2021-11-30Make OpenACC orphan gang reductions errorsCesar Philippidis1-0/+4
This patch promotes all OpenACC gang reductions on orphan loops as errors. Accord to the spec, orphan loops are those which are not lexically nested inside an OpenACC parallel or kernels regions. I.e., acc loops inside acc routines. At first I thought this could be a warning because the gang reduction finalizer uses an atomic update.

2021-11-12openmp: Honor OpenMP 5.1 num_teams lower boundJakub Jelinek1-6/+36
The following patch implements what I've been talking about earlier, honor that for explicit num_teams clause we create at least the lower-bound (if not specified, upper-bound) teams in the league. For host fallback, it still means we only have one thread doing all the teams, sequentially one after another. For PTX and GCN, I think the new teams-2.c test and maybe teams-4.c too will or might fail. For these offloads, I think it is ok to remove symbols no longer used from libgomp.a. If num_teams_lower is bigger than the provided num_blocks or num_workgroups, we should arrange for gomp_num_teams_var to be num_teams_lower - 1, stop using the %ctaid.x or __builtin_gcn_dim_pos (0) for omp_get_team_num () and instead use for it some .shared var that GOMP_teams4 initializes to %ctaid.x or __builtin_gcn_dim_pos (0) when first and for !first increment that by num_blocks or num_workgroups each time and only return false when we are above num_teams_lower. Any help with actually implementing this for the 2 architectures highly appreciated. 2021-11-12 Jakub Jelinek <jakub@redhat.com> gcc/ * omp-builtins.def (BUILT_IN_GOMP_TEAMS): Remove.

2021-11-11openmp: Add support for 2 argument num_teams clauseJakub Jelinek1-1/+1
In OpenMP 5.1, num_teams clause can accept either one expression as before, but it in that case changed meaning, rather than create <= expression teams it is now create == expression teams. Or it accepts two expressions separated by :, with the meaning that the first is low bound and second upper bound on how many teams should be created. The other ways to set number of teams are upper bounds with lower bound of 1. The following patch does parsing of this for C/C++. For host teams, we actually don't need to do anything further right now, we always create (pretend to create) exactly the requested number of teams, so we can just evaluate and throw away the lower bound for now. For teams nested in target, we don't guarantee that though and further work will be needed. In particular, omplower now turns the teams part of: struct S { S (); S (const S &); ~S (); int s; }; void bar (S &, S &); int baz (); _Pragma ("omp declare target to (baz)"); void foo (void) { S a, b; #pragma omp target private (a) map (b) { #pragma omp teams firstprivate (b) num_teams (baz ()) { bar (a, b); } } } into: retval.0 = baz (); retval.1 = retval.0; { unsigned int retval.3; struct S * D.2549; struct S b; retval.3 = (unsigned int) retval.1; D.2549 = .omp_data_i->b; S::S (&b, D.2549); #pragma omp teams num_teams(retval.1) firstprivate(b) shared(a) __builtin_GOMP_teams (retval.3, 0); { bar (&a, &b); } S::~S (&b); #pragma omp return(nowait) } IMHO we want a new API, say GOMP_teams3 which will take 3 arguments instead of 2 (the lower and upper bounds from num_teams and thread_limit) and will return a bool whether it should do the teams body or not. And, we should add right before outermost {} above while (__builtin_GOMP_teams3 ((unsigned) retval.1, (unsigned) retval.1, 0)) and remove the __builtin_GOMP_teams call. The current function performs exit equivalent (at least on NVPTX) which seems bad because that means the destructors of e.g. private variables on target aren't invoked, and at the current placement neither destructors of the already constructed privatized variables in teams. I'll do this next on the compiler side, but I'm afraid I'll need help with the nvptx and amdgcn implementations. E.g. for nvptx, we won't be able to use %ctaid.x . I think ideal would be to use a .shared integer variable for the omp_get_team_num value, but I don't have any experience with that, are .shared variables zero initialized by default, or do they have random value at start? PTX docs say they aren't initializable. 2021-11-11 Jakub Jelinek <jakub@redhat.com> gcc/ * tree.h (OMP_CLAUSE_NUM_TEAMS_EXPR): Rename to ... (OMP_CLAUSE_NUM_TEAMS_UPPER_EXPR): ... this.

