Hi, stop_search_p will reach the default case on DEBUG_INSN, and the default case is "gcc_unreachable()". I suppose this means nobody is using DWARF3+ on a dbr_sched target, it can't possibly ever have worked. Eric?
Anyway, also obvious: Don't stop on DEBUG_INSNs. Ciao! Steven * reorg.c (stop_search_p): Don't crash on DEBUG_INSNs.
