Re: [RFC PATCH v1 0/3] Introducing ARM SIMD Support

Hello Vorbis Developers / Monty,

Am I at the right place? I posted these patches about 2 weeks ago to "
[email protected]"

I haven't seen any response/reviews about this patch. Neither do I see any
other emails from this mailing list.

Please advise.
