ddb25eb9ca [PR92726, PR92970, PR92984] [OpenACC] Clarify 'acc_delete' etc. for 'NULL'-in, non-present data, or size zero
PR92970 "OpenACC 2.5: 'acc_delete' etc. on non-present data is a no-op" is an
actual bug fix, and the other ones are fall-out, currently undefined behavior.

	PR libgomp/92984
	* oacc-mem.c (delete_copyout): No-op behavior if 'lookup_host'
	fails.

62aee289e4 Add OpenACC 2.6 `serial' construct support
The `serial' construct (cf. section 2.5.3 of the OpenACC 2.6 standard)
    is equivalent to a `parallel' construct with clauses `num_gangs(1)
    num_workers(1) vector_length(1)' implied.
    These clauses are therefore not supported with the `serial'
    construct. All the remaining clauses accepted with `parallel' are also
    accepted with `serial'.

    The `serial' construct is implemented like `parallel', except for
    hardcoding dimensions rather than taking them from the relevant
    clauses, in `expand_omp_target'.

    Separate codes are used to denote the `serial' construct throughout the
    middle end, even though the mapping of `serial' to an equivalent
    `parallel' construct could have been done in the individual language
    frontends. In particular, this allows to distinguish between compute
    constructs in warnings, error messages, dumps etc.

5d183d1740 Warn about inconsistent OpenACC nested reduction clauses
OpenACC (cf. OpenACC 2.7, section 2.9.11. "reduction clause";
	this was first clarified by OpenACC 2.6) requires that, if a
	variable is used in reduction clauses on two nested loops, then
	there must be reduction clauses for that variable on all loops
	that are nested in between the two loops and all these reduction
	clauses must use the same operator.
	This commit introduces a check for that property which reports
	warnings if it is violated.

4a75460b00 [nvptx, libgomp] Fix cuMemAlloc with size zero
Consider test-case:
...
int
main (void)
{
  #pragma acc parallel async
  ;
  #pragma acc parallel async
  ;
  #pragma acc wait

  return 0;
}
...

This fails with:
...
libgomp: cuMemAlloc error: invalid argument
Segmentation fault (core dumped)
...
The cuMemAlloc error is due to the fact that we're try to allocate 0 bytes.

Fix this by preventing calling map_push with size zero argument in nvptx_exec.

This also has the consequence that for the abort-1.c test-case, we end up
calling cuMemFree during map_fini for the struct cuda_map allocated in
map_init, which fails because an abort happened.  Fix this by calling
cuMemFree with CUDA_CALL_NOCHECK in cuda_map_destroy.

4fef8e4d8c [nvptx, libgomp] Fix assert (!s->map->active) in map_fini
There are currently two situations where this assert triggers:
...
libgomp/plugin/plugin-nvptx.c: map_fini: Assertion `!s->map->active' failed.
...

First, in abort-1.c, a parallel region triggering an abort:
...
int
main (void)
{
  #pragma acc parallel
  abort ();

  return 0;
}
...

The abort is detected in nvptx_exec as the CUDA_ERROR_ILLEGAL_INSTRUCTION
return status of the cuStreamSynchronize call after kernel launch, which is
then handled by calling non-returning function GOMP_PLUGIN_fatal.
Consequently, the map_pop in nvptx_exec that in case of cuStreamSynchronize
success would remove or inactive the element added by the map_push earlier in
nvptx_exec, does not trigger.  With the element no longer active, but still
marked active and a member of s->map,  we run into the assert during
GOMP_OFFLOAD_fini_device, which is triggered from atexit handler
gomp_target_fini (which is triggered by the GOMP_PLUGIN_fatal mentioned above
calling exit).

Second, in pr88941.c, an async parallel region without wait:
...
int
main (void)
{
  #pragma acc parallel async
  ;

  /* no #pragma acc wait */
  return 0;
}
...

Because nvptx_exec is handling an async region, it does not call map_pop for
the element added by map_push, but schedules an kernel execution completion
event to call map_pop.  Again, we run into the assert during
GOMP_OFFLOAD_fini_device, which is triggered from atexit handler
gomp_target_fini, but the exit in this case is triggered by returning from main.
So either the kernel is still running, or the kernel has completed but the
corresponding event that is supposed to call map_pop is stuck in the event
queue, waiting for an event_gc.

Fix this by removing the assert, and skipping the freeing of device memory if
the map is still marked active (though in the async case, this is more a
workaround than an fix).

2ee6cb22c1 [nvptx, libgomp] Fix map_push
The map field of a struct ptx_stream is a FIFO.  The FIFO is implemented as a
single linked list, with pop-from-the-front semantics.

The function map_pop pops an element, either by:
- deallocating the element, if there is more than one element
- or marking the element inactive, if there's only one element

The responsibility of map_push is to push an element to the back, as well as
selecting the element to push, by:
- allocating an element, or
- reusing the element at the front if inactive and big enough, or
- dropping the element at the front if inactive and not big enough, and
  allocating one that's big enough

The current implemention gets at least the first and most basic scenario wrong:

> map = cuda_map_create (size);

We create an element, and assign it to map.

> for (t = s->map; t->next != NULL; t = t->next)
>   ;

We determine the last element in the fifo.

> t->next = map;

We append the new element.

> s->map = map;

But here, we throw away the rest of the FIFO, and declare the FIFO to be just
the new element.

This problem causes the test-case asyncwait-1.c to fail intermittently on some
systems.  The pr87835.c test-case added here is a a minimized and modified
version of asyncwait-1.c (avoiding the kernel construct) that is more likely to
fail.

Fix this by rewriting map_pop more robustly, by:
- seperating the function in two phases: select element, push element
- when reusing or dropping an element, making sure that the element is cleanly
  popped from the queue
- rewriting the push element part in such a way that it can handle all cases
  without needing if statements, such that each line is exercised for each of
  the three cases.

9390f91687 [libgomp, testsuite, openacc] Remove -foffload=-w in reduction-[1-5].c
Before the commit "[libgomp, testsuite, openacc] Don't use const int for
dimensions", the "const int" construct was used to set launch dimensions in
reductions-[1-5].c.  In the case of -xc -O0, the const int is implemented as a
variable by the C front-end.  Consequently, the nvptx back-end generated
warnings that vector_length was overridden to be hard-coded, rather than left to
be set at runtime.  The test-cases silenced these warnings by switching off all
warnings in the accelerator compiler using "-foffload=-w".

Given that no warnings occur anymore, remove the "-foffload=-w" setting.

5d0bc70ae4 [libgomp, testsuite, openacc] Don't use const int for dimensions
Const int is handled differently at -O0 for -xc and -xc++, which can cause noise
in testsuite/libgomp.oacc-c-c++-common test-cases (which are both run for c and
c++) if const int is used for launch dimensions.

Fix this by using #defines instead.
