architectures require kernel changes. TLS is not yet supported for
amd64 and i386 process core dumps.
-* Support for Pointer Authentication on AArch64 Linux.
+* Support for Pointer Authentication (PAC) on AArch64 Linux. Return
+ addresses that required unmasking are shown in the backtrace with the
+ postfix [PAC].
* Two new convenience functions $_cimag and $_creal that extract the
imaginary and real parts respectively from complex numbers.
** gdb.Type has a new property 'objfile' which returns the objfile the
type was defined in.
+ ** The frame information printed by the python frame filtering code
+ is now consistent with what the 'backtrace' command prints when
+ there are no filters, or when the 'backtrace' '-no-filters' option
+ is given.
+
+ ** The new function gdb.lookup_static_symbol can be used to look up
+ symbols with static linkage.
+
+ ** gdb.Objfile has new methods 'lookup_global_symbol' and
+ 'lookup_static_symbol' to lookup a symbol from this objfile only.
+
+ ** gdb.Block now supports the dictionary syntax for accessing symbols in
+ this block (e.g. block['local_variable']).
+
* New commands
| [COMMAND] | SHELL_COMMAND
A set of commands used by the testsuite for exercising the settings
infrastructure.
+set print frame-info [short-location|location|location-and-address
+ |source-and-location|source-line|auto]
+show print frame-info
+ This controls what frame information is printed by the commands printing
+ a frame. This setting will e.g. influence the behaviour of 'backtrace',
+ 'frame', 'stepi'. The python frame filtering also respect this setting.
+ The 'backtrace' '-frame-info' option can override this global setting.
+
* Changed commands
help
This allows to do formatted printing of strings without having
a running inferior, or when debugging a core dump.
+info sources [-dirname | -basename] [--] [REGEXP]
+ This command has now optional arguments to only print the files
+ whose names match REGEXP. The arguments -dirname and -basename
+ allow to restrict matching respectively to the dirname and basename
+ parts of the files.
+
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.
+set print frame-arguments
+ The new value 'presence' indicates to only indicate the presence of
+ arguments using ..., instead of printing argument names and values.
+
set print raw-frame-arguments
show print raw-frame-arguments
-entry-values no|only|preferred|if-needed|both|compact|default
-frame-arguments all|scalars|none
-raw-frame-arguments [on|off]
+ -frame-info auto|source-line|location|source-and-location
+ |location-and-address|short-location
-past-main [on|off]
-past-entry [on|off]
-past-main [on|off]
-past-entry [on|off]
+ ** The new "info sources" options -dirname and -basename options
+ are using the standard '-OPT' infrastructure.
+
All options above can also be abbreviated. The argument of boolean
(on/off) options can be 0/1 too, and also the argument is assumed
"on" if omitted. This allows writing compact command invocations,
(gdb) print -raw -pretty -object off -- *myptr
+ ** The "info types" command now supports the '-q' flag to disable
+ printing of some header information in a similar fashion to "info
+ variables" and "info functions".
+
* Completion improvements
** GDB can now complete the options of the "thread apply all" and
GDB) in the output directory for each test script. Multiple invocations
are appended with .1, .2, .3 etc.
+* Building GDB and GDBserver now requires GNU make >= 3.82.
+
+ Using another implementation of the make program or an earlier version of
+ GNU make to build GDB or GDBserver is not supported.
+
*** Changes in GDB 8.3
* GDB and GDBserver now support access to additional registers on
