-@cindex reloading symbols
-Some systems allow individual object files that make up your program to
-be replaced without stopping and restarting your program.  For example,
-in VxWorks you can simply recompile a defective object file and keep on
-running.  If you are running on one of these systems, you can allow
-@value{GDBN} to reload the symbols for automatically relinked modules:
-
-@table @code
-@kindex set symbol-reloading
-@item set symbol-reloading on
-Replace symbol definitions for the corresponding source file when an
-object file with a particular name is seen again.
-
-@item set symbol-reloading off
-Do not replace symbol definitions when encountering object files of the
-same name more than once.  This is the default state; if you are not
-running on a system that permits automatic relinking of modules, you
-should leave @code{symbol-reloading} off, since otherwise @value{GDBN}
-may discard symbols when linking large programs, that may contain
-several modules (from different directories or libraries) with the same
-name.
