Some of the fields present in NE10's float state struct are not
 present in the fixed-point version, but we were generating
 initializers for them anyway.
Also, the float modes were not up-to-date with the output of
 dump_modes.

Optimize opus decode (float only) use case using ARM NE10.
Mainly effects opus_ifft and ctl_mdct_backward and related
functions.

Work based on previous Encode optimization using ARM NE10
library. See previous commit for details on how to enable
this.

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.

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.

In optimized mode, don't force Clang to use explicit load/store for _mm_cvtepi16_epi32, only for _mm_cvtepi8_epi32. Adjust comment accordingly.

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.

We already needed these macros for gcc with optimizations disabled,
 but it appears clang needs them all the time.

Thanks to Jonathan Lennox for the report.

This way we won't break this by accident.

During review of c95c9a04, I replaced a call to
 _mm_cvtepi8_epi32() with the OP_CVTEPI16_EPI32_M64() macro (note
 the 16 instead of 8).
Make a separate OP_CVTEPI8_EPI32_M32() macro and use that instead.

Thaks to Wei Zhou for the report.

This should suppress our current issues with unused parameters,
 unused variables, and set-but-not-used variables.

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.

This should not take an arch parameter, so it can properly be used
 as a fallback for accelerated versions which do not.
This patch instead provides a separate version which can call
 accelerated helpers for platforms that have taken that approach.

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.
