  br label %L3

L3:                                               ; preds = %L13, %top
  %value_phi = phi ptr [ null, %top ], [ %0, %L13 ]
  %0 = getelementptr i8, ptr %value_phi, i64 8
  %.not = icmp ule ptr %value_phi, null
  br i1 %.not, label %L13, label %L15

L13:                                              ; preds = %L3
