This patch overwrites

I optimized it a little bit. We don't need to do the check if the
shared library is still being loaded/unloaded.

Based on patches from Sam Lantinga (slouken@devolution.com):
* solib.c (solib_verify): New function. Reload list of shared
objects when they are added or deleted and dump symbols from
unloaded shared objects.
* solib.h (SOLIB_VERIFY): New. Defined as solib_verify.
* infrun.c (handle_inferior_event): Also call SOLIB_VERIFY ()
if it is defined when we hit the internal debug breakpoint for
shared libraries in the dynamic linker.

I've just committed a pile of changes to the manual. This includes
the duplication of the top-level menu for the benefit of @ifhtml,
the re-removal of node links, and various formatting changes to
make @smallbook come out right (as requested by Brian Youmans).
I tested on 3.12, 3.12h (RH 6.1 version), and 4.0. Apparently
texi2html has a problem with the top-level menu that is under
@ifhtml, and it gets garbled, although 4.0 makeinfo -html works
fine (but it can only make one monster html file, sigh). It's
functionally no worse than before, but looks bad.
I'm still planning to rewrite the introduction to use a more
meaningful example program, and we still have undocumented
commands that ought to be mentioned, so this isn't the end,
but this should be a good base for the next round of tweaks.
(I left the remote protocol section mostly untouched, since JT
has a patch to apply.)

2000-03-28 Stan Shebs <shebs@apple.com>
* gdb.texinfo: Update dates, bump to Eighth Edition (note
expectation of additional changes before release), update
ISBN, add copy of top-level menu for @ifhtml, remove explicit
node links, rephrase and/or shorten lines to fix formatting
problem in both regular and @smallbook formats.
* annotate.texi: Shorten lines in example, use smallexample
consistently everywhere.
* Makefile.in: Add comment about texinfo 4.0 html generation.
(SFILES_INCLUDED): Add annotate.texi.

Thanks for tracking this down. It looks like gdb_thread_select should
still be defined as a global to accomodate some not-ready-for-release
code dealing with threads.
So, I've added the declaration to a header file.

Hi guys,
I've checked the following patch to arm-linux-nat.c in. This just cleans up
some build warnings and naming of functions.
2000-02-28 Scott Bambrough <scottb@netwinder.org>
* arm-linux-nat.c (fetch_nw_fpe_*):
Renamed to fetch_nwfpe_* to use the same naming convention
as in the Linux kernel. Modified prototype to get rid of
unused parameters.
(store_nw_fpe_*): Renamed to store_nwfpe_* to use the same
naming convention as in the Linux kernel. Fixed calls to
fetch_nwfpe_*.
(store_fpregs): Fixed calls to store_nwfpe_*. Removed
unused variable.

Subject: ARM patch -- extra info about cpsr register
Date: Sat, 01 Apr 2000 00:00:00 -0000

Time I sorted out some of my local changes...
This patch provides a useful additional decoding of the CPSR register for
ARM ports of GDB for commands such as "info reg". It translates the
setting of the CPSR into a set of mnemonic letters representing the
settings of the various flag bits as documented in the data sheet (upper
case for set bits, lower case for clear bits) -- generally I find this
much more intelligible than the raw numbers.
<date> Richard Earnshaw (rearnsha@arm.com)
* arm-tdep.c (arm_print_register_hook): New function.
* arm/tm-arm.h (PRINT_REGISTER_HOOK): Call it.
(FLAG_*): New bits in CPSR.
