gcc/c/
* c-parser.c (OACC_HOST_DATA_CLAUSE_MASK): Add PRAGMA_OACC_CLAUSE_IF
and PRAGMA_OACC_CLAUSE_IF_PRESENT.
gcc/cp/
* parser.c (OACC_HOST_DATA_CLAUSE_MASK): Add PRAGMA_OACC_CLAUSE_IF
and PRAGMA_OACC_CLAUSE_IF_PRESENT.
gcc/fortran/
* openmp.c (OACC_HOST_DATA_CLAUSES): Add PRAGMA_OACC_CLAUSE_IF
and PRAGMA_OACC_CLAUSE_IF_PRESENT.
gcc/
* omp-low.c (lower_omp_target): Use GOMP_MAP_USE_DEVICE_PTR_IF_PRESENT
if PRAGMA_OACC_CLAUSE_IF_PRESENT exist.
gcc/testsuite/
* c-c++-common/goacc/host_data-1.c: Added tests of if and if_present
clauses on host_data.
* gfortran.dg/goacc/host_data-tree.f95: Likewise.
include/
* gomp-constants.h (enum gomp_map_kind): New enumeration constant
GOMP_MAP_USE_DEVICE_PTR_IF_PRESENT.
libgomp/
* oacc-parallel.c (GOACC_data_start): Handle
GOMP_MAP_USE_DEVICE_PTR_IF_PRESENT.
* target.c (gomp_map_vars_async): Likewise.
* testsuite/libgomp.oacc-c-c++-common/host_data-7.c: New.
