Re: [eigen] alignment c++17

Hi Sylvain,

I still haven't tried this new feature, but in theory I ended up with the same conclusion modulo some adjustments in Eigen code to properly tells the compiler about alignment requirements through the C++ standard. If you've tried and got successful runs without any adjustment, please let us know!

Hi,

Happy new year and best wishes to everybody !

I just took back my old project (C++11) and moved it to C++17.

I understood that C++17 solved the issue with the alignment, am I correct?

Does it mean that:

• I don't need EIGEN_MAKE_ALIGNED_OPERATOR_NEW anymore
  
• I don't need to use template<class T> using aligned_vector = std::vector<T,Eigen::aligned_allocator<T>> but vector<T> will be aligned by default
• eigen objects can be passed by copy to functions, not only by reference ? 

Best regards,

Sylvain
