683f118439 OpenMP: Move omp requires checks to libgomp
Handle reverse_offload, unified_address, and unified_shared_memory
requirements in libgomp by saving them alongside the offload table.
When the device lto1 runs, it extracts the data for mkoffload. The
latter than passes the value on to GOMP_offload_register_ver.

lto1 (either the host one, with -flto [+ ENABLE_OFFLOADING], or in the
offload-device lto1) also does the the consistency check is done,
erroring out when the 'omp requires' clause use is inconsistent.

For all in-principle supported devices, if a requirement cannot be fulfilled,
the device is excluded from the (supported) devices list. Currently, none of
those requirements are marked as supported for any of the non-host devices.

85d613da34 libgomp: Fix up target-31.c test [PR106045]
The i variable is used inside of the parallel in:
      #pragma omp simd safelen(32) private (v)
      for (i = 0; i < 64; i++)
        {
          v = 3 * i;
          ll[i] = u1 + v * u2[0] + u2[1] + x + y[0] + y[1] + v + h[0] + u3[i];
        }
where i is predetermined linear (so while inside of the body
it is safe, private per SIMD lane var) the final value is written to
the shared variable, and in:
      for (i = 0; i < 64; i++)
        if (ll[i] != u1 + 3 * i * u2[0] + u2[1] + x + y[0] + y[1] + 3 * i + 13 + 14 + i)
          #pragma omp atomic write
            err = 1;
which is a normal loop and so it isn't in any way privatized there.
So we have a data race, fixed by adding private (i) clause to the
parallel.

I assume not just that but libgomp.c-c++-common/get-mapped-ptr-1.c too?

It both needs the same treatment, and in the get-mapped-ptr-1.c
case there is even UB, while the Fortran version was using c_loc (q)
as the host pointer, in C/C++ it was using q which was value of
uninitialized pointer.

1158fe4340 openmp: Conforming device numbers and omp_{initial,invalid}_device
OpenMP 5.2 changed once more what device numbers are allowed.
In 5.1, valid device numbers were [0, omp_get_num_devices()].
5.2 makes also -1 valid (calls it omp_initial_device), which is equivalent
in behavior to omp_get_num_devices() number but has the advantage that it
is a constant.  And it also introduces omp_invalid_device which is
also a constant with implementation defined value < -1.  That value should
act like sNaN, any time any device construct (GOMP_target*) or OpenMP runtime
API routine is asked for such a device, the program is terminated.
And if OMP_TARGET_OFFLOAD=mandatory, all non-conforming device numbers (which
is all but [-1, omp_get_num_devices()] other than omp_invalid_device)
must be treated like omp_invalid_device.

For device constructs, we have a compatibility problem, we've historically
used 2 magic negative values to mean something special.
GOMP_DEVICE_ICV (-1) means device clause wasn't present, pick the
		     omp_get_default_device () number
GOMP_DEVICE_FALLBACK (-2) means the host device (this is used e.g. for
			  #pragma omp target if (cond)
			  where if cond is false, we pass -2
But 5.2 requires that omp_initial_device is -1 (there were discussions
about it, advantage of -1 is that one can say iterate over the
[-1, omp_get_num_devices()-1] range to get all devices starting with
the host/initial one.
And also, if user passes -2, unless it is omp_invalid_device, we need to
treat it like non-conforming with OMP_TARGET_OFFLOAD=mandatory.

So, the patch does on the compiler side some number remapping,
user_device_num >= -2U ? user_device_num - 1 : user_device_num.
This remapping is done at compile time if device clause has constant
argument, otherwise at runtime, and means that for user -1 (omp_initial_device)
we pass -2 to GOMP_* in the runtime library where it treats it like host
fallback, while -2 is remapped to -3 (one of the non-conforming device numbers,
for those it doesn't matter which one is which).
omp_invalid_device is then -4.
For the OpenMP device runtime APIs, no remapping is done.

This patch doesn't deal with the initial default-device-var for
OMP_TARGET_OFFLOAD=mandatory , the spec says that the inital ICV value
for that should in that case depend on whether there are any offloading
devices or not (if not, should be omp_invalid_device), but that means
we can't determine the number of devices lazily (and let libraries have the
possibility to register their offloading data etc.).

I agree and I've actually noticed it too right before committing, but I thought

  -fdiagnostics-format=sarif-file

The patch targets SARIF v2.1.0

This is a JSON-based format suited for capturing the results of static
analysis tools (like GCC's -fanalyzer), but it can also be used for plain
GCC warnings and errors.

