        * sh.md (floatsisf2_i4, floatsidf2_i, extendsfdf2_i4): Use it for
        input operand that needs to be in fpul.
        (fix_truncsfsi2, fix_truncsfsi2_i4): Use register_operand for output.
+       * sh.c (find_barrier): Take into account that machine_dependent_reorg
+       might add new insns.
