GDB 4.18 is released!
Version 4.18 of GDB, the GNU Debugger, is now available via anonymous FTP.
GDB is a source-level debugger for C, C++, and many other languages. GDB can
target (i.e. debug programs running on) dozens of different processor
architectures, and GDB itself can run on GNU/Linux, Windows NT,
Windows 95, and most popular Unix variants.
You can download GDB from either Project GNU's FTP server or any of its
mirrors, or Cygnus's Sourceware site:
ftp://ftp.gnu.org/pub/gnu/gdb
ftp://sourceware.cygnus.com/pub/gdb
(See the end of this message for a complete list of GNU ftp mirrors.)
The previous version, 4.17, was released about a year ago; there have been
many changes and additions since then. Details are below.

There is a web page for GDB at:
http://sourceware.cygnus.com/gdb/
That page includes information about GDB mailing lists (an announcement
mailing list, developers discussion lists, etc.), locations for development
snapshots, preformatted documentation, and links to related information
around the net. We will put errata notes and host-specific tips for this
release on-line as any problems come up. All mailing lists archives are also
browsable via the web.
Many people have contributed to this release. Thanks to everybody for the
help!
Keep those fixes and improvements coming in! (Send them to bug-gdb@gnu.org)

*** Changes in GDB-4.18:
* New native configurations
HP-UX 10.20 hppa*-*-hpux10.20
HP-UX 11.x hppa*-*-hpux11.0*
M68K Linux m68*-*-linux*
* New targets
Fujitsu FR30 fr30-*-elf*
Intel StrongARM strongarm-*-*
Mitsubishi D30V d30v-*-*
* OBSOLETE configurations
Gould PowerNode, NP1 np1-*-*, pn-*-*
Configurations that have been declared obsolete will be commented out,
but the code will be left in place. If there is no activity to revive
these configurations before the next release of GDB, the sources will
be permanently REMOVED.
* ANSI/ISO C
As a compatibility experiment, GDB's source files buildsym.h and
buildsym.c have been converted to pure standard C, no longer
containing any K&R compatibility code. We believe that all systems in
use today either come with a standard C compiler, or have a GCC port
available. If this is not true, please report the affected
configuration to bug-gdb@gnu.org immediately. See the README file for
information about getting a standard C compiler if you don't have one
already.
* Readline 2.2
GDB now uses readline 2.2.
* set extension-language
You can now control the mapping between filename extensions and source
languages by using the `set extension-language' command. For instance,
you can ask GDB to treat .c files as C++ by saying
set extension-language .c c++
The command `info extensions' lists all of the recognized extensions
and their associated languages.
* Setting processor type for PowerPC and RS/6000
When GDB is configured for a powerpc*-*-* or an rs6000*-*-* target,
you can use the `set processor' command to specify what variant of the
PowerPC family you are debugging. The command
set processor NAME
sets the PowerPC/RS6000 variant to NAME. GDB knows about the
following PowerPC and RS6000 variants:
ppc-uisa PowerPC UISA - a PPC processor as viewed by user-level code
rs6000 IBM RS6000 ("POWER") architecture, user-level view
403 IBM PowerPC 403
403GC IBM PowerPC 403GC
505 Motorola PowerPC 505
860 Motorola PowerPC 860 or 850
601 Motorola PowerPC 601
602 Motorola PowerPC 602
603 Motorola/IBM PowerPC 603 or 603e
604 Motorola PowerPC 604 or 604e
750 Motorola/IBM PowerPC 750 or 750
At the moment, this command just tells GDB what to name the
special-purpose processor registers. Since almost all the affected
registers are inaccessible to user-level programs, this command is
only useful for remote debugging in its present form.
* HP-UX support
Thanks to a major code donation from Hewlett-Packard, GDB now has much
more extensive support for HP-UX. Added features include shared
library support, kernel threads and hardware watchpoints for 11.00,
support for HP's ANSI C and C++ compilers, and a compatibility mode
for xdb and dbx commands.
* Catchpoints
HP's donation includes the new concept of catchpoints, which is a
generalization of the old catch command. On HP-UX, it is now possible
to catch exec, fork, and vfork, as well as library loading.
This means that the existing catch command has changed; its first
argument now specifies the type of catch to be set up. See the
output of "help catch" for a list of catchpoint types.
* Debugging across forks
On HP-UX, you can choose which process to debug when a fork() happens
in the inferior.
* TUI
HP has donated a curses-based terminal user interface (TUI). To get
it, build with --enable-tui. Although this can be enabled for any
configuration, at present it only works for native HP debugging.
* GDB remote protocol additions
A new protocol packet 'X' that writes binary data is now available.
Default behavior is to try 'X', then drop back to 'M' if the stub
fails to respond. The settable variable `remotebinarydownload'
allows explicit control over the use of 'X'.
For 64-bit targets, the memory packets ('M' and 'm') can now contain a
full 64-bit address. The command
set remoteaddresssize 32
can be used to revert to the old behaviour. For existing remote stubs
the change should not be noticed, as the additional address information
will be discarded.
In order to assist in debugging stubs, you may use the maintenance
command `packet' to send any text string to the stub. For instance,
maint packet heythere
sends the packet "$heythere#". Note that it is very easy to
disrupt a debugging session by sending the wrong packet at the wrong
time.
The compare-sections command allows you to compare section data on the
target to what is in the executable file without uploading or
downloading, by comparing CRC checksums.
* Tracing can collect general expressions
You may now collect general expressions at tracepoints. This requires
further additions to the target-side stub; see tracepoint.c and
doc/agentexpr.texi for further details.
* mask-address variable for Mips
For Mips targets, you may control the zeroing of the upper 32 bits of
a 64-bit address by entering `set mask-address on'. This is mainly
of interest to users of embedded R4xxx and R5xxx processors.
* Higher serial baud rates
GDB's serial code now allows you to specify baud rates 57600, 115200,
230400, and 460800 baud. (Note that your host system may not be able
to achieve all of these rates.)
* i960 simulator
The i960 configuration now includes an initial implementation of a
builtin simulator, contributed by Jim Wilson.
