The optimization is bit-exact with C function.

This optimization speeds up SILK encoder (floating point) as following:

AMD Zen:
Complexity 0-5 :      0%
Complexity 6-7 : 3 -  7%
Complexity 8-10: 8 - 15%

Intel Skylake:
Complexity 0-5 :       0%
Complexity 6-7 : 14 - 18%
Complexity 8-10: 17 - 22%

Adapted by Jean-Marc Valin

Starting with compute_linear()

No dependency on the data files if no DNN code enabled

Not used by anything yet

can't link woth libopus since it's already #including C files

Add unit tests for opus_packet_extensions_count, opus_packet_extensions_parse,
and opus_packet_extensions_generate. Add various assertions for NULL buffers or
negative length arguments. Add explicit check for invalid length in
opus_packet_extensions_count. Check for extension id >127 in
opus_packet_extensions_generate. Check for invalid length input in
opus_packet_extensions_generate.

Add doc/trivial_example.c to the autotools build so we get
some minimal verification that the code compiles.

We now include the object files for those rather than attempt to

The optimization is bit exact with C function.

This optimization speeds up fixed-point SILK encoder on NEON about
5% to 8%. (Tested on Acer Chromebook, ARMv7 Processor rev 3 (v7l).)

It checks that no clearly unstable filter passes the LPC_inv_pred_gain()
test. Also, this will make it possible to check assembly for correctness.

Modified from an original patch from Linfeng Zhang <linfengz@google.com>.

Remove version.mk and references to it in the repo.

genversion.bat will now generate the same version strings as
update_version script, i.e. without 'v' prefix and without a
fallback if git archive is used.

If run from a release tarball it'll use package_version,
like configure. If run from a git repo, it will use the same
'git describe' with '-dirty' as update_version.
