A slight rewording:
@kindex set record memory-query
@item set record memory-query
Control the behavior when @value{GDBN} is unable to record memory
changes caused by an instruction. If ON, @value{GDBN} will query
whether to stop the inferior in that case.
If this option is OFF (the default), @value{GDBN} will automatically
ignore the effect of such instructions on memory. Later, when
@value{GDBN} replays this execution log, it will mark the log of this
instruction as not accessible, and it will not affect the replay results.
