[pstl] Properly extract the version number from pstl_config.h Previously, we'd be performing math on `#define PSTL_VERSION NNN` instead of just `NNN`. It seems like older CMakes didn't complain, but newer CMakes do complain because it doesn't make sense. llvm-svn: 355918 GitOrigin-RevId: 0f4ce2b0d748a0503d6dbadbc44486dda4b5df8e
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
