Very unlikely.  Are you sure it appeared only today and not more than 2
weeks ago with
        PR middle-end/77475
        * toplev.c (process_options): Temporarily set input_location
        to UNKNOWN_LOCATION around targetm.target_option.override () call.
change (also mine)?  All such dg-error lines need to be changed to use
line number 0 (i.e. expect the errors not to be on the first line of the
source which makes no sense, but without any source location, as the errors
appear on the command line, not in any sources).

So it should be
   /* { dg-error "arguments to .-mhotpatch=n,m. should be non-negative integers" "" { target *-*-* } 0 } */
instead.
