*** 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
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. The feature is currently
- supported by the i386-linux and amd64-linux builds.
+ - 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
* Python scripting
+** GDB now provides a new directory location, called the python directory,
+ where Python scripts written for GDB can be installed. The location
+ of that directory is <data-directory>/python, where <data-directory>
+ is the GDB data directory. For more details, see section `Scripting
+ GDB using Python' in the manual.
+
** The GDB Python API now has access to breakpoints, symbols, symbol
- tables, program spaces, and frame's code blocks.
+ tables, program spaces, inferiors, threads and frame's code blocks.
+ Additionally, GDB Parameters can now be created from the API, and
+ manipulated via set/show in the CLI.
** New functions gdb.target_charset, gdb.target_wide_charset,
- gdb.progspaces, and gdb.current_progspace.
+ 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
tracepoints and the "commands" command can be used for both tracepoints and
ARM Symbian arm*-*-symbianelf*
+* D language support.
+ GDB now supports debugging programs written in the D programming
+ language.
