhere.

		   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.
