By adding omp_get_initial_device and omp_get_num_devices builtins for
C, C++, and Fortran, the following can be achieved:
* By making them pure, multiple calls can be avoiding in some cases.
* Some comparisons can be optimized at compile time.
omp_get_initial_device will be converted to omp_get_num_devices for
consistency; note that OpenMP 6 also permits omp_initial_device (== -1)
as value.
If GCC has not been configure for offloading, either intrinsic will
leads to 0 - and on the offload side, -1 (= omp_initial_device) is
returned for omp_initial_device.

* f95-lang.cc (ATTR_PURE_NOTHROW_LIST): Define.
* trans-expr.cc (get_builtin_fn): Handle omp_get_num_devices

Tobias had noted that the C front end was not treating C23 constexprs
as constant in the user/condition selector property, which led to
missed opportunities to resolve metadirectives at parse time.
Additionally neither C nor C++ was permitting the expression to have
pointer or floating-point type -- the former being a common idiom in
other C/C++ conditional expressions. By using the existing front-end
hooks for the implicit conversion to bool in conditional expressions,
we also get free support for using a C++ class object that has a bool
conversion operator in the user/condition selector.

This patch adds support for OpenMP 5.0 "declare mapper" functionality
for C++. I've merged it to og13 based on the last version
posted upstream, with some minor changes due to the newly-added
'present' map modifier support. There's also a fix to splay-tree
traversal in gimplify.cc:omp_instantiate_implicit_mappers, and this patch
omits the rearrangement of gimplify.cc:gimplify_{scan,adjust}_omp_clauses
that I separated out into its own patch and applied (to og13) already.

The new testcase included in this patch used to ICE in gcc after
diagnosing the first error, and in g++ it only diagnosed the error in
the first metadirective, ignoring the second one. The solution is to
make error recovery in the C front end more like that in the C++ front
end, and remove the code in both front ends that previously tried to
skip all the way over the following statement (instead of just to the
end of the metadirective pragma) after an error.

* c-parser.cc (c_parser_skip_to_closing_brace): New, copied from
the equivalent function in the C++ front end.

after giving an error that the integer trait property is invalid,
similarly to C++ front end.

With compilation for nvptx enabled, two issues showed up:
(a) "error: 'target' construct with nested 'teams' construct contains
directives outside of the 'teams' construct"
See PR comment 9 why this is difficult to fix.
Solution: Add dg-bogus and accept/expect the error for 'target offload_nvptx'.
(b) The assumptions about the dump for 'target offload_nvptx' were wrong
as the metadirective was already expanded to a OMP_NEXT_VARIANT
construct such that no 'omp metadirective' was left in either case.
Solution: Check that no 'omp metadirective' is left; additionally, expect
either OMP_NEXT_VARIANT (when offload_nvptx is available) or no 'teams'
directive at all (if not).

At tree level, the addr ref is also required for array dummy arguments,
contrary to C; the GOMP_interop calls in modify_call_for_omp_dispatch
were updated accordingly (using build_fold_addr_expr).
As the GOMP_interop calls had no location data associated with them,
the init call happened as soon as executing the previous line of code,
which was confusing; solution: use the location data of the function
call itself.

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.

I ran into this while backporting my declare variant/dispatch/interop
patch f016ee89955ab4da5fe7ef89368e9437bb5ffb13 to the og14 development
branch. In C dialects prior to C23 (the default on mainline),
functions declared "float f()" and "float g(void)" aren't considered
equivalent for the purpose of the C front end code that checks whether
a type of a variant matches the base function after accounting for the
added interop arguments. Using "(void)" instead of "()" works in all
C dialects as well as C++, so do that.
gcc/testsuite/ChangeLog
* c-c++-common/gomp/append-args-interop.c: Fix declaration of base
function to be correct for pre-C23 dialects.

They also FAIL on Linux/x86_64 with -mx32.
The problem is two-fold: restricting a test to target x86_64-*-* is
always wrong: an i?86-*-* compiler can produce 64-bit code with -m64
just as well, so it should always be both.
In addition, the -mx32 failure shows that the test seems to be 64-bit
only.
To fix both issues, this patch uses the new x86 effective-target keyword
and restricts the tests to lp64 instead of ! ia32.
Tested on i386-pc-solaris2.11 and x86_64-pc-linux-gnu.

