3932         * doc/invoke.texi (Optimize Options): Refer to "unit-at-a-time
3933         mode" rather than "-funit-at-a-time" since -O2 enables it
3934         without requiring -f* options.  Refer to -fprofile-generate and
3935         -fprofile-use correctly.  Move -funit-at-a-time among options
3936         enabled by -O.  Add information about unit-at-a-time caveats.
