Michael Niedermayer	bc488ec28a	avcodec/me_cmp: Fix crashes on ARM due to misalignment Adds a diff_pixels_unaligned() Fixes: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=872503 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	8 years ago
Ivan Kalvachev	43dab86bcd	opus_pvq_search: Restore the proper use of conditional define and simplify the function name suffix handling. Using named define properly documents the code paths. It also avoids passing additional numbered arguments through multiple levels of macro templates. The suffix handling is done by concatenation, like in other asm functions and avoid having two separate "cglobal" defines. Signed-off-by: Ivan Kalvachev <ikalvachev@gmail.com>	8 years ago
Rostislav Pehlivanov	3c99523a28	opus_pvq_search: split functions into exactness and only use the exact if its faster This splits the asm function into exact and non-exact version. The exact version is as fast or faster on newer CPUs (which EXTERNAL_AVX_FAST describes well) whilst the non-exact version is faster than the exact on older CPUs. Also fixes yasm compilation which doesn't accept !cpuflags(avx) syntax. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago

Rostislav Pehlivanov	8e53cd1fab	ops_pvq_search: remove dead macro There's no point in toggling it, even for debugging. Its just worse. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago

Wan-Teh Chang	ea1ca17be2	avcodec/x86/cavsdsp: Delete #include "libavcodec/x86/idctdsp.h". This file already has #include "idctdsp.h", which is resolved to the idctdsp.h header in the directory where this file resides by compilers. Two other files in this directory, libavcodec/x86/idctdsp_init.c and libavcodec/x86/xvididct_init.c, also rely on #include "idctdsp.h" working this way.

James Almer	9d5e81d3b1	Revert "x86/sbrdsp: remove unnecessary sign extend instruction in apply_noise_main" This reverts commit `24bb7db403`. noise has to after all be sign extended, not zero extended, on tests other than checkasm. Fixes most aac tests broken by the now reverted commit.	8 years ago
