This series contains an updated version of the "3/4" patch from this
series:
https://gcc.gnu.org/pipermail/gcc-patches/2021-February/564711.html
together with bits that undo the reversions in:
https://gcc.gnu.org/pipermail/gcc-patches/2021-February/565093.html
and a new approach to handling components of array sections of derived
types, since those are actually already explicitly disallowed by the spec
(OpenACC 3.0).
(Actually the 1/2 patch is the same as the previously-posted version,
apart from testsuite changes.)
Re-tested with offloading to AMD GCN. Further commentary on individual
patches. OK?
Thanks,
Julian

This patch fixes lowering of derived-type mappings which select elements
of arrays of derived types, and similar. These would previously lead
to ICEs.
With this change, OpenACC directives can pass through constructs that
are no longer recognized by the gimplifier, hence alterations are needed
there also.
OK for mainline?
Thanks,
Julian

* [PATCH 2/2] openacc: Strided array sections and components of derived-type arrays

To: gcc-patches; +Cc: fortran, Jakub Jelinek, Tobias Burnus, Thomas Schwinge
This patch disallows selecting components of array sections in update
directives for OpenACC, as specified in OpenACC 3.0, "2.14.4. Update
Directive", "Restrictions":
"In Fortran, members of variables of derived type may appear, including
a subarray of a member. Members of subarrays of derived type may
not appear."
The diagnostic for attempting to use the same construct on other
directives has also been improved.
OK for mainline?
Thanks,
Julian
gcc/fortran/
* openmp.c (resolve_omp_clauses): Disallow selecting components of
arrays of derived type.

* gfortran.dg/goacc/array-with-dt-2.f90: Remove expected errors.
* gfortran.dg/goacc/array-with-dt-6.f90: New test.

commit 366cf1127a547ff77024a551abb01bb1a6e963cd
Author: Julian Brown <julian@codesourcery.com>
Date: Wed Feb 10 11:18:13 2021 -0800
openacc: Strided array sections and components of derived-type arrays
This patch disallows selecting components of array sections in update
directives for OpenACC, as specified in OpenACC 3.0, "2.14.4. Update
Directive":
In Fortran, members of variables of derived type may appear, including
a subarray of a member. Members of subarrays of derived type may
not appear.
The diagnostic for attempting to use the same construct on other
directives has also been improved.
gcc/fortran/
* openmp.c (resolve_omp_clauses): Disallow selecting components
of arrays of derived type.
gcc/testsuite/
* gfortran.dg/goacc/array-with-dt-2.f90: Remove expected errors.
* gfortran.dg/goacc/array-with-dt-6.f90: New test.
* gfortran.dg/goacc/mapping-tests-2.f90: Update expected error.
* gfortran.dg/goacc/ref_inquiry.f90: Update expected errors.
* gfortran.dg/gomp/ref_inquiry.f90: Likewise.
libgomp/
* testsuite/libgomp.oacc-fortran/array-stride-dt-1.f90: Remove
expected errors.

Subject: [PATCH] 'libgomp.oacc-fortran/derivedtypes-arrays-1.f90' OpenACC
'serial' construct diagnostic for nvptx offloading
Fixup for recent commit d28f3da11d8c0aed9b746689d723022a9b5ec04c "openacc: Fix
lowering for derived-type mappings through array elements". With nvptx
offloading we see the usual:
[...]/libgomp.oacc-fortran/derivedtypes-arrays-1.f90: In function 'MAIN__._omp_fn.0':
[...]/libgomp.oacc-fortran/derivedtypes-arrays-1.f90:90:40: warning: using vector_length (32), ignoring 1
libgomp/
* testsuite/libgomp.oacc-fortran/derivedtypes-arrays-1.f90:
OpenACC 'serial' construct diagnostic for nvptx offloading.
(cherry picked from commit 8bafce1be11a301c2421483736c634b8bf330e69)

I'd pushed the wrong thing to devel/omp/gcc-10 branch, so I've now pushed
"Adjust 'libgomp.oacc-fortran/derivedtypes-arrays-1.f90' for og10" in
commit 4777cf66403e311ff3f00bf3d9a60bd5b546f5ed, see attached.

Subject: [PATCH] Adjust 'libgomp.oacc-fortran/derivedtypes-arrays-1.f90' for
og10
This is a fix-up for og10 commit c89b23b73edeeb7e3d8cbad278e505c2d6d770c4
"'libgomp.oacc-fortran/derivedtypes-arrays-1.f90' OpenACC 'serial' construct
diagnostic for nvptx offloading".
We're missing in og10 a few patches related to diagnostics location
tracking/checking, both compiler-side and testsuite-side.

* testsuite/libgomp.oacc-fortran/derivedtypes-arrays-1.f90: Adjust
for og10.
