GDB now is able to debug both AArch64 applications and ARM applications
at the same time.
+* Support for fast tracepoints on aarch64-linux was added in GDBserver,
+ including JIT compiling fast tracepoint's conditional expression bytecode
+ into native code.
+
+* GDB now supports displaced stepping on AArch64 GNU/Linux.
+
* New commands
maint set target-non-stop (on|off|auto)
The "/m" option is now considered deprecated: its "source-centric"
output hasn't proved useful in practice.
+* The "set scheduler-locking" command supports a new mode "replay".
+ It behaves like "off" in record mode and like "on" in replay mode.
+
* Support for various ROM monitors has been removed:
