* [OMPT] Second chunk of final OMPT 5.0 interface updatesJoachim Protze2019-01-153-5/+5
| | | | | | | | | | | | | | | | | | | | | The omp-tools.h file is generated from the OpenMP spec to ensure that the interface is implemented as specified. The other changes are necessary to update the interface implementation to the final version as published in 5.0. The omp-tools.h header was previously called ompt.h, currently a copy under this name is installed for legacy tools.

* [OMPT] Update types according to TR7Joachim Protze2018-09-101-1/+1
| | | | | | | | | | | | | | | | | | Some types and callback signatures have changed from TR6 to TR7. Major changes (only adding signatures and stubs): (-remove idle callback) done by D48362 -add reduction and dispatch callback -add get_task_memory and finalize_tool runtime entry points -ompt_invoker_t becomes ompt_parallel_flag_t -more types of sync_regions Patch provided by Simon Convent Reviewers: hbae, protze.joachim Differential Revision: https://reviews.llvm.org/D50774 llvm-svn: 341834
* Dropped non-supoorted "--no-as-needed" flag from OMPT tests for macOSJoachim Protze2018-07-052-4/+4
| | | | | | | | | | | | | | | | | The flag "--no-as-needed" is not recognized by the linker on macOS making the following tests fail: ompt/loadtool/tool_available/tool_available.c ompt/loadtool/tool_not_available/tool_not_available.c This patch removes this flag for macOS and adds it only for Linux and Windows. I tested it on Ubuntu 16.04 and macOS HighSierra, with Clang/LLVM 6.0.1 and OpenMP trunk. This solution was also discussed in the OpenMP-dev mailing list.

* [OMPT] Add tool_available_search testcaseJoachim Protze2018-02-081-0/+104
| | | | | | | | | | | | | | | | | | Tests the search for tools as defined in the spec. The OMP_TOOL_LIBRARIES environment variable contains paths to the following files(in that order) -to a nonexisting file -to a shared library that does not have a ompt_start_tool function -to a shared library that has an ompt_start_tool implementation returning NULL -to a shared library that has an ompt_start_tool implementation returning a pointer to a valid instance of ompt_start_tool_result_t The expected result is that the last tool gets active and can print in the thread-begin callback.

* [OMPT] Add tool_not_available testcaseJoachim Protze2018-02-082-0/+69
| | | | | | | | | | | | Add a testcase that checks wheter the runtime can handle an ompt_start_tool method that returns NULL indicating that no tool shall be loaded. All tool_available testcases need a separate folder to avoid file conflicts for the generated tools. Differential Revision: https://reviews.llvm.org/D41904 llvm-svn: 324587
* [OMPT] Fix failing test cases for gcc on UbuntuJoachim Protze2017-12-221-2/+2
| | | | | | | | | | | | | | The compiler warns that _BSD_SOURCE is deprecated and _DEFAULT_SOURCE should be used instead. We keep _BSD_SOURCE for older compilers, that don't know about _DEFAULT_SOURCE. The linker drops the tool when linking, since there is no visible need for the library. So we need to tell the linker, that the tool should be linked anyway. Differential Revision: https://reviews.llvm.org/D41499 llvm-svn: 321362
* [CMake] Refactor testing infrastructureJonas Hahnfeld2017-11-291-1/+1
| | | | | | | | | | | | | | | The code for the two OpenMP runtime libraries was very similar. Move to common CMake file that is included and provides a simple interface for adding testsuites. Also add a common check-openmp target that runs all testsuites that have been registered. Note that this renames all test options to the common OPENMP namespace, for example OPENMP_TEST_C_COMPILER instead of LIBOMP_TEST_COMPILER and so on.

* [OMPT] Provide initialization for Mac OS XJonas Hahnfeld2017-11-111-8/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally, the library had a weak symbol for ompt_start_tool() that served as fallback and disabled OMPT if called. Tools could provide their own version and replace the default implementation to register callbacks and lookup functions. This mechanism has worked reasonably well on Linux systems where this interface was initially developed. On Darwin / Mac OS X the situation is a bit more complicated and the weak symbol doesn't work out-of-the-box. In my tests, the library with the tool needed to link against the OpenMP runtime to make the process work. This would effectively mean that a tool needed to choose a runtime library whereas one design goal of the interface was to allow tools that are agnostic of the runtime. The solution is to use dlsym() with the argument RTLD_DEFAULT so that static implementations of ompt_start_tool() are found in the main executable. This works because the linker on Mac OS X includes all symbols of an executable in the global symbol table by default. To use the same code path on Linux, the application would need to be built with -Wl,--export-dynamic. To avoid this restriction, we continue to use weak symbols on Linux systems as before. Finally this patch extends the existing test to cover all possible ways of initializing the tool as described by the standard. It also fixes ompt_finalize() to not call omp_get_thread_num() when the library is shut down which resulted in hangs on Darwin. The changes have been tested on Linux to make sure that it passes the current tests as well as the newly extended one. Differential Revision: https://reviews.llvm.org/D39801 llvm-svn: 317980

* Update implementation of OMPT to the specification OpenMP 5.0 Preview 1 (TR4).Joachim Protze2017-11-011-0/+59
The code is tested to work with latest clang, GNU and Intel compiler. The implementation is optimized for low overhead when no tool is attached shifting the cost to execution with tool attached.