This patch adds support for the case where #pragma omp declare variant
with append_args is used inside a #pragma omp dispatch interop that
specifies fewer interop args than required by the variant; new interop
objects are implicitly created and then destroyed around the call to the
variant, using the GOMP_interop builtin.

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.

Support for dynamic selectors in "declare variant" was developed in
parallel with support for the adjust_args/append_args clauses and the
dispatch construct; they collided in a bad way. This patch fixes the
"sorry" for calls that need both by removing the adjust_args/append_args
code from gimplify_call_expr and invoking it from the new variant
substitution code instead. It's handled as a tree -> tree transformation
rather than tree -> gimple because eventually this code may end up being
invoked from the front ends instead of the gimplifier (see PR115076).

The following testcase was emitting false positive warning that
the rhs of #pragma omp atomic write was stored but not read,
when the atomic actually does read it. The following patch
fixes that by calling default_function_array_read_conversion
on it, so that it is marked as read as well as converted from
lvalue to rvalue.
Furthermore, the code had
if (code == NOP_EXPR) ... else ... if (code == NOP_EXPR) ...
with none of ... parts changing code, so I've merged the two ifs.

dynamic stack allocation not supported'
In Subversion r217296 (Git commit e2acc079ff125a869159be45371dc0a29b230e92)
"Testsuite alloca fixes for ptx", effective-target 'alloca' was added to mark
up test cases that run into the nvptx back end's non-support of dynamic stack
allocation. (Later, nvptx gained conditional support for that in
commit 3861d362ec7e3c50742fc43833fe9d8674f4070e
"nvptx: PTX 'alloca' for '-mptx=7.3'+, '-march=sm_52'+ [PR65181]", but on the
other hand, in commit f93a612fc4567652b75ffc916d31a446378e6613
"bpf: liberate R9 for general register allocation", the BPF back end joined
"the list of targets that do not support alloca in target-support.exp".
Manually maintaining the list of test cases requiring effective-target 'alloca'
is notoriously hard, gets out of date quickly: new test cases added to the test
suite may need to be analyzed and annotated, and over time annotations also may
need to be removed, in cases where the compiler learns to optimize out
'alloca'/VLA usage, for example. This commit replaces (99 % of) the manual
annotations with an automatic scheme: turn test cases into UNSUPPORTED if
running into 'sorry, unimplemented: dynamic stack allocation not supported'.

This fixes a large number of smaller and larger issues with the append_args
clause to 'declare variant' and adds Fortran support for it; it also contains
a larger number of testcases.
In particular, for Fortran, it also handles passing allocatable, pointer,
optional arguments to an interop dummy argument with or without value
attribute. And it changes the internal representation such that dumping the
tree does not lead to an ICE.

'gcc/tree-pretty-print.cc:dump_omp_clause'
In commit b7e20480630e3eeb9eed8b3941da3b3f0c22c969
"openmp: Relax handling of implicit map vs. existing device mappings",
'OMP_CLAUSE_MAP_RUNTIME_IMPLICIT_P' was added next to 'OMP_CLAUSE_MAP_IMPLICIT'
with comment: "NOTE: this is different than OMP_CLAUSE_MAP_IMPLICIT". However,
dumping it as '[implicit]' doesn't exactly help for telling the two apart; make
that '[runtime_implicit]'. Also, prepend a space character, similar to how
we're doing with other such attributes.

The code and test case previously implemented the OpenMP 5.0 spec,
which said in section 2.3.1:
"For functions within a declare target block, the target trait is added
to the beginning of the set..."
In OpenMP 5.1, this was changed to
"For device routines, the target trait is added to the beginning of
the set..."
In OpenMP 5.2 and TR12, it says:
"For procedures that are determined to be target function variants
by a declare target directive..."
The definition of "device routine" in OpenMP 5.1 is confusing, but
certainly the intent of the later versions of the spec is clear that
it doesn't just apply to functions within a begin declare target/end
declare target block.
The only use of the "omp declare target block" function attribute was
to support the 5.0 language, so it can be removed. This patch changes
the context augmentation to use the "omp declare target" attribute
instead.

