Yes, I started syrah (https://github.com/boulos/syrah) in 2009 precisely because I loved the masking of LRBni and wanted to "use it" even from SSE, AVX and (later) AVX2. Once I played with NEON though, I realized I had screwed up the format for it.

Sadly, (because KNL doesn't have nearly the same volume) until Skylake became a real thing, I had no reason to update this. I'm planning on dusting it off now!
