*** Changes since GDB 8.3
+* 'thread-exited' event is now available in the annotations interface.
+
* New built-in convenience variables $_gdb_major and $_gdb_minor
provide the GDB version. They are handy for conditionally using
features available only in or since specific GDB versions, in
* Support for Pointer Authentication on AArch64 Linux.
-* Two new convernience functions $_cimag and $_creal that extract the
+* Two new convenience functions $_cimag and $_creal that extract the
imaginary and real parts respectively from complex numbers.
* Python API
'array_indexes', 'symbols', 'unions', 'deref_refs', 'actual_objects',
'static_members', 'max_elements', 'repeat_threshold', and 'format'.
+ ** gdb.Type has a new property 'objfile' which returns the objfile the
+ type was defined in.
+
+* New built-in convenience variables $_shell_exitcode and $_shell_exitsignal
+ provide the exitcode or exit status of the shell commands launched by
+ GDB commands such as "shell", "pipe" and "make".
+
* New commands
+| [COMMAND] | SHELL_COMMAND
+| -d DELIM COMMAND DELIM SHELL_COMMAND
+pipe [COMMAND] | SHELL_COMMAND
+pipe -d DELIM COMMAND DELIM SHELL_COMMAND
+ Executes COMMAND and sends its output to SHELL_COMMAND.
+ With no COMMAND, repeat the last executed command
+ and send its output to SHELL_COMMAND.
+
set may-call-functions [on|off]
show may-call-functions
This controls whether GDB will attempt to call functions in
an error when a command (such as print expression) calls a function
in the program.
+set print finish [on|off]
+show print finish
+ This controls whether the `finish' command will display the value
+ that is returned by the current function. When `off', the value is
+ still entered into the value history, but it is not printed. The
+ default is `on'.
+
+set print max-depth
+show print max-depth
+ Allows deeply nested structures to be simplified when printing by
+ replacing deeply nested parts (beyond the max-depth) with ellipses.
+ The default max-depth is 20, but this can be set to unlimited to get
+ the old behavior back.
+
+set logging debugredirect [on|off]
+ By default, GDB debug output will go to both the terminal and the logfile.
+ Set if you want debug output to go only to the log file.
+
+set style title foreground COLOR
+set style title background COLOR
+set style title intensity VALUE
+ Control the styling of titles.
+
+set style highlight foreground COLOR
+set style highlight background COLOR
+set style highlight intensity VALUE
+ Control the styling of highlightings.
+
+* Changed commands
+
+help
+ The "help" command uses the title style to enhance the
+ readibility of its output by styling the classes and
+ command names.
+
+apropos [-v] REGEXP
+ Similarly to "help", the "apropos" command also uses the
+ title style for the command names. "apropos" accepts now
+ a flag "-v" (verbose) to show the full documentation
+ of matching commands and to use the highlight style to mark
+ the documentation parts matching REGEXP.
+
+show style
+ The "show style" and its subcommands are now styling
+ a style name in their output using its own style, to help
+ the user visualize the different styles.
+
+
+* New MI commands
+
+-complete
+ This lists all the possible completions for the rest of the line, if it
+ were to be given as a command itself. This is intended for use by MI
+ frontends in cases when separate CLI and MI channels cannot be used.
+
+* Testsuite
+
+ The testsuite now creates the files gdb.cmd (containing the arguments
+ used to launch GDB) and gdb.in (containing all the commands sent to
+ GDB) in the output directory for each test script. Multiple invocations
+ are appended with .1, .2, .3 etc.
+
