[RFC PATCH v1] arm: kf_bfly4: Introduce ARM neon intrinsics
Hello,
This patch introduces ARM NEON Intrinsics to optimize
kf_bfly4 routine in celt part of libopus.
Using NEON optimized kf_bfly4(_neon) routine helped improve
performance of opus_fft_impl function by about 21.4%. The
end use case was decoding a music opus ogg file. The end
use case saw performance improvement of about 4.47%.

[RFC PATCH v1] arm: kf_bfly4: Introduce ARM neon intrinsics
Optimize kf_bfly4 function using ARM NEON intrinsics
for SoCs that have NEON VFP unit
As initial step, only targetting ARMv7-VFP based SoCs.
To enable this optimization, use --enable-armv7-neon-float
when running configure command. This is disabled by default.
