llvm dev - Jul 2021 - Support of parallel STL and <execution> on clang

Hello,

 

Clang 12 did not contain the <execution> header, for parallel operation.

 

GCC >=9 contain an executon header, which rely on Intel oneTBB library

 

Parallel STL and <execution> is on C++17 standard:

On the gcc mailing list, Intel developer Alexey Kukanov say it proposed to
LLVM also

 

https://gcc.gnu.org/legacy-ml/libstdc++/2017-11/msg00113.html

 

I have two questions:

*	Do you consider support parallel STL on future clang (with Intel
OneTBB, like GCC, or without, like Visual Studio 2019)
*	What about import manually intel onetbb library and use it with
libc++ std::sort or std::for_each (by example)

 

Regards

might be more a question for cfe-dev (but leaving llvm-dev here because the
implementation likely crosses the boundary into runtime libraries, etc)
