6263b656c8 [libgomp, testsuite, nvptx] Fix pr96390.c without CUDA
When running the libgomp testsuite on x86_64 with nvptx accelerator, we run into:
...
XPASS: libgomp.c/../libgomp.c-c++-common/pr96390.c (test for excess errors)
FAIL: libgomp.c/../libgomp.c-c++-common/pr96390.c execution test
...

The problem is that we're expecting the following ptxas error:
...
XFAIL: libgomp.c/../libgomp.c-c++-common/pr96390.c (test for excess errors)
Excess errors:
ptxas /tmp/ccZYDw8N.o, line 90; error   : Call to 'baz' requires call prototype
ptxas /tmp/ccZYDw8N.o, line 90; error   : Unknown symbol 'baz'
...

But it's not triggered because ptxas is not in the path, so nvptx-none-as
defaults to --no-verify.

So instead, we run into the same error at execution time.

Fix this by forcing verification using:
...
/* { dg-additional-options "-foffload=-Wa,--verify" \
     { target offload_target_nvptx } } */
...
such that we run into the xfail in this way instead:
...
XFAIL: libgomp.c/../libgomp.c-c++-common/pr96390.c (test for excess errors)
Excess errors:
nvptx-as: error trying to exec 'ptxas': execvp: No such file or directory
nvptx-as: ptxas returned 255 exit status
...

Tested on x86_64-linux with nvptx accelerator.

bbb7f8604e C, C++, Fortran, OpenMP: Add 'has_device_addr' clause to 'target' construct.
This patch adds the 'has_device_addr' clause to the OpenMP 'target' construct
which was introduced in OpenMP 5.1 (OpenMP API 5.1 specification pp. 197ff):

	has_device_addr(list)

"The has_device_addr clause indicates that its list items already have device
addresses and therefore they may be directly accessed from a target device.
If the device address of a list item is not for the device on which the target
region executes, accessing the list item inside the region results in
unspecified behavior. The list items may include array sections." (p. 200)

"A list item may not be specified in both an is_device_ptr clause and a
has_device_addr clause on the directive." (p. 202)

"A list item that appears in an is_device_ptr or a has_device_addr clause must
not be specified in any data-sharing attribute clause on the same target
construct." (p. 203)

6c0399378e OpenMP 5.0: Remove array section base-pointer mapping semantics and other front-end adjustments
This patch implements three pieces of functionality:

(1) Adjust array section mapping to have standards conforming behavior,
mapping array sections should *NOT* also map the base-pointer:

struct S { int *ptr; ... };
struct S s;

Instead of generating this during gimplify:
                              map(to:*_1 [len: 400]) map(attach:s.ptr [bias: 0])

Now, adjust to:

(i.e. do not map the base-pointer together. The attach operation is still
generated, and if s.ptr is already mapped prior, attachment will happen)

The correct way of achieving the base-pointer-also-mapped behavior would be to
use:

(A small Fortran front-end patch to trans-openmp.c:gfc_trans_omp_array_section
 is also included, which removes generation of a GOMP_MAP_ALWAYS_POINTER for
 array types, which appears incorrect and causes a regression in
 libgomp.fortranlibgomp.fortran/struct-elem-map-1.f90)

(2) Related to the first item above, are fixes in libgomp/target.c to not
overwrite attached pointers when handling device<->host copies, mainly for the
"always" case.

(3) The third is a set of changes to the C/C++ front-ends to extend the allowed
component access syntax in map clauses. These changes are enabled for both
OpenACC and OpenMP.

	* c-parser.c (struct omp_dim): New struct type for use inside

0ab29cf0bb openmp: Improve OpenMP target support for C++ (PR92120)
This patch implements several C++ specific mapping capabilities introduced for
OpenMP 5.0, including implicit mapping of this[:1] for non-static member
functions, zero-length array section mapping of pointer-typed members,
lambda captured variable access in target regions, and use of lambda objects
inside target regions.

Several adjustments to the C/C++ front-ends to allow more member-access syntax
as valid is also included.

fab2f61dc1 vectorizer: Fix up -fsimd-cost-model= handling
>	* testsuite/libgomp.c++/scan-10.C: Add option -fvect-cost-model=cheap.

I don't think this is the right thing to do.
This just means that at some point between 2013 when -fsimd-cost-model has
been introduced and now -fsimd-cost-model= option at least partially stopped
working properly.
As documented, -fsimd-cost-model= overrides the -fvect-cost-model= setting
for OpenMP simd loops (loop->force_vectorize is true) if specified differently
from default.
In tree-vectorizer.h we have:
static inline bool
unlimited_cost_model (loop_p loop)
{
  if (loop != NULL && loop->force_vectorize
      && flag_simd_cost_model != VECT_COST_MODEL_DEFAULT)
    return flag_simd_cost_model == VECT_COST_MODEL_UNLIMITED;
  return (flag_vect_cost_model == VECT_COST_MODEL_UNLIMITED);
}
and use it in various places, but we also just use flag_vect_cost_model
in lots of places (and in one spot use flag_simd_cost_model, not sure if
we are sure it is a force_vectorize loop or what).