2021-10-11openmp: Add omp_set_num_teams, omp_get_max_teams, omp_[gs]et_teams_thread_limitJakub Jelinek1-1/+5
OpenMP 5.1 adds env vars and functions to set and query new ICVs used as fallback if thread_limit or num_teams clauses aren't specified on teams construct. The following patch implements those, though further work will be needed: 1) OpenMP 5.1 also changed the num_teams clause, so that it can specify both lower and upper limit for how many teams should be created and changed the meaning when only one expression is provided, instead of num_teams(expr) in 5.0 meaning num_teams(1:expr) in 5.1, it now means num_teams(expr:expr), i.e. while previously we could create 1 to expr teams, in 5.1 we have some low limit by default equal to the single expression provided and may not create fewer teams. For host teams (which we don't currently implement efficiently for NUMA hosts) we trivially satisfy it now by always honoring what the user asked for, but for the offloading teams I think we'll need to rethink the APIs; currently teams construct is just a call that returns and possibly lowers the number of teams; and whenever possible we try to evaluate num_teams/thread_limit already on the target construct and the GOMP_teams call just sets the number of teams to the minimum of provided and requested teams; for some cases e.g. where target is not combined with teams and num_teams expression calls some functions etc., we need to call those functions in the target region and so it is late to figure number of teams, but also hw could just limit what it is willing to create; in that case I'm afraid we need to run the target body multiple times and arrange for omp_get_team_num () returning the right values 2) we need to finally implement the NUMA handling for GOMP_teams_reg 3) I now realize I haven't added some testcase coverage, will do that incrementally 4) libgomp.texi needs updates for these new APIs, but also others like the allocator 2021-10-11 Jakub Jelinek <jakub@redhat.com> gcc/ * omp-low.c (omp_runtime_api_call): Handle omp_get_max_teams, omp_[sg]et_teams_thread_limit and omp_set_num_teams. libgomp/ * omp.h.in (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): Declare. * omp_lib.f90.in (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): Declare. * omp_lib.h.in (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): Declare. * libgomp.h (gomp_nteams_var, gomp_teams_thread_limit_var): Declare. * libgomp.map (OMP_5.1): Export omp_get_max_teams{,_}, omp_get_teams_thread_limit{,_}, omp_set_num_teams{,_,_8_} and omp_set_teams_thread_limit{,_,_8_}. * icv.c (omp_set_num_teams, omp_get_max_teams, omp_set_teams_thread_limit, omp_get_teams_thread_limit): New functions. * env.c (gomp_nteams_var, gomp_teams_thread_limit_var): Define.

2021-08-17openmp: Implement OpenMP 5.1 scope constructJakub Jelinek1-13/+168
This patch implements the OpenMP 5.1 scope construct, which is similar to worksharing constructs in many regards, but isn't one of them. The body of the construct is encountered by all threads though, it can be nested in itself or intermixed with taskgroup and worksharing etc. constructs can appear inside of it (but it can't be nested in worksharing etc. constructs). The main purpose of the construct is to allow reductions (normal and task ones) without the need to close the parallel and reopen another one. If it doesn't have task reductions, it can be implemented without any new library support, with nowait it just does the privatizations at the start if any and reductions before the end of the body, with without nowait emits a normal GOMP_barrier{,_cancel} at the end too. For task reductions, we need to ensure only one thread initializes the task reduction library data structures and other threads copy from that, so a new GOMP_scope_start routine is added to the library for that. It acts as if the start of the scope construct is a nowait worksharing construct (that is ok, it can't be nested in other worksharing constructs and all threads need to encounter the start in the same order) which does the task reduction initialization, but as the body can have other scope constructs and/or worksharing constructs, that is all where we use this dummy worksharing construct. With task reductions, the construct must not have nowait and ends with a GOMP_barrier{,_cancel}, followed by task reductions followed by GOMP_workshare_task_reduction_unregister. Only C/C++ FE support is done. 2021-08-17 Jakub Jelinek <jakub@redhat.com> gcc/ * tree.def (OMP_SCOPE): New tree code. * tree.h (OMP_SCOPE_BODY, OMP_SCOPE_CLAUSES): Define. * tree-nested.c (convert_nonlocal_reference_stmt, convert_local_reference_stmt, convert_gimple_call): Handle GIMPLE_OMP_SCOPE. * tree-pretty-print.c (dump_generic_node): Handle OMP_SCOPE. * gimple.def (GIMPLE_OMP_SCOPE): New gimple code. * gimple.c (gimple_build_omp_scope): New function.

