Don't allocate the array on the stack if so. Don't call malloc for zero-sized arrays. (gfc_trans_allocate_temp_array): Add a similar argument here. Pass it along to gfc_trans_allocate_array_storage.

(gfc_trans_array_constructor_value): Likewise. (gfc_get_array_cons_size): Delete. (gfc_trans_array_constructor): If the loop bound has not been set, split the allocation into a static part and a dynamic part. Set loop->to to the bounds for static part before allocating the temporary. Adjust call to gfc_trans_array_constructor_value. (gfc_conv_loop_setup): Allow any constructor to determine the loop bounds. Check whether the constructor has a dynamic size and prefer to use something else if so. Expect the loop bound to be set later. Adjust call to gfc_trans_allocate_temp_array. * trans-expr.c (gfc_conv_function_call): Adjust another call here. From-SVN: r104073
