armv7(float): Optimize encode usecase using NE10 library
Optimize opus encode (float only) usecase using ARM NE10
library. Mainly effects opus_fft and ctl_mdct_forward
and related functions.
This optimization can be used for ARM CPUs that have NEON
VFP unit. This patch only enables optimizations for ARMv7.
Official ARM NE10 library page available at
http://projectne10.github.io/Ne10/
To enable this optimization, use
--enable-intrinsics --with-NE10=<install_prefix>
or
--enable-intrinsics --with-NE10-libraries=<NE10_lib_dir> --with-NE10-includes=<NE10_includes_dir>
Compile time checks made during configure process to make sure
optimization option available only when compiler supports NEON
instrinsics.
Runtime checks made to make sure optimized functions only called
on appropriate hardware.
