[Aarch64 v2 00/18] Patches to enable Aarch64 (version 2)
As promised, here's a re-send of all my Aarch64 patches, following
comments by John Ridges.
Note that they actually affect more than just Aarch64 -- other than
the ones specifically guarded by AARCH64_NEON defines, the Neon
intrinsics all also apply on armv7; and the OPUS_FAST_INT64 patches
apply on any 64-bit machine.
The patches should largely be independent and independently useful,

[AArch64 neon intrinsics v4 0/5] Rework Neon intrinsic code for Aarch64 patchset
Following Tim's comments, here are my reworked patches for the Neon intrinsic function patches of
of my Aarch64 patchset, i.e. replacing patches 5-8 of the v2 series. Patches 1-4 and 9-18 of the
old series still apply unmodified.
The one new (as opposed to changed) patch is the first one in this series, to add named constants
for the ARM architecture variants.
There are also some minor code

[PATCH 0/8] Patches for arm64 (aarch64) support
This sequence of patches provides arm64 support for Opus. Tested on
iOS, Android, and Ubuntu 14.04.
The patch sequence was written on top of Viswanath Puttagunta's Ne10
patches, but all but the second ("Reorganize pitch_arm.h") should, I
think, apply independently of it. It does depends on my previous
intrinsics configury reorganization, however.
Comments welcome.

[Aarch64 00/11] Patches to enable Aarch64 (arm64) optimizations, rebased to current master.
Here are my aarch64 patches rebased to the current tip of Opus master.
They're largely the same as my previous patch set, with the addition
of the final one (the Neon fixed-point implementation of
xcorr_kernel). This replaces Viswanath's Neon fixed-point
celt_pitch_xcorr, since xcorr_kernel is used in celt_fir and celt_iir
as well.
These have been tested for correctness under qemu
