[OMPT] Provide initialization for Mac OS X 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
