*** Changes since GDB 7.2
+* GDB has a new command: "thread find [REGEXP]".
+ It finds the thread id whose name, target id, or thread extra info
+ matches the given regular expression.
+
+* The "catch syscall" command now works on mips*-linux* targets.
+
+* The -data-disassemble MI command now supports modes 2 and 3 for
+ dumping the instruction opcodes.
+
+* New command line options
+
+-data-directory DIR Specify DIR as the "data-directory".
+ This is mostly for testing purposes.
+
+* The "maint set python auto-load on|off" command has been renamed to
+ "set auto-load-scripts on|off".
+
* GDB has a new command: "set directories".
It is like the "dir" command except that it replaces the
source path list instead of augmenting it.
+* GDB now understands thread names.
+
+ On GNU/Linux, "info threads" will display the thread name as set by
+ prctl or pthread_setname_np.
+
+ There is also a new command, "thread name", which can be used to
+ assign a name internally for GDB to display.
+
* OpenCL C
Initial support for the OpenCL C language (http://www.khronos.org/opencl)
has been integrated into GDB.
* Python scripting
+ ** Breakpoints can now be sub-classed in Python, and in particular
+ you may implement a 'stop' function that is executed each time
+ the inferior reaches that breakpoint.
+
+ ** New function gdb.lookup_global_symbol looks up a global symbol.
+
** GDB values in Python are now callable if the value represents a
function. For example, if 'some_value' represents a function that
takes two integer parameters and returns a value, you can call
** gdb.parameter("directories") is now available.
+ ** New function gdb.newest_frame returns the newest frame in the
+ selected thread.
+
+ ** The gdb.InferiorThread class has a new "name" attribute. This
+ holds the thread's name.
+
+ ** Python Support for Inferior events.
+ Python scripts can add observers to be notified of events
+ occurring in the process being debugged.
+ The following events are currently supported:
+ - gdb.events.cont Continue event.
+ - gdb.events.exited Inferior exited event.
+ - gdb.events.stop Signal received, and Breakpoint hit events.
+
* C++ Improvements:
** GDB now puts template parameters in scope when debugging in an
feature requires proper debuginfo support from the compiler; it
was added to GCC 4.5.
+ ** The motion commands "next", "finish", "until", and "advance" now
+ work better when exceptions are thrown. In particular, GDB will
+ no longer lose control of the inferior; instead, the GDB will
+ stop the inferior at the point at which the exception is caught.
+ This functionality requires a change in the exception handling
+ code that was introduced in GCC 4.5.
+
* GDB now follows GCC's rules on accessing volatile objects when
reading or writing target state during expression evaluation.
One notable difference to prior behavior is that "print x = 0"
** GDBserver is now supported on PowerPC LynxOS (versions 4.x and 5.x),
and i686 LynxOS (version 5.x).
+ ** GDBserver is now supported on Blackfin Linux.
+
+* New native configurations
+
+ia64 HP-UX ia64-*-hpux*
+
+* New targets:
+
+Analog Devices, Inc. Blackfin Processor bfin-*
+
* Ada task switching is now supported on sparc-elf targets when
debugging a program using the Ravenscar Profile. For more information,
see the "Tasking Support when using the Ravenscar Profile" section
* Guile support was removed.
+* New features in the GNU simulator
+
+ ** The --map-info flag lists all known core mappings.
+
