Reduce number of enum values passed to libgomp as
GOMP_MAP_PRESENT_{TO,TOFROM,FROM,ALLOC} have the same semantic as
GOMP_MAP_FORCE_PRESENT (i.e. abort if not present, otherwise ignore);
that's different to GOMP_MAP_ALWAYS_PRESENT_{TO,TOFROM,FROM} which also
abort if not present but copy data when present. This is is a follow-up to
the commit r14-1579-g4ede915d5dde93 done 6 days ago.
Additionally, the commit improves a libgomp run-time and a C/C++ compile-time
error wording and extends testcases a tiny bit.
gcc/c/ChangeLog:
* c-parser.cc (c_parser_omp_clause_map): Reword error message for
clearness especially with 'omp target (enter/exit) data.'
gcc/cp/ChangeLog:
* parser.cc (cp_parser_omp_clause_map): Reword error message for
clearness especially with 'omp target (enter/exit) data.'
* semantics.cc (handle_omp_array_sections): Handle
GOMP_MAP_{ALWAYS_,}PRESENT_{TO,TOFROM,FROM,ALLOC} enum values.
gcc/ChangeLog:
* gimplify.cc (gimplify_adjust_omp_clauses_1): Use
GOMP_MAP_FORCE_PRESENT for 'present alloc' implicit mapping.
(gimplify_adjust_omp_clauses): Change
GOMP_MAP_PRESENT_{TO,TOFROM,FROM,ALLOC} to the equivalent
GOMP_MAP_FORCE_PRESENT.
* omp-low.cc (lower_omp_target): Remove handling of no-longer valid
GOMP_MAP_PRESENT_{TO,TOFROM,FROM,ALLOC}; update map kinds used for
to/from clauses with present modifier.
include/ChangeLog:
* gomp-constants.h (enum gomp_map_kind): Change the enum values
GOMP_MAP_PRESENT_{TO,TOFROM,FROM,ALLOC} to be compiler only.
(GOMP_MAP_PRESENT_P): Update to include also GOMP_MAP_FORCE_PRESENT.
libgomp/ChangeLog:
* target.c (gomp_to_device_kind_p, gomp_map_vars_internal): Replace
GOMP_MAP_PRESENT_{FROM,TO,TOFROM,ACLLOC} by GOMP_MAP_FORCE_PRESENT.
(gomp_map_vars_internal, gomp_update): Likewise; unify and improve
error message.
* testsuite/libgomp.c-c++-common/target-present-2.c: Update for
changed error message.
* testsuite/libgomp.fortran/target-present-1.f90: Likewise.
* testsuite/libgomp.fortran/target-present-2.f90: Likewise.
* testsuite/libgomp.oacc-c-c++-common/present-1.c: Likewise.
* testsuite/libgomp.c-c++-common/target-present-1.c: Likewise and
extend testcase to check that data is copied when needed.
* testsuite/libgomp.c-c++-common/target-present-3.c: Likewise.
* testsuite/libgomp.fortran/target-present-3.f90: Likewise.
gcc/testsuite/ChangeLog:
* c-c++-common/gomp/defaultmap-4.c: Update scan-tree-dump.
* c-c++-common/gomp/map-9.c: Likewise.
* gfortran.dg/gomp/defaultmap-8.f90: Likewise.
* gfortran.dg/gomp/map-11.f90: Likewise.
* gfortran.dg/gomp/target-update-1.f90: Likewise.
* gfortran.dg/gomp/map-12.f90: Likewise; also check original dump.
* c-c++-common/gomp/map-6.c: Update dg-error and also check
clause error with 'target (enter/exit) data'.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
