[PATCH] fix alignment exceptions

We see the MOVQ instruction but this patch deliberately uses it rather than MOVQDA (load 128-bits aligned). We were seeing that with the trace below, the final invocation is not 128-bit aligned but MOVQDA insists on it (the calling function was pitch_sse4_1.c:90, in the 4-way N - i >= 4 loop). 07-31 11:00:13.469 210 2540 <(469)%20210-2540> D opus_sse1: RBE celt_inner_prod_sse4_1: x 0xeff3deb0 y 0xeff3deb0 N 32 07-31 11:00:13.469 210 2540 <(469)%20210-2540> D opus_sse1: RBE celt_inner_prod_sse4_1: x 0xeff3d7b0 y 0xeff3d7b0 N 32 07...

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

[PATCH] fix alignment exceptions

Hi, Please find attached a patch to fix alignment exceptions. Without this change, we were seeing occasional alignment faults when using this with clang.

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
