2018-09-09  Cesar Philippidis  <cesar@codesourcery.com>
	    Julian Brown  <julian@codesourcery.com>

	PR middle-end/86336

	gcc/cp/
	* semantics.c (finish_omp_clauses): Treat C++ references the same in
	OpenACC as OpenMP.

	gcc/
	* gimplify.c (gimplify_scan_omp_clauses): Set
	target_firstprivatize_array_bases in OpenACC parallel and kernels
	region contexts.  Remove GOMP_MAP_FIRSTPRIVATE_REFERENCE clauses from
	OpenACC data regions.

	libgomp/
	* testsuite/libgomp.oacc-c++/non-scalar-data.C: Remove XFAIL.