2021-08-12openmp: Add support for OpenMP 5.1 masked constructJakub Jelinek1-7/+34
This construct has been introduced as a replacement for master construct, but unlike that construct is slightly more general, has an optional clause which allows to choose which thread will be the one running the region, it can be some other thread than the master (primary) thread with number 0, or it could be no threads or multiple threads (then of course one needs to be careful about data races). It is way too early to deprecate the master construct though, we don't even have OpenMP 5.0 fully implemented, it has been deprecated in 5.1, will be also in 5.2 and removed in 6.0. But even then it will likely be a good idea to just -Wdeprecated warn about it and still accept it. The patch also contains something I should have done much earlier, for clauses that accept some integral expression where we only care about the value, forces during gimplification that value into either a min invariant (as before), SSA_NAME or a fresh temporary, but never e.g. a user VAR_DECL, so that for those clauses we don't need to worry about adjusting it. 2021-08-12 Jakub Jelinek <jakub@redhat.com> gcc/ * tree.def (OMP_MASKED): New tree code. * tree-core.h (enum omp_clause_code): Add OMP_CLAUSE_FILTER. * tree.h (OMP_MASKED_BODY, OMP_MASKED_CLAUSES, OMP_MASKED_COMBINED, OMP_CLAUSE_FILTER_EXPR): Define. * tree.c (omp_clause_num_ops): Add OMP_CLAUSE_FILTER entry.

2021-07-01openmp - Fix up && and || reductions [PR94366]Jakub Jelinek1-31/+24
As the testcase shows, the special treatment of && and || reduction combiners where we expand them as omp_out = (omp_out != 0) && (omp_in != 0) (or with ||) is not needed just for &&/|| on floating point or complex types, but for all &&/|| reductions - when expanded as omp_out = omp_out && omp_in (not in C but GENERIC) it is actually gimplified into NOP_EXPRs to bool from both operands, which turns non-zero values multiple of 2 into 0 rather than 1. This patch just treats all &&/|| the same and furthermore uses bool type instead of int for the comparisons. 2021-07-01 Jakub Jelinek <jakub@redhat.com> PR middle-end/94366 gcc/ * omp-low.c (lower_rec_input_clauses): Rename is_fp_and_or to is_truth_op, set it for TRUTH_*IF_EXPR regardless of new_var's type, use boolean_type_node instead of integer_type_node as NE_EXPR type.

2021-06-24openmp: in_reduction clause support on target constructJakub Jelinek1-20/+183
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). 2021-06-24 Jakub Jelinek <jakub@redhat.com> gcc/ * tree.h (OMP_CLAUSE_MAP_IN_REDUCTION): Document meaning for OpenMP. * gimplify.c (gimplify_scan_omp_clauses): For OpenMP map clauses with OMP_CLAUSE_MAP_IN_REDUCTION flag partially defer gimplification of non-decl OMP_CLAUSE_DECL.

