+displaced stepping to step over breakpoints.
+
+@item set displaced-stepping off
+@value{GDBN} will not use displaced stepping to step over breakpoints,
+even if such is supported by the target architecture.
+
+@cindex non-stop mode, and @samp{set displaced-stepping}
+@item set displaced-stepping auto
+This is the default mode.  @value{GDBN} will use displaced stepping
+only if non-stop mode is active (@pxref{Non-Stop Mode}) and the target
+architecture supports displaced stepping.
