Insight is based on GDB 5.0; the GDB 5.0 release information follows.

------------------------------------

GDB 5.0 is released!

Version 5.0 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 most
popular Unix variants, Windows NT, and Windows 95.

You can download GDB from either Project GNU's FTP server, or Red Hat's
sources site:

         ftp://ftp.gnu.org/gnu/gdb
         ftp://sourceware.cygnus.com/pub/gdb/releases

The previous version, 4.18, was released about a year ago; there have
been many changes and additions since then.  Details below.

*** Changes in GDB 5.0:

* Improved support for debugging FP programs on x86 targets

Unified and much-improved support for debugging floating-point
programs on all x86 targets.  In particular, ``info float'' now
displays the FP registers in the same format on all x86 targets, with
greater level of detail.

* Improvements and bugfixes in hardware-assisted watchpoints

It is now possible to watch array elements, struct members, and
bitfields with hardware-assisted watchpoints.  Data-read watchpoints
on x86 targets no longer erroneously trigger when the address is
written.

* Improvements in the native DJGPP version of GDB

The distribution now includes all the scripts and auxiliary files
necessary to build the native DJGPP version on MS-DOS/MS-Windows
machines ``out of the box''.

The DJGPP version can now debug programs that use signals.  It is
possible to catch signals that happened in the debuggee, deliver
signals to it, interrupt it with Ctrl-C, etc.  (Previously, a signal
would kill the program being debugged.)  Programs that hook hardware
interrupts (keyboard, timer, etc.) can also be debugged.

It is now possible to debug DJGPP programs that redirect their
standard handles or switch them to raw (as opposed to cooked) mode, or
even close them.  The command ``run < foo > bar'' works as expected,
and ``info terminal'' reports useful information about the debuggee's
terminal, including raw/cooked mode, redirection, etc.

The DJGPP version now uses termios functions for console I/O, which
enables debugging graphics programs.  Interrupting GDB with Ctrl-C
also works.

DOS-style file names with drive letters are now fully supported by
GDB.

It is now possible to debug DJGPP programs that switch their working
directory.  It is also possible to rerun the debuggee any number of
times without restarting GDB; thus, you can use the same setup,
breakpoints, etc. for many debugging sessions.

* New native configurations

ARM GNU/Linux                                   arm*-*-linux*
PowerPC GNU/Linux                               powerpc-*-linux*

* New targets

Motorola MCore                                  mcore-*-*
x86 VxWorks                                     i[3456]86-*-vxworks*
PowerPC VxWorks                                 powerpc-*-vxworks*
TI TMS320C80                                    tic80-*-*

* OBSOLETE configurations

Altos 3068                                      m68*-altos-*
Convex                                          c1-*-*, c2-*-*
Pyramid                                         pyramid-*-*
ARM RISCix                                      arm-*-* (as host)
Tahoe                                           tahoe-*-*

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.

* Gould support removed

Support for the Gould PowerNode and NP1 has been removed.

* New features for SVR4

On SVR4 native platforms (such as Solaris), if you attach to a process
without first loading a symbol file, GDB will now attempt to locate and
load symbols from the running process's executable file.

* Many C++ enhancements

C++ support has been greatly improved. Overload resolution now works
properly
in almost all cases. RTTI support is on the way.

* Remote targets can connect to a sub-program

A popen(3) style serial-device has been added.  This device starts a
sub-process (such as a stand-alone simulator) and then communicates
with that.  The sub-program to run is specified using the syntax
``|<program> <args>'' vis:

         (gdb) set remotedebug 1
         (gdb) target extended-remote |mn10300-elf-sim program-args

* MIPS 64 remote protocol

A long standing bug in the mips64 remote protocol where by GDB
expected certain 32 bit registers (ex SR) to be transfered as 32
instead of 64 bits has been fixed.

The command ``set remote-mips64-transfers-32bit-regs on'' has been
added to provide backward compatibility with older versions of GDB.

* ``set remotebinarydownload'' replaced by ``set remote X-packet''

The command ``set remotebinarydownload'' command has been replaced by
``set remote X-packet''.  Other commands in ``set remote'' family
include ``set remote P-packet''.

* Breakpoint commands accept ranges.

The breakpoint commands ``enable'', ``disable'', and ``delete'' now
accept a range of breakpoints, e.g. ``5-7''.  The tracepoint command
``tracepoint passcount'' also accepts a range of tracepoints.

* ``apropos'' command added.

The ``apropos'' command searches through command names and
documentation strings, printing out matches, making it much easier to
try to find a command that does what you are looking for.

* New MI interface

A new machine oriented interface (MI) has been added to GDB.  This
interface is designed for debug environments running GDB as a separate
process.  This is part of the long term libGDB project.  See the
"GDB/MI" chapter of the GDB manual for further information.  It can be
enabled by configuring with:

         .../configure --enable-gdbmi
