This patch was previously approved here, but I have not committed it yet
(without the other patches in this series):

  https://gcc.gnu.org/ml/gcc-patches/2019-10/msg01156.html

Included for completeness. I will commit this alongside other patches
if they are approved (or it could probably go in by itself anyway).

Thanks,

Julian

ChangeLog

	libgomp/
	* libgomp.h (gomp_map_val): Add prototype.
	* oacc-parallel.c (GOACC_parallel_keyed): Use gomp_map_val instead of
	open-coding device-address calculation.
	* target.c (gomp_map_val): Make global.
