openmp: Add support for non-constant iterator parameters in map, to and from clauses
This patch enables support for using non-constant expressions when specifying
iterators in the map clause of target constructs and to/from clauses of
target update constructs.
gcc/
* gimplify.cc (omp_iterator_elems_length): New.
(build_omp_iterators_loops): Change type of elements
array to pointer of pointers if array length is non-constant, and
assign size with indirect reference. Reorder elements added to
iterator vector and add element containing the iteration count. Use
omp_iterator_elems_length to compute element array size required.
* gimplify.h (omp_iterator_elems_length): New prototype.
* omp-low.cc (lower_omp_map_iterator_expr): Reorder elements read
from iterator vector. If elements field is a pointer type, assign
using pointer arithmetic followed by indirect reference, and return
the field directly.
(lower_omp_map_iterator_size): Reorder elements read from iterator
vector. If elements field is a pointer type, assign using pointer
arithmetic followed by indirect reference.
(allocate_omp_iterator_elems): New.
(free_omp_iterator_elems): New.
(lower_omp_target): Call allocate_omp_iterator_elems before inserting
loops sequence, and call free_omp_iterator_elems afterwards.
* tree-pretty-print.cc (dump_omp_iterators): Print extra elements in
iterator vector.

output.
