silk_warped_autocorrelation_FIX() NEON optimization
Hi all,
I'm sending patch "Optimize silk_warped_autocorrelation_FIX() for ARM NEON" in an separate email.
It is based on Tim’s aarch64v8 branch https://git.xiph.org/?p=users/tterribe/opus.git;a=shortlog;h=refs/heads/aarch64v8
Thanks for your comments.

[PATCH 9/9] Optimize silk_inner_prod_aligned_scale() for ARM NEON
...function.
How are you building/running these tests? None of the tests (from any of
the patches starting with the second) build for me on 32-bit ARMv7 with
--enable-fixed-point, or even on x86. Example errors:
CCLD tests/test_unit_optimization
tests/test_unit_optimization.o: In function `test_fir':
/home/derf/src/xiph/git/xiph/opus/build/../celt/tests/test_unit_optimization_lpc.c:58:

[PATCH 9/9] Optimize silk_inner_prod_aligned_scale() for ARM NEON
Created corresponding unit test, and the optimization is bit exact with C
function.

ARM NEON optimization -- celt_fir()
Hi all,
This is Linfeng Zhang from Google. I'll work on ARM NEON optimization in the
next few months.
I'm submitting 2 patches in the following couple of emails, which have the new
created celt_fir_neon().
I revised celt_fir_c() to not pass in argument "mem" in Patch 1. If there are
concerns to this change, please let me know.
Many thanks to your comments.

Several patches of ARM NEON optimization
I rebased my previous 3 patches to the current master with minor changes.
Patches 1 to 3 replace all my previous submitted patches.
Patches 4 and 5 are new.
Thanks,
Linfeng Zhang
