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.
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
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
-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) 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
