*** Changes since GDB 7.1
+* C++ Improvements:
+
+ ** Argument Dependent Lookup (ADL)
+
+ In C++ ADL lookup directs function search to the namespaces of its
+ arguments even if the namespace has not been imported.
+ For example:
+ namespace A
+ {
+ class B { };
+ void foo (B) { }
+ }
+ ...
+ A::B b
+ foo(b)
+ Here the compiler will search for `foo' in the namespace of 'b'
+ and find A::foo. GDB now supports this. This construct is commonly
+ used in the Standard Template Library for operators.
+
+ ** Improved User Defined Operator Support
+
+ In addition to member operators, GDB now supports lookup of operators
+ defined in a namespace and imported with a `using' directive, operators
+ defined in the global scope, operators imported implicitly from an
+ anonymous namespace, and the ADL operators mentioned in the previous
+ entry.
+ GDB now also supports proper overload resolution for all the previously
+ mentioned flavors of operators.
+
+* Windows Thread Information Block access.
+
+ On Windows targets, GDB now supports displaying the Windows Thread
+ Information Block (TIB) structure. This structure is visible either
+ by using the new command `info w32 thread-information-block' or, by
+ dereferencing the new convenience variable named `$_tlb', a
+ thread-specific pointer to the TIB. This feature is also supported
+ when remote debugging using GDBserver.
+
+* New remote packets
+
+qGetTIBAddr
+
+ Return the address of the Windows Thread Information Block of a given thread.
+
+qRelocInsn
+
+ In response to several of the tracepoint packets, the target may now
+ also respond with a number of intermediate `qRelocInsn' request
+ packets before the final result packet, to have GDB handle
+ relocating an instruction to execute at a different address. This
+ is particularly useful for stubs that support fast tracepoints. GDB
+ reports support for this feature in the qSupported packet.
+
+* The source command now accepts a -s option to force searching for the
+ script in the source search path even if the script name specifies
+ a directory.
+
+* New features in the GDB remote stub, GDBserver
+
+ - GDBserver now support tracepoints (including fast tracepoints).
+ The feature is currently supported by the i386-linux and
+ amd64-linux builds. See the "Tracepoints support in gdbserver"
+ section in the manual for more information. GDBserver JIT
+ compiles the tracepoint's conditional agent expression bytecode
+ into native code whenever possible for low overhead dynamic
+ tracepoints conditionals. For such tracepoints, an expression
+ that examines program state is evaluated when the tracepoint is
+ reached, in order to determine whether to capture trace data. If
+ the condition is simple and false, processing the tracepoint
+ finishes very quickly and no data is gathered.
+
+ - GDBserver now supports x86_64 Windows 64-bit debugging.
+
* GDB now sends xmlRegisters= in qSupported packet to indicate that
it understands register description.
single `break' command creates multiple breakpoints (e.g.,
breakpoints on overloaded c++ functions).
+* The `rbreak' command now accepts a filename specification as part of
+ its argument, limiting the functions selected by the regex to those
+ in the specified file.
+
+* Support for remote debugging Windows and SymbianOS shared libraries
+ from Unix hosts has been improved. Non Windows GDB builds now can
+ understand target reported file names that follow MS-DOS based file
+ system semantics, such as file names that include drive letters and
+ use the backslash character as directory separator. This makes it
+ possible to transparently use the "set sysroot" and "set
+ solib-search-path" on Unix hosts to point as host copies of the
+ target's shared libraries. See the new command "set
+ target-file-system-kind" described below, and the "Commands to
+ specify files" section in the user manual for more information.
+
+* New commands
+
+eval template, expressions...
+ Convert the values of one or more expressions under the control
+ of the string template to a command line, and call it.
+
+set target-file-system-kind unix|dos-based|auto
+show target-file-system-kind
+ Set or show the assumed file system kind for target reported file
+ names.
+
+save breakpoints <filename>
+ Save all current breakpoint definitions to a file suitable for use
+ in a later debugging session. To read the saved breakpoint
+ definitions, use the `source' command.
+
+`save tracepoints' is a new alias for `save-tracepoints'. The latter
+is now deprecated.
+
* Python scripting
** The GDB Python API now has access to breakpoints, symbols, symbol
- tables, and frame's code blocks.
+ tables, program spaces, and frame's code blocks. Additionally, GDB
+ Parameters can now be created from the API, and manipulated via
+ set/show in the CLI.
-** New methods gdb.target_charset and gdb.target_wide_charset.
+** New functions gdb.target_charset, gdb.target_wide_charset,
+ gdb.progspaces, gdb.current_progspace, and gdb.string_to_argv.
+
+** New exception gdb.GdbError.
+
+** Pretty-printers are now also looked up in the current program space.
+
+** Pretty-printers can now be individually enabled and disabled.
+
+** GDB now looks for names of Python scripts to auto-load in a
+ special section named `.debug_gdb_scripts', in addition to looking
+ for a OBJFILE-gdb.py script when OBJFILE is read by the debugger.
* Tracepoint actions were unified with breakpoint commands. In particular,
there are no longer differences in "info break" output for breakpoints and
ARM Symbian arm*-*-symbianelf*
+* D language support.
+ GDB now supports debugging programs written in the D programming
+ language.
