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.

Run before any other project.

Avoids trying to create and replace version.h more than once which
led to file-locking errors with multicore builds.

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.

This library is linked statically with libopus.so, so nothing
 changes on an installed system.
This merely simplifies linking in the unit tests.
Based in part on a patch originally by Viswanath Puttagunta
 <viswanath.puttagunta@linaro.org>.

Enable x86 intrinsics when building in floating-point mode.
Support SSE as an arch value.
Use RTCD to conditionally enable existing floating-point Celt SSE code.
Call functions directly (without RTCD) when their architecture can be presumed.
Use SSE4.1 intrinsics optimized code for Silk even in floating-point mode.

Jonathan Lennox authored 9 years ago and Jean-Marc Valin committed 9 years ago

Move SSE2 and SSE4.1 intrinsics functions to separate files, to be compiled with appropriate compiler flags. Otherwise, compilers are allowed to take advantage of (e.g.) -msse4.1 to generate code that uses SSE4.1 instructions, even when no SSE4.1 intrinsics are explicitly used in the source.

Jonathan Lennox authored 9 years ago and Jean-Marc Valin committed 9 years ago

Actually try to compile intrinsics rather than using the output of --help.
Allow caller of configure script to set custom compiler options to enable intrinsics.
Detect when intrinsics are always available, without needing special compiler options.
Make naming of #defines for detected intrinsics support more systematic.

Optimize celt_pitch_xcorr function (for floating point)
using ARM NEON intrinsics for SoCs that have NEON VFP unit.

To enable this optimization, use --enable-intrinsics
configure option.

Compile time and runtime checks are also supported to make sure
this optimization is only enabled when the compiler supports
NEON intrinsics.

1. Only for fixed point on x86 platform (32bit and 64bit, uses SIMD
   intrinsics up to SSE4.2)
2. Use "configure --enable-fixed-point --enable-intrinsics" to enable
   optimization, default is disabled.
3. Official test cases are verified and passed.

The patch in 76e831d9 got us most of the way there, but
 out-of-tree builds required a second Makefile.am rule, which was
 missing @ARM2GNU_PARAMS@.
Also, the arm2gnu.pl was terminating argument processing on any
 argument beginning with --, rather than an argument that was just
 -- by itself (as is the normal convention in GNU programs).
That meant it never saw the --apple flag even when it was passed.

Thanks to Jonathan Lennox for the report and for testing.

Don't include the generated celt/arm/celt_pitch_xcorr_arm-gnu.S in the
dist tarball, but do include its celt_pitch_xcorr_arm.s source file.

Automake's dependency tracking seems to be confused by our asm
generation double-indirection. It's sufficient to have just
CLEANFILES = $(CELT_AM_SOURCES_ARM_ASM:.s.in=-gnu.S)
to fix the error about 'armopts-gnu.S' not being cleaned, but
celt_pitch_xcorr_arm-gnu.S is also not cleaned without raising
a warning. Therefore we explicitly clean both sets of ARM_ASM.
