[pstl] Add a __pstl_config_site header to record the CMake configuration This commit adds a __pstl_config_site header that contains the value of macros specified at CMake configuration time. It works similarly to libc++'s __config_site header, except we always include it as a separate file instead of concatenating it to the main configuration header. It is necessary to thread the includes for that header into libc++'s lit configuration, otherwise we'd be requiring an installation step prior to running the test suite. llvm-svn: 368284 GitOrigin-RevId: bf4808439f10d270b34cdb82765b74cecc1be191
Parallel STL is an implementation of the C++ standard library algorithms with support for execution policies, as specified in ISO/IEC 14882:2017 standard, commonly called C++17. The implementation also supports the unsequenced execution policy specified in Parallelism TS version 2 and proposed for the next version of the C++ standard in the C++ working group paper P1001. Parallel STL offers efficient support for both parallel and vectorized execution of algorithms. For sequential execution, it relies on an available implementation of the C++ standard library.
To use Parallel STL, you must have the following software installed:
unseq
and par_unseq
policies only have effect with compilers that support #pragma omp simd
or #pragma simd
