* [OpenMP] Initial implementation of teams distribute code generationCarlo Bertolli2017-10-041-2/+2
| | | | | | | | https://reviews.llvm.org/D38371 This patch implements codegen for the combined 'teams distribute" OpenMP pragma and adds regression tests for all its clauses. llvm-svn: 314905
* [OPENMP] Allow use of declare target directive inside structAlexey Bataev2017-10-031-1/+5
| | | | | | | | | | declaration. Patch allows using of the `#pragma omp declare target`| `#pragma omp end declare target` directives inside the structures if we need to mark as declare target only some static members. llvm-svn: 314833
* [OPENMP] Capture argument of `device` clause for target-basedAlexey Bataev2017-10-021-1/+11
| | | | | | | | | | directives. The argument of the `device` clause in target-based executable directives must be captured to support codegen for the `target` directives with the `depend` clauses. llvm-svn: 314686
* [OPENMP] Fix handling of implicit mapping of array sections.Alexey Bataev2017-09-261-2/+3

* [OPENMP] Generate implicit map|firstprivate clauses for target-basedAlexey Bataev2017-09-261-32/+166
| | | | | | | | | | directives. If the variable is used in the target-based region but is not found in any private|mapping clause, then generate implicit firstprivate|map clauses for these implicitly mapped variables. llvm-svn: 314205
* [OPENMP] Use canonical declarations for redeclarations checks.Alexey Bataev2017-09-211-3/+6
| | | | | | | | | If the captured variable has some redeclarations we may run into the situation where the redeclaration is used instead of the canonical declaration and we may consider this variable as one not captured before. llvm-svn: 313880
* [OpenMP] fix seg-faults printing diagnostics with invalid ordered(n) valuesRachel Craik2017-09-191-5/+11
| | | | | | | | | | | When the value specified for n in ordered(n) is larger than the number of loops a segmentation fault can occur in one of two ways when attempting to print out a diagnostic for an associated depend(sink : vec): 1) The iteration vector vec contains less than n items 2) The iteration vector vec contains a variable that is not a loop control variable This patch addresses both of these issues. Differential Revision: https://reviews.llvm.org/D38049 llvm-svn: 313675
* [OPENMP] Allow all classes as mappable types.Alexey Bataev2017-09-131-44/+0
| | | | | | | According to upcoming OpenMP 5.0 all classes/structs are now considered as mappable, even polymorphic and with static members. llvm-svn: 313141

* [OPENMP] Fix for PR34398: assert with random access iterator if theAlexey Bataev2017-08-311-2/+2
| | | | | | | | | | | | step>1. If the loop is a loot with random access iterators and the iteration construct is represented it += n, then the compiler crashed because of reusing of the same MaterializedTemporaryExpr around N. Patch fixes it by using the expression as written, without any special kind of wrappings. llvm-svn: 312292
* [OPENMP] Capture global variables in all target executable regions.Alexey Bataev2017-08-291-1/+1
| | | | | | | | Capturing of the global variables occurs only in target regions. Patch fixes it and allows capturing of globals in all target executable directives. llvm-svn: 312024

* [OPENMP][DEBUG] Set proper address space info if required by target.Alexey Bataev2017-08-081-0/+33
| | | | | | | | | | | Arguments, passed to the outlined function, must have correct address space info for proper Debug info support. Patch sets global address space for arguments that are mapped and passed by reference. Also, cuda-gdb does not handle reference types correctly, so reference arguments are represented as pointers. llvm-svn: 310387

