provide the exitcode or exit status of the shell commands launched by
GDB commands such as "shell", "pipe" and "make".
+* The RX port now supports XML target descriptions.
+
+* GDB now shows the Ada task names at more places, e.g. in task switching
+ messages.
+
+* GDB can now be compiled with Python 3 on Windows.
+
+* New convenience variable $_ada_exception holds the address of the
+ Ada exception being thrown. This is set by Ada-related catchpoints.
+
+* GDB can now place breakpoints on nested functions and subroutines in
+ Fortran code. The '::' operator can be used between parent and
+ child scopes when placing breakpoints, for example:
+
+ (gdb) break outer_function::inner_function
+
+ The 'outer_function::' prefix is only needed if 'inner_function' is
+ not visible in the current scope.
+
* Python API
** The gdb.Value type has a new method 'format_string' which returns a
Commands used by the testsuite to validate the command options
framework.
+focus, winheight, +, -, >, <
+ These commands are now case-sensitive.
+
* New command options, command completion
GDB now has a standard infrastructure to support dash-style command
printing of some header information in a similar fashion to "info
variables" and "info functions".
+ ** The "info variables", "info functions", and "whereis" commands
+ now take a '-n' flag that excludes non-debug symbols (symbols
+ from the symbol table, not from the debug info such as DWARF)
+ from the results.
+
* Completion improvements
** GDB can now complete the options of the "thread apply all" and
These can be used to catch C++ exceptions in a similar fashion to
the CLI commands 'catch throw', 'catch rethrow', and 'catch catch'.
+* Other MI changes
+
+ ** The default version of the MI interpreter is now 3 (-i=mi3).
+
+ ** The output of information about multi-location breakpoints (which is
+ syntactically incorrect in MI 2) has changed in MI 3. This affects
+ the following commands and events:
+
+ - -break-insert
+ - -break-info
+ - =breakpoint-created
+ - =breakpoint-modified
+
+ The -fix-multi-location-breakpoint-output command can be used to enable
+ this behavior with previous MI versions.
+
+ ** Backtraces and frames include a new optional field addr_flags which is
+ given after the addr field. On AArch64 this contains PAC if the address
+ has been masked in the frame. On all other targets the field is not
+ present.
+
* Testsuite
The testsuite now creates the files gdb.cmd (containing the arguments
GDB now bundles GNU readline 8.0, but if you choose to use
--with-system-readline, only readline >= 7.0 can be used.
+* The TUI SingleKey keymap is now named "SingleKey". This can be used
+ from .inputrc to bind keys in this keymap. This feature is only
+ available when gdb is built against GNU readline 8.0 or later.
+
+* Removed targets and native configurations
+
+ GDB no longer supports debugging the Cell Broadband Engine. This includes
+ both debugging standalone Cell/B.E. SPU applications and integrated debugging
+ of Cell/B.E. applications that use both the PPU and SPU architectures.

*** Changes in GDB 8.3
* GDB and GDBserver now support access to additional registers on
* MI changes
- ** The default version of the MI interpreter is now 3 (-i=mi3).
-
** The '-data-disassemble' MI command now accepts an '-a' option to
disassemble the whole function surrounding the given program
counter value or function name. Support for this feature can be
** Command responses and notifications that include a frame now include
the frame's architecture in a new "arch" attribute.
- ** The output of information about multi-location breakpoints (which is
- syntactically incorrect in MI 2) has changed in MI 3. This affects
- the following commands and events:
-
- - -break-insert
- - -break-info
- - =breakpoint-created
- - =breakpoint-modified
-
- The -fix-multi-location-breakpoint-output command can be used to enable
- this behavior with previous MI versions.
