Andrew Burgess 48a0a7ca5e gdb: fix 'maint info inline-frames' after 'stepi'
There is an invalid assumption within 'maint info inline-frames' which
triggers an assert:

  (gdb) stepi
  0x000000000040119d	18	  printf ("Hello World\n");
  (gdb) maintenance info inline-frames
  ../../src/gdb/inline-frame.c:554: internal-error: maintenance_info_inline_frames: Assertion `it != inline_states.end ()' failed.
  A problem internal to GDB has been detected,
  further debugging may prove unreliable.
  ----- Backtrace -----
  ... etc ...

The problem is this assert:

  /* Stopped threads always have cached inline_state information.  */
  gdb_assert (it != inline_states.end ());

If you check out infrun.c and look in handle_signal_stop for the call
to skip_inline_frames then you'll find a rather large comment that
explains that we don't always compute the inline state information for
performance reasons.  So the assertion is not valid.

I've updated the code so that if there is cached information we use
that, but if there is not then we just create our own information for
the current $pc of the current thread.

This means that, if there is cached information, GDB still correctly
shows which frame the inferior is in (it might not be in the inner
most frame).

If there is no cached information we will always display the inferior
as being in the inner most frame, but that's OK, because if
skip_inline_frames has not been called then GDB will have told the
user they are in the inner most frame, so everything lines up.

I've extended the test to check 'maint info inline-frames' after a
stepi which would previously have triggered the assertion.

		   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.
