Subject: Add Neon intrinsic vp9_fdct8x8_quant_neon
X-Git-Tag: v1.4.0~222
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9f6eba419a876598aa7edaee9e99610fcbf6362b;p=libvpx

Add Neon intrinsic vp9_fdct8x8_quant_neon

On Nexus 7 speed -5 got ~2%, -6 got ~15%, -7 and -8 got ~30%
increase in perf.

Tested on Nexus 7, built with ndk r10d, gcc 4.9.
