	(expand_constructor): Save typespec in empty_ts.
	Unset empty_constructor if there is an element.

	and empty_ts.  If there was no explicit constructor
	type and the constructor is empty, take the type from
	empty_ts.

	PR fortran/93162
	* trans-openmp.c (gfc_trans_omp_clauses): Check for REF_ARRAY type
	before testing u.ar.type == AR_FULL.

2020-01-04  Tobias Burnus  <tobias@codesourcery.com>

	PR fortran/91640
	* trans-expr.c (gfc_conv_procedure_call): Avoid copy-out for nonvariable
	arguments to contiguous dummy args.  Avoid re-checking whether fsym is
	NULL.

2020-01-03  Tobias Burnus  <tobias@codesourcery.com>

	* trans-openmp.c (gfc_omp_check_optional_argument): Always return a
	Boolean expression; handle unallocated/disassociated actual arguments
	as absent if passed to nonallocatable/nonpointer dummy array arguments.
	(gfc_build_cond_assign): Change to assume a Boolean expr not a pointer.
	(gfc_omp_finish_clause, gfc_trans_omp_clauses): Assign NULL to generated
	array-data variable if the argument is absent. Simplify code as
	'present' is now a Boolean expression.
