[pstl] Replace direct use of assert() with _PSTL_ASSERT Standard libraries may (libstdc++ in particular) forbid direct use of assert()/<cassert> in library code. Differential Revision: https://reviews.llvm.org/D60249 GitOrigin-RevId: 2e15f4ac572bcf429ec12e8f3efbb8ad254042c7
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
