[Bug fortran/30273] gfc_todo: Not Implemented: Unable to determine rank of expression

Harald,

I found it in a couple of minutes; the dependency analysis does not know about
NULL(), decides the worst and makes a mess of it!

Index: gcc/fortran/dependency.c
===================================================================
*** gcc/fortran/dependency.c    (révision 120108)
--- gcc/fortran/dependency.c    (copie de travail)
*************** gfc_check_dependency (gfc_expr * expr1,
*** 700,705 ****
--- 700,708 ----
        /* Probably ok in the majority of (constant) cases.  */
        return 1;

+     case EXPR_NULL:
+       return 0;
+
      default:
        return 1;
      }

Fixes the problem.

I'll regtest when I get home and will submit tonight.

Paul
