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. Linfeng Zhang

Patch cleaning up Opus x86 intrinsics configury

The attached patch cleans up Opus's x86 intrinsics configury. It: * Makes ?enable-intrinsics work with clang and other non-GCC compilers * Enables RTCD for the floating-point-mode SSE code in Celt. * Disables use of RTCD in cases where the compiler targets an instruction set by default. * Enables the SSE4.1 Silk optimizations that apply to the common parts of Silk when Opus is built in

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi Jesus, Thanks for the report. As far as I can tell, what's happening is that when intrinsics are enabled, we compile all tests with -msse4.1, even when it's only run-time detected. In most cases, that doesn't cause any issue, but sometimes the compiler will take the C code and generate an SSEx instruction on its own. I think this is

Opus 1.1.1 beta breaks floating point integrity?

HI trying to build libopus beta compiler complains about more fixed point specific names referenced in common unconditional code Particularly: ./celt/x86/celt_lpc_sse.c(100): error: identifier "SIG_SHIFT" is undefined noA = EXTEND32(1) << SIG_SHIFT >> 1; ^ SIG_SHIFT is defined in arch.h provided FIXED_POINT is used (not on floating point build) and silk/x86/x86_silk_map.c unconditionally references alot na...

[PATCH v1] cover: armv7: celt_pitch_xcorr: Introduce ARM neon intrinsics

Hi, Optimizes celt_pitch_xcorr for ARM NEON floating point. Changes from RFCv3: - celt_neon_intr.c - removed warnings due to not having constant pointers - Put simpler loop to take care of corner cases. Unrolling using intrinsics was not really mapping well to what was done in celt_pitch_xcorr_arm.s - Makefile.am Removed explicit -O3 optimization - test_unit_mathops.c,
