This patch enables use of 'declare mapper' for 'target update' directives,
for each of C, C++ and Fortran.
There are some implementation choices here and some
"read-between-the-lines" consequences regarding this functionality,
as follows:
* It is possible to invoke a mapper which contains clause
This patch implements noncontiguous "target update" for Fortran.
The existing middle end/runtime bits relating to C and 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
Following the similar support for C++, 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 by the
previous patch. Some details of parsing necessarily di
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 provides support for the OpenMP 5.0+ array-shaping
operator and for strided/rectangular updates for 'target update'
directives. Each of C, C++ and Fortran is supported (using existing
base language syntax for the last).
This series applies on top of the "infrastructure" support
This patch works around behaviour of the 2D and 3D memcpy operations in
the CUDA driver runtime. Particularly in Fortran, the "base pointer"
of an array (used for either source or destination of a host/device copy)
may lie outside of data that is actually stored on the device. The fix
is to make
