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,

ASM runtime detection and optimizations
I wrote a proof of concept regarding the cpu capabilities runtime
detection and choice of optimized function. I follow design which had
been discussed on IRC.
Also, i notice a little drawback: we must propagate the arch index
through functions which don't have codec state as argument.
However, if it's look good, i will continue to implement it.
Best regards,
