When mapping an allocatable variable (or derived-type component), explicitly
or implicitly, all its allocated allocatable components will automatically be
mapped. The patch implements the target hooks, added for this feature to
omp-low.cc with commit r15-3895-ge4a58b6f28383c.
Namely, there is a check whether there are allocatable components at all:
gfc_omp_deep_mapping_p. Then gfc_omp_deep_mapping_cnt, counting the number
of required mappings; this is a dynamic value as it depends on array
bounds and whether an allocatable is allocated or not.
And, finally, the actual mapping: gfc_omp_deep_mapping.
Polymorphic variables are partially supported: the mapping of the _data
component is fully supported, but only components of the declared type
are processed for additional allocatables. Additionally, _vptr is not
touched. This means that everything needing _vtab information requires
unified shared memory; in particular, _size data is required when
accessing elements of polymorphic arrays.
However, for scalar arrays, accessing components of the declare type
should work just fine.
As polymorphic variables are not (really) supported and OpenMP 6
explicitly disallows them, there is now a warning (-Wopenmp) when
they are encountered. Unlimited polymorphics are rejected (error).
Additionally, PRIVATE and FIRSTPRIVATE are not quite supported for
allocatable components, polymorphic components and as polymorphic
variable. Thus, those are now rejected as well.

This patch fixes an ICE by setting the typespec of a dummy argument
from a global function if known. plus setting the correct flag.
This also removes the corresponding assert. I'm not quite sure

I thought better safe than sorry.

Implement LOCAL and LOCAL_INIT; we locally replace the tree declaration by
a local declaration of the outer variable. The 'local_init' then assigns
the value at the beginning of each loop iteration from the outer
declaration.
Note that the current implementation does not handle LOCAL with types that
have a default initializer and LOCAL/LOCAL_INIT for assumed-shape arrays;
this is diagnosed with a sorry error.

As noted in PR 118965, the initial interop implementation overlooked
the requirement in the OpenMP spec that at least one of the "target"
and "targetsync" modifiers is required in both the interop construct
init clause and the declare variant append_args clause.
Adding the check was fairly straightforward, but it broke about a
gazillion existing test cases. In particular, things like "init (x, y)"
which were previously accepted (and tested for being accepted) aren't
supposed to be allowed by the spec, much less things like "init (target)"
where target was previously interpreted as a variable name instead of a
modifier. Since one of the effects of the change is that at least one
modifier is always required, I found that deleting all the code that was
trying to detect and handle the no-modifier case allowed for better
diagnostics.

This patch handles dumping prototypes for C functions returning
function pointers. For the test case
MODULE test
USE, INTRINSIC :: ISO_C_BINDING
CONTAINS
FUNCTION lookup(idx) BIND(C)
type(C_FUNPTR) :: lookup
integer(C_INT), VALUE :: idx
lookup = C_FUNLOC(x1)
END FUNCTION lookup
subroutine x1()
end subroutine x1
END MODULE test
the prototype is
void (*lookup (int idx)) ();
Regression-tested. Again no test case because I don't know how.

Given the recent PR119406 I've tried to grep for concatenated string
literals without space at the end of one line and at the start of next line,
unless it was obviously intentional.
Furthermore, I've then looked through gcc.pot looking for 2 adjacent spaces
and looking back if that wasn't the case of "something "
" with spaces at both sides".
Here is the result from that.
I think just the c.opt change needs an explanation, the "" in the
description is simply eaten up somewhere during the option processing and
gcc -v --help before this patch was displaying

This patch partially enables use of the OpenMP interop construct by adding
middle end support, mostly in the omplower pass, and in the target-independent
part of the libgomp runtime. It follows up on previous patches for C, C++ and
Fortran front ends support. The full interop feature requires another patch to
enable foreign runtime support in libgomp plugins.

Restrict dependency check of ALLOCATE object to variables in the same
statement, but exclude check of length type parameter that might be
set in the declaration and could lead to a bogus cyclic dependency.
PR fortran/60560
gcc/fortran/ChangeLog:
* expr.cc (gfc_traverse_expr): Do not descend into length type
parameter for negative values of auxiliary parameter f.
* resolve.cc (gfc_find_var_in_expr): New helper function to check
dependence of an expression on given variable.
(resolve_allocate_expr): Use it to determine if array bounds in an
ALLOCATE statement depend explicitly on a variable.

Commit r15-7873 copy-pasted erroneous code containing a non-terminating

with an unhandled case leading to a gcc_unreachable () with suitable input.