This patch reimplements the middle-end support for "declare variant"
and extends the resolution mechanism to also handle metadirectives
(PR112779). It also adds partial support for dynamic selectors
(PR113904) and fixes a selector scoring bug reported as PR114596. I hope
this rewrite also improves the engineering aspect of the code, e.g. more
comments to explain what it is doing.
In most cases, variant constructs can be resolved either in the front
end or during gimplification; if the variant with the highest score
has a static selector, then only that one is emitted. In the case
where it has a dynamic selector, it is resolved into a (possibly nested)
if/then/else construct, testing the run-time predicate for each selector
sorted by decreasing order of score until a static selector is found.
In some cases, notably a variant construct in a "declare simd"
function which may or may not expand into a simd clone, it may not be
possible to score or sort the variants until later in compilation (the
ompdevlow pass). In this case the gimplifier emits a loop containing
a switch statement with the variants in arbitrary order and uses the
OMP_NEXT_VARIANT tree node as a placeholder to control which variant
is tested on each iteration of the loop. It looks something like:
switch_var = OMP_NEXT_VARIANT (0, state);
loop_label:
switch (switch_var)
{
case 1:
if (dynamic_selector_predicate_1)
{
alternative_1;
goto end_label;
}
else
{
switch_var = OMP_NEXT_VARIANT (1, state);
goto loop_label;
}
case 2:
...
}
end_label:
Note that when there are no dynamic selectors, the loop is unnecessary
and only the switch is emitted.
Finally, in the ompdevlow pass, the OMP_NEXT_VARIANT magic cookies are
resolved and replaced with constants. When compiling with -O we can
expect that the loop and switch will be discarded by subsequent
optimizations and replaced with direct jumps between the cases,
eventually arriving at code with similar control flow to the
early-resolution cases.
This approach is somewhat simpler than the one currently used for
handling declare variant in that all possible code paths are already
included in the output of the gimplifier, so it is not necessary to
maintain hidden references or data structures pointing to expansions of
not-yet-resolved variant constructs and special logic for passing them
through LTO (see PR lto/96680).
A possible disadvantage of this expansion strategy is that dead code
for unused variants in the switch can remain when compiling without
-O. If this turns out to be a critical problem (e.g., an unused case
includes calls to functions not available to the linker) perhaps some
further processing could be performed by default after ompdevlow to
simplify such constructs.
In order to make this patch more readable for review purposes, it
leaves the existing code for "declare variant" resolution (including
the above-mentioned LTO hack) in place, in some cases just ifdef-ing
out functions that won't compile due to changed interfaces for
dependencies. The next patch in the series will delete all the
now-unused code.

Add the append_args clause of 'declare variant' to C and C++,
fix/improve diagnostic for 'interop' clause and 'declare_variant'
clauses on the way.
Cleanup dispatch handling in gimplify_call_expr a bit and
partially handle 'append_args'. (Namely, those parts that
do not require libraries calls, i.e. a dispatch construct
where the 'device' and 'interop' clause has been specified.)
The sorry can be removed once an enum value like
omp_ipr_(ompx_gnu_)omp_device_num (cf. OpenMP Spec Issue 4451)
has to be added to the runtime side such that omp_get_interop_int
returns the device number of an interop object (as passed to
dispatch via the interop clause); and a call to GOMP_interop
has to be added to create interop objects. Once available, only
a very localized change in gimplify_call_expr is required to
claim for full support. - And Fortran parsing support.

The 'has_device_addr' of 'dispatch' has to be seen in conjunction with the
'need_device_addr' modifier to the 'adjust_args' clause of 'declare variant'.
As the latter has not yet been implemented, 'has_device_addr' has no real
effect. However, to prepare for 'need_device_addr' and as service to the user:
For C, where 'need_device_addr' is not permitted (contrary to C++ and Fortran),
a note is output when then the user tries to use it (alongside the existing
error that either 'nothing' or 'need_device_ptr' was expected).
And, on the ME side, is is lightly handled by diagnosing when - for the
same argument - there is a mismatch between the variant's adjust_args
'need_device_ptr' modifier and dispatch having an 'has_device_addr' clause
(or likewise for need_device_addr with is_device_ptr) as, according to the
spec, those are completely separate.
Thus, 'dispatch' will still do the host to device pointer conversion for
a 'need_device_ptr' argument, even if it appeared in a 'has_device_addr'
clause.
gcc/c/ChangeLog:
* c-parser.cc (OMP_DISPATCH_CLAUSE_MASK): Add has_device_addr clause.