SARIF supports per-event metadata in diagnostic paths such as
["acquire", "resource"] and ["release", "lock"] (specifically, the
threadFlowLocation "kinds" property: SARIF v2.1.0 section 3.38.8), so
the patch extends GCC"s diagnostic_event subclass with a "struct meaning"
with similar purpose.  The patch implements this for -fanalyzer so that
the various state-machine-based warnings set these in the SARIF output.

The heart of the implementation is in the new file
diagnostic-format-sarif.cc.  Much of the rest of the patch is interface
classes, isolating the diagnostic subsystem (which has no knowledge of
e.g. tree or langhook) from the "client" code in the compiler proper
cc1 etc).

The patch adds a langhook for specifying the SARIF v2.1.0
"artifact.sourceLanguage" property, based on the list in
SARIF v2.1.0 Appendix J.

The patch adds automated DejaGnu tests to our testsuite via new
scan-sarif-file and scan-sarif-file-not directives (although these
merely use regexps, rather than attempting to use a proper JSON parser).

I've tested the patch by hand using the validator at:
  https://sarifweb.azurewebsites.net/Validation
and the react-based viewer at:
  https://microsoft.github.io/sarif-web-component/
which successfully shows most of the information (although not paths,
and not CWE IDs), and I've fixed all validation errors I've seen (though
bugs no doubt remain).

I've also tested the generated SARIF using the VS Code extension linked
to from the SARIF website; I'm a novice with VS Code, but it seems to be
able to handle my generated SARIF files (e.g. showing the data in the
SARIF tab, and showing squiggly underlines under issues, and when I
click on them, it visualizes the events in the path inline within the
source window).

Has anyone written an Emacs mode for SARIF files? (pretty please)

f38b20d68f openmp: Add support for firstprivate and allocate clauses on scope construct
OpenMP 5.2 adds support for firstprivate and allocate clauses on the scope
construct and this patch adds that support to GCC.
5.2 unfortunately (IMNSHO mistakenly) marked scope construct as worksharing,
which implies that it isn't possible to nest inside of it other scope,
worksharing loop, sections, explicit barriers, single etc. which would
make scope far less useful.  I'm not implementing that part, keeping the
5.1 behavior here, and will file an issue to revert that for OpenMP 6.0.
But, for firstprivate it keeps the restriction that is now implied from
worksharing construct that listed var can't be private in outer context,
where for reduction 5.1 had similar restriction explicit even for scope
and 5.2 has it implicitly through worksharing construct.

42fd2cd932 libgomp: Don't define GOMP_HAVE_EFFICIENT_ALIGNED_ALLOC for _aligned_malloc [PR105745]
since apparently _aligned_malloc requires freeing with _aligned_free and:
 /* Defined if gomp_aligned_alloc doesn't use fallback version
    and free can be used instead of gomp_aligned_free.  */
 #define GOMP_HAVE_EFFICIENT_ALIGNED_ALLOC 1
so the second condition isn't satisfied.  For uses inside of the OpenMP
allocators we can still use _aligned_malloc but we need to call _aligned_free
in gomp_aligned_free.

0ccba4ed85 openmp: Add support for enter clause on declare target
OpenMP 5.1 and earlier had 2 different uses of to clause, one for target
update construct with one semantics, and one for declare target directive
with a different semantics.
Under the hood we were using OMP_CLAUSE_TO_DECLARE to represent the latter.
OpenMP 5.2 renamed the declare target clause to to enter, the old one is
kept as a deprecated alias.

As we are far from having full OpenMP 5.2 support, this patch adds support
for the enter clause (and renames OMP_CLAUSE_TO_DECLARE to OMP_CLAUSE_ENTER
with a flag to tell the spelling of the clause for better diagnostics),
but doesn't deprecate the to clause on declare target just yet (that
should be done as one of the last steps in 5.2 support).

c125f504c4 libgomp: Fix occassional hangs with taskwait nowait depend
Richi reported occassional hangs with taskwait-depend-nowait-1.*
tests and I've finally manged to reproduce.  The problem is if
taskwait depend without nowait is encountered soon after
taskwait depend nowait and the former depends on the latter and there
is no other work to do, the taskwait depend without nowait is put
to sleep, but the empty_task optimization in
gomp_task_run_post_handle_dependers wouldn't wake it up in that
case.  gomp_task_run_post_handle_dependers normally does some wakeups
because it schedules more work (another task), which is not the
case of empty_task, but we need to do the wakeups that would be done
upon task completion so that we awake sleeping threads when the
last child is done.
So, the taskwait-depend-nowait-1.* testcase is fixed with the
else if (__builtin_expect (task->parent_depends_on, 0) part of
the patch.
The new testcase can hang on another problem, if the empty task
is the last task of a taskgroup, we need to use atomic store
like elsewhere to decrease the counter to 0, and wake up taskgroup
end if needed.
Yet another spot which can sleep is normal taskwait (without depend),
but I believe nothing needs to be done for that - in that case we
await solely until the children's queue has no tasks, tasks still
waiting for dependencies aren't accounted in that, but the reason
is that if taskwait should wait for something, there needs to be at least
one active child doing something (in the children queue), which then
possibly awakes some of its siblings when the dependencies are met,
or in the empty task case awakes further dependencies, but in any
case the child that finished is still handled as active child and
will awake taskwait at the end if there is nothing further to
do.
Last sleeping case are barriers, but that is handled by ++ret and
awaking the barrier.

