I just merged https://github.com/serge-sans-paille/pythran/pull/1008
into master. This replaces boost.simd by xsimd , resulting in better
compilation speed when explicit SIMD is asked for. And you do it by
passing -DUSE_XSIMD instead of -DUSE_BOOST_SIMD.
There's still work to do on xsimd, including profiling and using it in
more places, but that's a great step forward, thanks a lot to @wolfv for
his help on the integration!