Fixed a check to permit [[omp::decl(allocate,...)]] parsing in C.
Additionaly, we discussed that 'allocate align' should not affect
'alignof' to avoid issues like with:
int a;
_Alignas(_Alignof(a)) int b;
#pragma omp allocate(a) align(128)
_Alignas(_Alignof(a)) int c;
Thus, the alignment is no longer set in the C and Fortran front ends,
but for static variables now in varpool_node::finalize_decl.
(For stack variables, the alignment is handled in gimplify_bind_expr.)
NOTE: 'omp allocate' is not yet supported in C++.

Add middle end support for the 'interop' directive and the 'init', 'use',
and 'destroy' clauses - but fail with a sorry, unimplemented in gimplify.cc.
For Fortran, generate the tree code, update the internal representation,
add some more diagnostic checks and update for newer specification changes
('fr' only takes a single value, but it integer expressions are permitted
again [like with the old syntax] not only constant identifiers).
For C and C++, this patch adds the full parser support for 'interop'.
Still missing is actually handling the directive in the middle end and

For the 'allocate' directive, remove the sorry for static variables and
just keep using normal memory, but honor the requested alignment and set
a DECL_ATTRIBUTE in case a target may want to make use of this later on.
The documentation is updated accordingly.
The C diagnostic to check for predefined allocators (req. for static vars)
failed to accept GCC's ompx_gnu_... allocator, now fixed. (Fortran was
already okay; but both now use new common #defined value for checking.)
And while Fortran common block variables are still rejected, the check
has been improved as before the sorry diagnostic did not work for
common blocks in modules.
Finally, for 'allocate' clause on the target/task/taskloop directives,
there is now a warning for omp_thread_mem_alloc (i.e. predefined allocator
with access = thread), which is undefined behavior according to the
OpenMP specification.
And, last, testing showed that var decl + static_assert sets TREE_USED
but does not produce a statement list in C, which did run into an assert
in gimplify. This special case is now also handled.
gcc/c/ChangeLog:
* c-parser.cc (c_parser_omp_allocate): Set alignment for alignof;
accept static variables and fix predef allocator check.
gcc/fortran/ChangeLog:
* openmp.cc (is_predefined_allocator): Use gomp-constants.h consts.

GOMP_OMPX_PREDEF_ALLOC_MIN, GOMP_OMPX_PREDEF_ALLOC_MAX,

libgomp/ChangeLog:
* allocator.c: Add static asserts for news
GOMP_OMP{,X}_PREDEF_ALLOC_{MIN,MAX} range values.

The testcase decare-variant-duplicates.c added in commit
96246bff0bcd9e5cdec9e6cf811ee3db4997f6d4 failed on 32-bit x86
because on that target "i386" is defined as a preprocessor macro
and cannot be used as an identifier. Fixed by rewriting that test
not to do that.
gcc/testsuite/ChangeLog
* c-c++-common/gomp/declare-variant-duplicates.c: Avoid using
"i386" as an identifier.

TR13 (pre-6.0) of the OpenMP spec says:
"Each trait-property may only be specified once in a trait selector
other than those in the construct selector set."
and
"If trait-property any is specified in the kind trait-selector of the
device selector set or the target_device selector sets, no other
trait-property may be specified in the same selector set."
These restrictions (with slightly different wording) date back to
OpenMP 5.1, but were not in 5.0 which was the basis for GCC's
implementation.
This patch adds a diagnostic, adds new testcases, and fixes some older
testcases that include now-invalid selectors.
gcc/ChangeLog
* omp-general.cc (omp_check_context_selector): Reject other
properties in the same selector set with kind(any). Also reject
duplicate name-list properties.