2021-05-26openmp: Fix up handling of target constructs in offloaded routines [PR100573]Jakub Jelinek1-6/+33
OpenMP Nesting of Regions restrictions say: - If a target update, target data, target enter data, or target exit data construct is encountered during execution of a target region, the behavior is unspecified. - If a target construct is encountered during execution of a target region and a device clause in which the ancestor device-modifier appears is not present on the construct, the behavior is unspecified. That wording is about the dynamic (runtime) behavior, not about lexical nesting, so while it is UB if omp target * is encountered in the target region, we need to make it compile and link (for lexical nesting of target * inside of target we actually emit a warning). To make this work, I had to do multiple changes. One was to mark .omp_data_{sizes,kinds}.* variables when static as "omp declare target". Another one was to add stub GOMP_target* entrypoints to nvptx and gcn libgomp.a. The entrypoint functions shouldn't be called or passed in the offload regions, otherwise libgomp: cuLaunchKernel error: too many resources requested for launch was reported; fixed by changing those arguments of calls to GOMP_target_ext to NULL. And we didn't mark the entrypoints "omp target entrypoint" when the caller has been "omp declare target". 2021-05-26 Jakub Jelinek <jakub@redhat.com> PR libgomp/100573 gcc/ * omp-low.c: Include omp-offload.h.

2021-05-21openacc: Add support for gang local storage allocation in shared memory ↵Julian Brown1-6/+119
[PR90115] This patch implements a method to track the "private-ness" of OpenACC variables declared in offload regions in gang-partitioned, worker-partitioned or vector-partitioned modes. Variables declared implicitly in scoped blocks and those declared "private" on enclosing directives (e.g. "acc parallel") are both handled. Variables that are e.g. gang-private can then be adjusted so they reside in GPU shared memory. The reason for doing this is twofold: correct implementation of OpenACC semantics, and optimisation, since shared memory might be faster than the main memory on a GPU. Handling of private variables is intimately tied to the execution model for gangs/workers/vectors implemented by a particular target: for current targets, we use (or on mainline, will soon use) a broadcasting/neutering scheme. That is sufficient for code that e.g. sets a variable in worker-single mode and expects to use the value in worker-partitioned mode. The difficulty (semantics-wise) comes when the user wants to do something like an atomic operation in worker-partitioned mode and expects a worker-single (gang private) variable to be shared across each partitioned worker. Forcing use of shared memory for such variables makes that work properly. In terms of implementation, the parallelism level of a given loop is not fixed until the oaccdevlow pass in the offload compiler, so the patch delays fixing the parallelism level of variables declared on or within such loops until the same point. This is done by adding a new internal UNIQUE function (OACC_PRIVATE) that lists (the address of) each private variable as an argument, and other arguments set so as to be able to determine the correct parallelism level to use for the listed variables. This new internal function fits into the existing scheme for demarcating OpenACC loops, as described in comments in the patch. Two new target hooks are introduced: TARGET_GOACC_ADJUST_PRIVATE_DECL and TARGET_GOACC_EXPAND_VAR_DECL. The first can tweak a variable declaration at oaccdevlow time, and the second at expand time. The first or both of these target hooks can be used by a given offload target, depending on its strategy for implementing private variables. This patch updates the TARGET_GOACC_ADJUST_PRIVATE_DECL target hook in the AMD GCN backend to the current name and prototype.

2021-05-11openmp: Fix up taskloop reduction ICE if taskloop has no iterations [PR100471]Jakub Jelinek1-1/+11
When a taskloop doesn't have any iterations, GOMP_taskloop* takes an early return, doesn't create any tasks and more importantly, doesn't create a taskgroup and doesn't register task reductions. But, the code emitted in the callers assumes task reductions have been registered and performs the reduction handling and task reduction unregistration. The pointer to the task reduction private variables is reused, on input it is the alignment and only on output it is the pointer, so in the case taskloop with no iterations the caller attempts to dereference the alignment value as if it was a pointer and crashes. We could in the early returns register the task reductions only to have them looped over and unregistered in the caller, but I think it is better to tell the caller there is nothing to task reduce and bypass all that. 2021-05-11 Jakub Jelinek <jakub@redhat.com> PR middle-end/100471 * omp-low.c (lower_omp_task_reductions): For OMP_TASKLOOP, if data is 0, bypass the reduction loop including GOMP_taskgroup_reduction_unregister call. * taskloop.c (GOMP_taskloop): If GOMP_TASK_FLAG_REDUCTION and not GOMP_TASK_FLAG_NOGROUP, when doing early return clear the task reduction pointer. * testsuite/libgomp.c/task-reduction-4.c: New test.

