* [clang][OpenMP] Revert "OMPFlushClause is synthetic, no such clause exists"Roman Lebedev2019-03-061-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This reverts rL352390 / D57280. As discussed in https://reviews.llvm.org/D57112#inline-506781, 'flush' clause does not exist in the OpenMP spec, it can not be specified, and `OMPFlushClause` class is just a helper class. Now, here's the caveat. I have read @ABataev's > Well, I think it would be good to filter out OMPC_flush somehow > because there is no such clause actually, it is a pseudo clause > for better handling of the flush directive. as if that clause is pseudo clause that only exists for the sole purpose of simplifying the parser. As in, it never reaches AST. I did not however try to verify that. Too bad, i was wrong. It absolutely *does* reach AST. Therefore my understanding/justification for the change was flawed, which makes the patch a regression which **must** be reverted. @gribozavr has brought that up again in https://reviews.llvm.org/D57112#inline-521238 > > ... > Sorry to be late for this discussion, but I don't think this conclusion > follows. ASTMatchers are supposed to match the AST as it is. > Even if OMPC_flush is synthetic, it exists in the AST, and users might > want to match it. I think users would find anything else (trying to filter > out AST nodes that are not in the source code) to be surprising.

* [OpenMP 5.0] Parsing/sema support for from clause with mapper modifier.Michael Kruse2019-02-251-2/+18
| | | | | | | | | | | | | | | | | | | | This patch implements the parsing and sema support for the OpenMP 'from'-clause with potential user-defined mappers attached. User-defined mappers are a new feature in OpenMP 5.0. A 'from'-clause can have an explicit or implicit associated mapper, which instructs the compiler to generate and use customized mapping functions. An example is shown below: struct S { int len; int *d; }; #pragma omp declare mapper(id: struct S s) map(s, s.d[0:s.len]) struct S ss; #pragma omp target update from(mapper(id): ss) // use the mapper with name 'id' to map ss from device Contributed-by: Lingda Li <lildmh@gmail.com> Differential Revision: https://reviews.llvm.org/D58638 llvm-svn: 354817

* [OpenMP 5.0] Parsing/sema support for "omp declare mapper" directive.Michael Kruse2019-02-011-0/+11
| | | | | | | | | | | | | | | | | This patch implements parsing and sema for "omp declare mapper" directive. User defined mapper, i.e., declare mapper directive, is a new feature in OpenMP 5.0. It is introduced to extend existing map clauses for the purpose of simplifying the copy of complex data structures between host and device (i.e., deep copy). An example is shown below: struct S { int len; int *d; }; #pragma omp declare mapper(struct S s) map(s, s.d[0:s.len]) // Memory region that d points to is also mapped using this mapper.

* [clang][OpenMP] OMPFlushClause is synthetic, no such clause existsRoman Lebedev2019-01-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: As discussed in https://reviews.llvm.org/D57112#inline-506781, 'flush' clause does not exist in the OpenMP spec, it can not be specified, and `OMPFlushClause` class is just a helper class. Therefore `OPENMP_CLAUSE()` in `clang/Basic/OpenMPKinds.def` should not contain 'flush' "clause". I have simply removed the `OPENMP_CLAUSE(flush, OMPFlushClause)` from `clang/Basic/OpenMPKinds.def`, grepped for `OPENMP_CLAUSE` and added `OPENMP_CLAUSE(flush, OMPFlushClause)` back to the **every** place where `OPENMP_CLAUSE` is defined and `clang/Basic/OpenMPKinds.def` is then included. So as-is, this patch is a NFC. Possibly, some of these `OPENMP_CLAUSE(flush, OMPFlushClause)` should be dropped, i don't really know.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

| | | | | | | | | | | | | | | 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 parallel' on the host. It is also the first combined directive that requires two or more captured statements. Support for this functionality is included in the patch. A combined directive such as 'target parallel' has two captured statements, one for the 'target' and the other for the 'parallel' region. Two captured statements are required because each has different implicit parameters (see SemaOpenMP.cpp). For example, the 'parallel' has 'global_tid' and 'bound_tid' while the 'target' does not. The patch adds support for handling multiple captured statements based on the combined directive. When codegen'ing the 'target parallel' directive, the 'target' outlined function is created using the outer captured statement and the 'parallel' outlined function is created using the inner captured statement.
