Commit 6577534a switched from using __get_cpuid() to
 __get_cpuid_count(), but the corresponding configure check was not
 updated.
Since __get_cpuid_count() was introduced much later, make sure we
 check for the function we actually use.

Thanks to Mark Harris for the report.

Adding the OPUS_GET_IN_DTX() query

We're adding the ambisonics API

Enables "safes" assertions even with ENABLE_ASSERTIONS isn't set

It adds a libssp-0.dll dependency and prevents static linking

The size overhead seems to be about 1% and the speed overhead is
"in the noise" (<2%).
The automake code is copied from opus-tools

Put the colon ':' before the continuation dots like all the
other entries.

As reported by agatx in https://trac.xiph.org/ticket/2291

Different distributions of doxygen have different default
values of HAVE_DOT setting, so we need to pick a specific
setting to avoid 'missing dot' warnings on some platforms.

Doxygen uses it to generate inclusion graphs for our various
header files, which is somewhat useful, but not essential.
We therefore enable dot if it's present (usually through
the parent graphviz package) but disable it if it's not
available, silencing the warning, but not giving uniform
results.

There are no tabs in source code.

This makes it match the formatting of the output for ARM assembly
better, and removes some redundant repetition of the word
"intrinsics".  It also fixes the output if a compiler supports RTCD
for Neon intrinsics but not assembly.

Uses NEON optimized fixed point FFT routines in NE10 library.

Viswanath Puttagunta authored 9 years ago and Jean-Marc Valin committed 9 years ago

Optimize opus encode (float only) usecase using ARM NE10
library. Mainly effects opus_fft and ctl_mdct_forward
and related functions.

This optimization can be used for ARM CPUs that have NEON
VFP unit. This patch only enables optimizations for ARMv7.

Official ARM NE10 library page available at
http://projectne10.github.io/Ne10/



To enable this optimization, use
--enable-intrinsics --with-NE10=<install_prefix>
or
--enable-intrinsics --with-NE10-libraries=<NE10_lib_dir> --with-NE10-includes=<NE10_includes_dir>

Compile time checks made during configure process to make sure
optimization option available only when compiler supports NEON
instrinsics.

Runtime checks made to make sure optimized functions only called
on appropriate hardware.
