--- Comment #1 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
Relatedly, since r228777 "Merge from gomp-4_1-branch to trunk" ("which brings
in most of the OpenMP 4.5 support for C and C++"), the following optimization
is done:
case OMP_TARGET_ENTER_DATA:
case OMP_TARGET_EXIT_DATA:
case OACC_ENTER_DATA:
case OACC_EXIT_DATA:
case OACC_HOST_DATA:
if (OMP_CLAUSE_MAP_KIND (c) == GOMP_MAP_FIRSTPRIVATE_POINTER
|| (OMP_CLAUSE_MAP_KIND (c)
== GOMP_MAP_FIRSTPRIVATE_REFERENCE))
/* For target {,enter ,exit }data only the array slice is
mapped, but not the pointer to it. */
remove = true;
break;
Why is this not applicable for OpenACC '!$acc update'/OpenMP '!$omp target
update', too? (This is now also relevant for C/C++.)