* [OPENMP] Add restriction for reduction clause in taskloop directives.Alexey Bataev2017-07-111-0/+43
| | | | | | | | Added checks for the reduction clauses in the taskloop directives: 1. Only addressable items must be used in reduction clauses. 2. Reduction clauses cannot be used with nogroup clauses. llvm-svn: 307693
* [OpenMP] Fix mapping of scalars for combined directivesJonas Hahnfeld2017-07-011-3/+26
| | | | | | | | | | | | | | | | Combined directives like 'target parallel' have two captured statements. Sema has to check the right one from the right direction. Previously, Sema::IsOpenMPCapturedByRef would return false for mapped scalars on combined directives. This results in a wrong signature of the outlined function which triggers an assertion: void llvm::CallInst::init(llvm::FunctionType *, llvm::Value *, ArrayRef<llvm::Value *>, ArrayRef<OperandBundleDef>, const llvm::Twine &): Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"' failed. Fixes PR30975 (and PR31985). New function was taken from clang-ykt. Differential Revision: https://reviews.llvm.org/D34888 llvm-svn: 306956
* [OPENMP] Allow 'use_device_ptr' clause in 'target data' alone.Alexey Bataev2017-05-301-23/+20
| | | | | | | | According to OpenMP 5.0 at least one 'map' or 'use_device_ptr' clause must be specified for 'target data' construct. Patch adds support for this feature. llvm-svn: 304216

* [OPENMP] Fix handling of OpenMP code during template instantiation.Alexey Bataev2017-04-261-95/+174
| | | | | | | | | If some function template is instantiated during handling of OpenMP code, currently it may cause crash of compiler because of trying of capturing variables in non-capturing function scopes. Patch fixes this bug. llvm-svn: 301416
* [OPENMP] Move handling of threadprivate vars from the stack, NFC.Alexey Bataev2017-04-261-69/+75
| | | | | | | Threadprivate variables do no need to be handled in the Stack of all directives, moving it out for better performance and memory. llvm-svn: 301410

| | | | | | | | | | omp for https://reviews.llvm.org/D32237 This patch prepares sema with additional fields to support all those composite and combined constructs of OpenMP that include pragma 'distribute' and 'for', such as 'distribute parallel for'. It also extends the regression tests for 'distribute parallel for' and adds a new one. llvm-svn: 300802

| | | | | | | | - also replace direct equality checks against the ConstantEvaluated enumerator with isConstantEvaluted(), in anticipation of adding finer granularity to the various ConstantEvaluated contexts and reinstating certain restrictions on where lambda expressions can occur in C++17. - update the clang tablegen backend that uses these Enumerators, and add the relevant scope where needed. llvm-svn: 299316
* [OpenMP] Generate better diagnostics for cancel and cancellation pointJonas Hahnfeld2017-02-221-14/+20
| | | | | | | | | | | | | | | checkNestingOfRegions uses CancelRegion to determine whether cancel and cancellation point are valid in the given nesting. This leads to unuseful diagnostics if CancelRegion is invalid. The given test case has produced: region cannot be closely nested inside 'parallel' region As a solution, introduce checkCancelRegion and call it first to get the expected error: one of 'for', 'parallel', 'sections' or 'taskgroup' is expected Differential Revision: https://reviews.llvm.org/D30135 llvm-svn: 295808
* [OpenMP] Prepare Sema for initial implementation for pragma 'distribute ↵Carlo Bertolli2017-02-171-0/+32
| | | | | | | | | | | | | | | parallel for' https://reviews.llvm.org/D29922 This patch adds two fields for use in the implementation of 'distribute parallel for': The increment expression for the distribute loop. As the chunk assigned to a team is executed by multiple threads within the 'parallel for' region, the increment expression has to correspond to the value returned by the related runtime call (for_static_init). The upper bound of the innermost loop ('for' in 'distribute parallel for') is not the globalUB expression normally used for pragma 'for' when found in isolation. It is instead the upper bound of the chunk assigned to the team ('distribute' loop). In this way, we prevent teams from executing chunks assigned to other teams. The use of these two fields can be see in a related explanatory patch: https://reviews.llvm.org/D29508 llvm-svn: 295497

| | | | | | | | | | | | | | | This patch adds support for codegen of 'target teams' on the host. This combined directive has two captured statements, one for the 'teams' region, and the other for the 'parallel'. This target teams region is offloaded using the __tgt_target_teams() call.
