GDB 6.8 released!
Release 6.8 of GDB, the GNU Debugger, is now available via
anonymous
FTP. GDB is a source-level debugger for Ada, C, C++,
Objective-C,
Pascal and many other languages. GDB can target (i.e.,
debug programs
running on) more than a dozen different processor
architectures, and GDB
itself can run on most popular GNU/Linux, Unix and Microsoft
Windows
variants.
You can download GDB from the GNU FTP server in the
directory:
ftp://ftp.gnu.org/gnu/gdb

There is a web page for GDB at:
http://www.gnu.org/s
oftware/gdb/
That page includes information about GDB mailing lists (an
announcement
mailing list, developers discussion lists, etc.), details on
how to
access GDB's CVS repository, 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.
GDB 6.8 brings many fixes and enhancements over the previous
major release
(6.7.1, released in October 2007), including:
* GDB now supports the --enable-targets= configure option
to allow
building a single GDB executable that supports multiple
remote
target architectures.
* GDB now supports breakpoints with multiple locations,
including breakpoints on C++ constructors, inside C++
templates,
and in inlined functions.
* GDB now supports debugging C and C++ programs which use
the
Decimal Floating Point extension. In addition, the
PowerPC target
now has a set of pseudo-registers to inspect decimal float
values
stored in two consecutive float registers.
* Improved support for debugging Ada
Many improvements to the Ada language support have been
made. These
include:
- Better support for Ada2005 interface types
- Improved handling of arrays and slices in general
- Better support for Taft-amendment types
- The ' ADDRESS' expression is now allowed on the
left hand-side
of an assignment
- Improved command completion in Ada
- Several bug fixes
* Pending breakpoints no longer change their number when
their address
is resolved.
* GDB's ability to debug optimized code has been improved.
GDB more
accurately identifies function bodies and lexical blocks
that occupy
more than one contiguous range of addresses.
* Target descriptions can now describe registers for
PowerPC.
* GDB on GNU/Linux and HP/UX can now debug through
"exec" of a new process.
The following new commands have been added:
set print frame-arguments (all|scalars|none)
show print frame-arguments
The value of this variable can be changed to control
which argument
values should be printed by the debugger when displaying
a frame.
remote put
remote get
remote delete
Transfer files to and from a remote target, and delete
remote files.
GDB/MI interface improvements:
* The -break-insert MI command can optionally create
pending breakpoints now.
* New MI commands:
-target-file-put
-target-file-get
-target-file-delete
Transfer files to and from a remote target, and delete
remote files.
Support for the following new native configurations have
been added:
x86/Windows i[34567]86-*-mingw32*
NetBSD/hppa hppa*-*netbsd*
Xtensa GNU/Linux xtensa*-*-linux*
Support for the following targets has been added:
NetBSD/hppa hppa*-*-netbsd*
Xtensa GNU/Linux xtensa*-*-linux*
The following improvements were made to gdbserver, the GDB
remote stub:
* Target descriptions can now describe registers for
PowerPC
* Support for AltiVec and SPE registers have been added
* Thread debugger on GNU/Linux has been added even when
libthread_db
is not available.
* New file transfer commands introduced (remote put,
remote get, and
remote delete)
* Support for run and attach in extended-remote mode.
Some other removed features:
* Attaching to a program using the '-c' command line
switch is no longer
supported. Instead, using the '-p' or '--pid' option.
