Fortran/OpenMP: Fix mapping of array descriptors and deferred-length strings
Previously, array descriptors might have been mapped as 'alloc'
instead of 'to' for 'alloc', not updating the array bounds. The
'alloc' could also appear for 'data exit', failing with a libgomp
assert. In some cases, either array descriptors or deferred-length
string's length variable was not mapped. And, finally, some offset
calculations with array-sections mappings went wrong.
Additionally, the patch now unmaps for scalar allocatables/pointers
the GOMP_MAP_POINTER, avoiding stale mappings.
The testcases contain some comment-out tests which require follow-up
work and for which PR exist. Those mostly relate to deferred-length
strings which have several issues beyong OpenMP support.
gcc/fortran/ChangeLog:
* trans-decl.cc (gfc_get_symbol_decl): Add attributes
such as 'declare target' also to hidden artificial
variable for deferred-length character variables.
* trans-openmp.cc (gfc_trans_omp_array_section,
gfc_trans_omp_clauses, gfc_trans_omp_target_exit_data):
Improve mapping of array descriptors and deferred-length
string variables.
gcc/ChangeLog:
* gimplify.cc (gimplify_scan_omp_clauses): Remove Fortran
special case.
libgomp/ChangeLog:
* testsuite/libgomp.fortran/target-enter-data-3.f90: Uncomment
'target exit data'.
* testsuite/libgomp.fortran/target-enter-data-4.f90: New test.
* testsuite/libgomp.fortran/target-enter-data-5.f90: New test.
* testsuite/libgomp.fortran/target-enter-data-6.f90: New test.
* testsuite/libgomp.fortran/target-enter-data-7.f90: New test.
gcc/testsuite/
* gfortran.dg/goacc/finalize-1.f: Update dg-tree; shows a fix
for 'finalize' as a ptr is now 'delete' instead of 'release'.
* gfortran.dg/gomp/pr78260-2.f90: Likewise as elem-size calc moved
to if (allocated) block
* gfortran.dg/gomp/target-exit-data.f90: Likewise as a var is now a
replaced by a MEM< _25 > expression.
* gfortran.dg/gomp/map-9.f90: Update dg-scan-tree-dump.
* gfortran.dg/gomp/map-10.f90: New test.
