+ * trans-expr.c (gfc_trans_assignment_1): Set OMPWS_SCALARIZER_WS
+ bit in ompws_flags only if loop.temp_ss is NULL, and clear it if
+ lhs needs reallocation.
+ * trans-openmp.c (gfc_trans_omp_workshare): Don't return early if
+ code is NULL, emit a barrier if workshare emitted no code at all
+ and NOWAIT clause isn't present.
