Following the similar support for C++ and Fortran, here is the
C implementation for the OpenMP 5.0 array-shaping operator, and for
strided and rectangular updates for "target update".
Much of the implementation is shared with the C++ support added earlier
in this patch series. Some details of par
This patch implements noncontiguous "target update" for Fortran.
The existing middle end/runtime bits relating to C++ support are reused,
with some small adjustments, e.g.:
1. The node used to map the OMP "array descriptor" (from omp-low.cc
onwards) now uses the OMP_CLAUSE_SIZE field as a b
At present, map/to/from clauses on OpenMP "target" directives may be
expanded into several mapping nodes if they describe array sections with
pointer or reference bases, or similar. This patch allows the original
clause to be replaced during that expansion, mostly by passing the list
pointer to th
This patch series adds support for the array-shaping operator from OpenMP
5.0, and strided and rectangular transfers for "target update" directives.
The patches were previously posted for mainline here:

This patch fixes "exit data" for (C++) reference-to-pointer struct
components with array sections, such as:
struct S { int *&ptr; [...] };
...
#pragma omp target exit data map(from: str->ptr, str->ptr[0:n])
Such exits need two "detach" operations. We need to unmap
both the pointer and the s