So, IMHO we should change the above inline function to
loop_cost_model and let it return the cost model and then just
reimplement unlimited_cost_model as
return loop_cost_model (loop) == VECT_COST_MODEL_UNLIMITED;
and then adjust the direct uses of the flag and revert these changes.

3a2bcffac6 openmp: Add support for OpenMP 5.1 atomics for C++
Besides the C++ FE changes, I've noticed that the C FE didn't reject
  #pragma omp atomic capture compare

7619d33471 openmp: in_reduction clause support on target construct
This patch adds support for in_reduction clause on target construct, though
for now only for synchronous targets (without nowait clause).
The encountering thread in that case runs the target task and blocks until
the target region ends, so it is implemented by remapping it before entering
the target, initializing the private copy if not yet initialized for the
current thread and then using the remapped addresses for the mapping
addresses.
For nowait combined with in_reduction the patch contains a hack where the
nowait clause is ignored.  To implement it correctly, I think we would need
to create a new private variable for the in_reduction and initialize it before
doing the async target and adjust the map addresses to that private variable
and then pass a function pointer to the library routine with code where the callback
would remap the address to the current threads private variable and use in_reduction
combiner to combine the private variable we've created into the thread's copy.
The library would then need to make sure that the routine is called in some thread
participating in the parallel (and not in an unshackeled thread).

GOMP_alloc/GOMP_free, so that the library can fail if it would fall back

8155316c6f c++: local-scope OMP UDR reductions have no template head
This corrects the earlier problems with removing the template header
from local omp reductions.  And it uncovered a latent bug.  When we
tsubst such a decl, we immediately tsubst its body.
cp_check_omp_declare_reduction gets a success return value to gate
that instantiation.

udr-2.C got a further error, as the omp checking machinery doesn't
appear to turn the reduction into an error mark when failing.  I
didn't dig into that further.  udr-3.C appears to have been invalid
and accidentally worked.

0801f41944 c++: Change the default dialect to C++17.
Since GCC 9, C++17 support is no longer experimental.  It was too late
to change the default C++ dialect to C++17 in GCC 10, but I think now
it's time to pull the trigger (C++14 was made the default in GCC 6.1).
We're still missing two C++17 library features, but that shouldn't stop
us.  See
<https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2017>
and
<https://gcc.gnu.org/projects/cxx-status.html#cxx17>
for the C++17 status.

I won't list all C++17 features here, but just a few heads-up:

- trigraphs were removed (hardly anyone cares, unless your keyboard is
  missing the # key),
- operator++(bool) was removed (so some tests now run in C++14 and down
  only),
- the keyword register was removed (some legacy code might trip on
  this),
- noexcept specification is now part of the type system and C++17 does
  not allow dynamic exception specifications anymore (the empty throw
  specification is still available, but it is deprecated),
- the evaluation order rules are different in C++17,
- static constexpr data members are now implicitly inline (which makes
  them definitions),
- C++17 requires guaranteed copy elision, meaning that a copy/move
  constructor call might be elided completely.  That means that if
  something relied on a constructor being instantiated via e.g. copying
  a function parameter, it might now fail.

I'll post an update for cxx-status.html and add a new caveat to changes.html
once this is in.

gcc/ChangeLog:
	* doc/invoke.texi (C Dialect Options): Adjust -std default for C++.
	* doc/standards.texi (C Language): Correct the default dialect.

02f7334ac9 c++: Fix up handling of captured vars in lambdas in OpenMP clauses [PR93931]
Without the parser.c change we were ICEing on the testcase, because while the
uses of the captured vars inside of the constructs were replaced with capture
proxy decls, we didn't do that for decls in OpenMP clauses.

With that fixed, we don't ICE anymore, but the testcase is miscompiled and FAILs
at runtime.  This is because the capture proxy decls have DECL_VALUE_EXPR and
during gimplification we were gimplifying those to their DECL_VALUE_EXPRs.
That is fine for shared vars, but for privatized ones we must not do that.
So that is what the cp-gimplify.c changes do.  Had to add a DECL_CONTEXT check
before calling is_capture_proxy because some VAR_DECLs don't have DECL_CONTEXT
set (yet) and is_capture_proxy relies on that being non-NULL always.
