Cannot compile speexdsp 1.2rc3 on ARM64
Hi all,
I build successfully with speex-1.2rc2. And with speexdsp 1.2rc3, I
build with i386, X86_64, armv7 and armv7s all passed.
But when I build for ARM64 (for iPhone 6), it failed with:
/Applications/Xcode.app/Contents/Developer/usr/bin/make all-recursive
Making all in libspeexdsp
CC preprocess.lo
CC jitter.lo
CC mdf.lo
CC fftwrap.lo

Cannot compile speexdsp 1.2rc3 on ARM64
Hi I'm new to speex list but joined because I'm needing to port the Neon to
ARM64.
On that function, saturate_32bit_to_16bit(), I noticed the ifdef's are
wrong.
The first version is for normal arm 32 bit arm and should be used for arm32
and thumb2 but not thumb1.
The second version is 32 bit neon and should be #ifdef __ARM_NEON__
I've done a third version which is 64 bit neon. I'm working off an
android ver...

[PATCH 0/5] ARM NEON optimization for samplerate converter
From: Jyri Sarha <jsarha at ti.com>
I optimized Speex resampler for NEON capable ARM CPUs. The first patch
should speed up resampling on any platform that can spare the
increased memory usage. It would be nice to have these merged to the
master branch. Please let me know if there is anything I can do to
help the the merge. The patches have been rebased on top of master
branch in
