--- Comment #1 from Mikael Pettersson <mikpe at it dot uu.se> 2012-01-09 12:44:35 UTC ---
It's caused by r182924:

Author: jakub
Date: Thu Jan  5 20:47:16 2012
New Revision: 182924

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=182924
Log:
    PR debug/51762
    * calls.c (emit_call_1): For noreturn calls force a REG_ARGS_SIZE
    note when !ACCUMULATE_OUTGOING_ARGS.

m68k is !ACCUMULATE_OUTGOING_ARGS, so it triggers this change.
