Hi Pythraners,
I have been spending the last week working on restoring automatic
vectorization support in Pythran. Some good news:
1. The whole Pythran numpy test suite now compiles fine in SIMD mode.
This is a goal we never reached with the previous SIMD implementation
2. We get decent speedups (see attached files)
way to go!
