[Vorbis-dev] [RFC PATCH v1 0/3] Introducing ARM SIMD Support

[Viswanath Puttagunta]

Gentlemen!

Am I at the right place? I posted these patches almost a month ago to "
vorbis-dev at xiph.org"

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

I can see that they got posted
http://lists.xiph.org/pipermail/vorbis-dev/2014-September/thread.html

Please advise.

Regards,
