* [OPENMP] Change linkage of offloading symbols to support droppingAlexey Bataev2018-07-311-2/+2
| | | | | | | | offload targets. Changed the linkage of omp_offloading.img_start.<triple> and omp_offloading.img_end.<triple> symbols from external to external weak to allow dropping of some targets during linking. llvm-svn: 338413
* The patch adds support for the new map interface between clang and ↵Alexey Bataev2018-07-191-30/+38
| | | | | | | | | | | libomptarget. The changes in the interface are the following: device IDs are now 64-bit integers (as opposed to 32-bit) map flags are 64-bit long (used to be 32-bit) mappings for partially mapped structs are now calculated at compile time and members of partially mapped structs are flagged using the MEMBER_OF field Support for is_device_ptr on struct members was dropped - this functionality is not supported by the OpenMP standard and its implementation is technically infeasible (however, use_device_ptr on struct members works as a non-standard extension of the compiler) llvm-svn: 337468

| | | | | | | | | | | | | | | The num_threads-clause on the combined directive applies to the 'parallel' region of this construct. We modify the NumThreadsClause class to capture the clause expression within the 'target' region. The offload runtime call for 'target parallel' is changed to __tgt_target_teams() with 1 team and the number of threads set by this clause or a default if none.

* [OpenMP] Codegen support for 'target parallel' on the host.Arpith Chacko Jacob2017-01-181-0/+802
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