Hence, those are also permitted as reduction variable, even though it is not the most sensible thing to do. gcc/c/ChangeLog: * c-typeck.c (c_finish_omp_clauses): Accept float + complex for || and && reductions. gcc/cp/ChangeLog: * semantics.c (finish_omp_reduction_clause): Accept float + complex for || and && reductions. gcc/ChangeLog: * omp-low.c (lower_rec_input_clauses, lower_reduction_clauses): Handle && and || with floating-point and complex arguments. gcc/testsuite/ChangeLog: * gcc.dg/gomp/clause-1.c: Use 'reduction(&:..)' instead of '...(&&:..)'. libgomp/ChangeLog: * testsuite/libgomp.c-c++-common/reduction-1.c: New test. * testsuite/libgomp.c-c++-common/reduction-2.c: New test. * testsuite/libgomp.c-c++-common/reduction-3.c: New test.
2021-05-03[openmp, simt] Disable SIMT for user-defined reductionTom de Vries1-0/+13
The test-case included in this patch contains this target region: ... for (int i0 = 0 ; i0 < N0 ; i0++ ) counter_N0.i += 1; ... When running with nvptx accelerator, the counter variable is expected to be N0 after the region, but instead is N0 / 32. The problem is that rather than getting the result for all warp lanes, we get it for just one lane. This is caused by the implementation of SIMT being incomplete. It handles regular reductions, but appearantly not user-defined reductions. For now, handle this by disabling SIMT in this case, specifically by setting sctx->max_vf to 1.

2021-02-24openmp: Diagnose invalid teams nested in target construct [PR99226]Jakub Jelinek1-0/+24
The OpenMP standard says: "A teams region can only be strictly nested within the implicit parallel region or a target region. If a teams construct is nested within a target construct, that target construct must contain no statements, declarations or directives outside of the teams construct." We weren't diagnosing that restriction, because we need to allow e.g. #pragma omp target {{{{{{ #pragma omp teams ; }}}}}} and as target doesn't need to have teams nested in it, using some special parser of the target body didn't feel right. And after the parsing, the question is if e.g. already parsing of the clauses doesn't add some statements before the teams statement (gimplification certainly will). As we now have a bugreport where we ICE on the invalid code, this just diagnoses a subset of the invalid programs, in particular those where nest to the teams strictly nested in targets the target region contains some other OpenMP construct. 2021-02-24 Jakub Jelinek <jakub@redhat.com> PR fortran/99226 * omp-low.c (struct omp_context): Add teams_nested_p and nonteams_nested_p members.

2020-12-12openmp, openacc: Fix up handling of data regions [PR98183]Jakub Jelinek1-3/+4
While the data regions (target data and OpenACC counterparts) aren't standalone directives, unlike most other OpenMP/OpenACC constructs we allow (apparently as an extension) exceptions and goto out of the block. During gimplification we place an *end* call into a finally block so that it is reached even on exceptions or goto out etc.). During omplower pass we then add paired #pragma omp return for them, but due to the exceptions because the region is not SESE we can end up with #pragma omp return appearing only conditionally in the CFG etc., which the ompexp pass can't handle. For the ompexp pass, we actually don't care about the end part or about target data nesting, so we can treat it as standalone directive. 2020-12-12 Jakub Jelinek <jakub@redhat.com> PR middle-end/98183 * omp-low.c (lower_omp_target): Don't add OMP_RETURN for data regions. * omp-expand.c (expand_omp_target): Don't try to remove OMP_RETURN for data regions.