the task only for the purpose of dependency tracking and doesn't actually
schedule it and wait for it when the dependencies are satisfied, instead
makes its dependencies satisfied right away.

49d1a2f913 OpenMP: Handle descriptors in target's firstprivate [PR104949]
For allocatable/pointer arrays, a firstprivate to a device
not only needs to privatize the descriptor but also the actual
data. This is implemented as:
  firstprivate(x) firstprivate(x.data) attach(x [bias: &x.data-&x)
where the address of x in device memory is saved in hostaddrs[i]
by libgomp and the middle end actually passes hostaddrs[i]' to
attach.

As side effect, has_device_addr(array_desc) had to be changed:
before, it was converted to firstprivate in the front end; now
it is handled in omp-low.cc as has_device_addr requires a shallow
firstprivate (not touching the data pointer) while the normal
firstprivate requires (now) a deep firstprivate.

6c420193e8 libgomp: Add new runtime routines omp_target_memcpy_async and omp_target_memcpy_rect_async
This patch adds two new OpenMP runtime routines: omp_target_memcpy_async and
omp_target_memcpy_rect_async. Both functions are introduced in OpenMP 5.1 as
asynchronous variants of omp_target_memcpy and omp_target_memcpy_rect.

In contrast to the synchronous variants, the asynchronous functions have two
additional function parameters to allow the specification of task dependences:

	int depobj_count
	omp_depend_t *depobj_list

	integer(c_int), value :: depobj_count
	integer(omp_depend_kind), optional :: depobj_list(*)

The implementation splits the synchronous functions into two parts: (a) check
and (b) copy. Then (a) is used in the asynchronous functions for the sequential
part, and the actual copy process (b) is executed in a new created task. The
sequential part (a) takes into account the requirements for the return values:

"The routine returns zero if successful. Otherwise, it returns a non-zero
value." (omp_target_memcpy_async, OpenMP 5.1 spec, section 3.8.7)

"An application can determine the number of inclusive dimensions supported by an
implementation by passing NULL pointers (or C_NULL_PTR, for Fortran) for both
dst and src. The routine returns the number of dimensions supported by the
implementation for the specified device numbers. No copy operation is
performed." (omp_target_memcpy_rect_async, OpenMP 5.1 spec, section 3.8.8)

Due to asynchronicity an error is thrown if the asynchronous memcpy is not
successful (in contrast to the synchronous functions which use a return
value unequal to zero).

	* omp-low.cc (omp_runtime_api_call): Added target_memcpy_async and
	target_memcpy_rect_async to omp_runtime_apis array.

2c16eb3157 openmp: Add support for inoutset depend-kind
This patch adds support for inoutset depend-kind in depend
clauses.  It is very similar to the in depend-kind in that
a task with a dependency with that depend-kind is dependent
on all previously created sibling tasks with matching address
unless they have the same depend-kind.
In the in depend-kind case everything is dependent except
for in -> in dependency, for inoutset everything is
dependent except for inoutset -> inoutset dependency.
mutexinoutset is also similar (everything is dependent except
for mutexinoutset -> mutexinoutset dependency), but there is
also the additional restriction that only one task with
mutexinoutset for each address can be scheduled at once (i.e.
mutual exclusitivty).  For now we support mutexinoutset
the same as inout/out, but the inoutset support is full.

In order not to bump the ABI for dependencies each time
(we've bumped it already once, the old ABI supports only
inout/out and in depend-kind, the new ABI supports
inout/out, mutexinoutset, in and depobj), this patch arranges
for inoutset to be at least for the time being always handled
as if it was specified through depobj even when it is not.
So it uses the new ABI for that and inoutset are represented
like depobj - pointer to a pair of pointers where the first one
will be the actual address of the object mentioned in depend
clause and second pointer will be (void *) GOMP_DEPEND_INOUTSET.
