This series contains several backports from mainline to the og10 branch
concerning character and complex types and mixed derived types and array
accesses in OpenACC directive clauses.
Tested with offloading to AMD GCN. I will apply shortly.
Julian Brown (5):
[og10] openacc: Dereference BT_CLASS data pointers but not BT_DERIVED
pointers
[og10] openacc: Use class_pointer instead of pointer attribute for
class types
[og10] openacc: Character types and mixed arrays/derived type tests
[og10] openacc: Fix lowering for derived-type mappings through array
elements
[og10] openacc: Strided array sections and components of derived-type
arrays
Tobias Burnus (2):
[og10] Fortran: OpenMP/OpenACC diagnose substring rejections better
[og10] Fortran: %re/%im fixes for OpenMP/OpenACC +

The stanza in gfc_trans_omp_clauses that handles derived type members
that are themselves derived type pointers or class pointers now adds
an explicit dereference only for the latter. The former is already
dereferenced transparently in gfc_conv_component_ref.

BT_DERIVED members.

Elsewhere in the Fortran front-end, the class_pointer attribute is
used for BT_CLASS entities instead of the pointer attribute. This patch
follows suit for OpenACC. I couldn't actually come up with a test case
where this makes a difference (i.e., where "class_pointer" and "pointer"
have different values at this point in the code), but this may nonetheless
fix a latent bug.

This patch adds some tests for character types that are components
of derived types used in OpenACC data-movement clauses (some of which
currently fail and are thus XFAILed), and tests (also XFAILed) mixing
arrays and derived types. The XFAILs are addressed by follow-on patches.
Originally a combination of several mainline patches.
