openmp, fortran: Add support for map iterators in OpenMP target construct (Fortran)
This adds support for iterators in map clauses within OpenMP
'target' constructs in Fortran.
Some special handling for struct field maps has been added to libgomp in
order to handle arrays of derived types.
gcc/fortran/
* dump-parse-tree.cc (show_omp_namelist): Add iterator support for
OMP_LIST_MAP.
* match.cc (gfc_free_namelist): Free namespace for OMP_LIST_MAP.
* openmp.cc (gfc_free_omp_clauses): Free namespace in namelist for
OMP_LIST_MAP.
(gfc_match_omp_clauses): Parse 'iterator' modifier for 'map' clause.
(resolve_omp_clauses): Resolve iterators for OMP_LIST_MAP.
* trans-openmp.cc: Include tree-ssa-loop-niter.h.
(gfc_trans_omp_array_section): Add iterator argument. Replace
instances of iterator variables with the initial value when
computing biases.
(gfc_trans_omp_clauses): Handle iterators in OMP_LIST_MAP clauses.
Add expressions to iter_block rather than block. Do not apply
iterators to firstprivate maps. Pass iterator to
gfc_trans_omp_array_section.
gcc/
* gimplify.cc (compute_omp_iterator_count): Account for difference
in loop boundaries in Fortran.
(build_omp_iterator_loop): Change upper boundary condition for
Fortran. Insert block statements into innermost loop.
(remove_unused_omp_iterator_vars): Copy block subblocks of old
iterator to new iterator and remove original.
(contains_vars_1): New.
(contains_vars): New.
(extract_base_bit_offset): Add iterator argument. Remove iterator
variables from base. Do not set variable_offset if the offset
does not contain any remaining variables.
(omp_accumulate_sibling_list): Add iterator argument to
extract_base_bit_offset.
* tree-pretty-print.cc (dump_block_node): Ignore BLOCK_SUBBLOCKS
containing iterator block statements.
gcc/testsuite/
* gfortran.dg/gomp/target-map-iterators-1.f90: New.
* gfortran.dg/gomp/target-map-iterators-2.f90: New.
* gfortran.dg/gomp/target-map-iterators-3.f90: New.
* gfortran.dg/gomp/target-map-iterators-4.f90: New.
libgomp/
* target.c (kind_to_name): Handle GOMP_MAP_STRUCT and
GOMP_MAP_STRUCT_UNORD.
(gomp_add_map): New.
(gomp_merge_iterator_maps): Expand fields of a struct mapping
breadth-first.
* testsuite/libgomp.fortran/target-map-iterators-1.f90: New.
* testsuite/libgomp.fortran/target-map-iterators-2.f90: New.
* testsuite/libgomp.fortran/target-map-iterators-3.f90: New.
