*** Changes since GDB 7.10
+* Record btrace now supports non-stop mode.
+
* Support for tracepoints on aarch64-linux was added in GDBserver.
* The 'record instruction-history' command now indicates speculative execution
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:
target dbug dBUG ROM monitor for Motorola ColdFire
* Support for reading/writing memory and extracting values on architectures
whose memory is addressable in units of any integral multiple of 8 bits.
+* New remote packets
+
+exec stop reason
+ Indicates that an exec system call was executed.
+
+exec-events feature in qSupported
+ The qSupported packet allows GDB to request support for exec
+ events using the new 'gdbfeature' exec-event, and the qSupported
+ response can contain the corresponding 'stubfeature'. Set and
+ show commands can be used to display whether these features are enabled.
+
+* Extended-remote exec events
+
+ ** GDB now has support for exec events on extended-remote Linux targets.
+ For such targets with Linux kernels 2.5.46 and later, this enables
+ follow-exec-mode and exec catchpoints.
+
+set remote exec-event-feature-packet
+show remote exec-event-feature-packet

-maint show target-non-stop
- Control whether GDB targets always operate in non-stop mode even if
- "set non-stop" is "off". The default is "auto", meaning non-stop
- mode is enabled if supported by the target.
