the entry's @code{mapped} member to determine whether the overlay is
currently mapped.
In addition, your overlay manager may define a function called
@var{_ovly_debug_event}. If this function is defined, @value{GDBN}
will silently set a breakpoint there. If the overlay manager then
calls this function whenever it has changed the overlay table, this
will enable @value{GDBN} to accurately keep track of which overlays
are in program memory, and update any breakpoints that may be set
in overlays. This will allow breakpoints to work even if the
overlays are kept in ROM or other non-writable memory while they
are not being executed.