'self_maps' implies 'unified_shared_memory', except that the latter

self_maps does not. In GCC, currently, both are handled identical.

Several C++ tests fail with --disable-hosted-libstdcxx, whether
because stdc++exp gets linked in despite not being built, because
standard headers are included but that are unavailable in this mode,
or because headers are (mistakenly?) expected to introduce
declarations such as for abort, malloc, etc, but in this mode they
don't.
This patch introduces an effective target for GCC test, equivalent to
one that's available in the libstdc++-v3 testsuite, and arranges for
all such tests to be skipped when libstdc++-v3 is not hosted.

The following patch simplifies c_parser_omp_tile_sizes to use
c_parser_expr_list, so that it will get CPP_EMBED parsing naturally,
without having another spot that needs to be adjusted for it.

Only the 5.1/5.2 tile/unroll constructs are supported, in various
places some preparations for the other 6.0 loop transformations
constructs (interchange/reverse/fuse) are done, but certainly
not complete and not everywhere. The important difference is that
because tile/unroll partial map 1:1 the original loops to generated
canonical loops and add another set of generated loops without canonical
form inside of it, the tile/unroll partial constructs are terminal
for the generated loop, one can't have some loops from the tile or
unroll partial and some further loops from inside the body of that
construct.
The GENERIC representation attempts to match what the standard specifies,
so there are separate OMP_TILE and OMP_UNROLL trees. If for a particular
loop in a loop nest of some OpenMP loop it awaits a generated loop from a
nested loop, or if in OMP_LOOPXFORM_LOWERED OMP_TILE/UNROLL construct
a generated loop has been moved to some surrounding construct, that
particular loop is represented by all NULL_TREEs in the
OMP_FOR_{INIT,COND,INCR,ORIG_DECLS} vector.
The lowering of the loop transforming constructs is done at gimplification
time, at the start of gimplify_omp_for.
I think this way it is more maintainable over magic clauses with various
loop depths on the other looping constructs or the magic OMP_LOOP_TRANS
construct.
Though, I admit I'm still undecided how to represent the OpenMP 6.0
loop transformation case of say:
#pragma omp for collapse (4)
for (int i = 0; i < 32; ++i)
#pragma omp interchange permutation (2, 1)
#pragma omp reverse
for (int j = 0; j < 32; ++j)
#pragma omp reverse
for (int k = 0; k < 32; ++k)
for (int l = 0; l < 32; ++l)
;
Surely the i loop would go to first vector elements of OMP_FOR_*
of the work-sharing loop, then 2 loops are expecting generated loops
from interchange which would be inside of the body. But the innermost
l loop isn't part of the interchange, so the question is where to
put it. One possibility is to have it in the 4th loop of the OMP_FOR,
another possibility would be to add some artificial construct inside
of the OMP_INTERCHANGE and 2 OMP_REVERSE bodies which would contain
the inner loop(s), e.g. it could be OMP_INTERCHANGE without permutation
clause or some artificial ones or whatever.
I've recently raised various unclear things in the 5.1/5.2/TRs versions
regarding loop transformations, in particular
https://github.com/OpenMP/spec/issues/3908
https://github.com/OpenMP/spec/issues/3909
(sorry, private links unless you have OpenMP membership). Until those
are resolved, I have a sorry on trying to mix generated loops with
non-rectangular loops (way too many questions need to be answered before
that can be done) and similarly for mixing non-perfectly nested loops
with generated loops (again, it can be implemented somehow, but is way
too unclear). The second issue is mostly about data sharing, which is
ambiguous, the patch makes the artificial iterators of the loops effectively
private in the associated constructs (more like local), but for user
iterators doesn't do anything in particular, so for now one needs to use
explicit data sharing clauses on the non-loop transformation OpenMP looping
constructs or surrounding parallel/task/target etc.

I've noticed that while we diagnose many other OpenMP exclusive clauses,
we don't diagnose grainsize together with num_tasks on taskloop construct
in all of C, C++ and Fortran (the implementation simply ignored grainsize
in that case) and for Fortran also don't diagnose mixing nogroup clause
with reduction clause(s).
Fixed thusly.
