* | | x86/vp9lpf: add ff_vp9_loop_filter_[vh]_88_16_{ssse3,avx}.Clément Bœsch2014-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 9680 decicycles in loop_filter_v_88_16_c, 4193765 runs, 539 skips 9233 decicycles in loop_filter_h_88_16_c, 4193751 runs, 553 skips 1929 decicycles in ff_vp9_loop_filter_v_88_16_ssse3, 4194118 runs, 186 skips 2738 decicycles in ff_vp9_loop_filter_h_88_16_ssse3, 4193861 runs, 443 skips 5.978 → 5.417 overall decode time on ped1080p.webm (-threads 1) Adding SSE2 support should be relatively trivial (just a matter of changing the pshufb [mask_mix] with something else), patch welcome.

| * | vp9/x86: use explicit register for relative stack references.Ronald S. Bultje2014-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, we explicitly modify rsp, which isn't necessarily universally acceptable, since the space under the stack pointer might be modified in things like signal handlers. Therefore, use an explicit register to hold the stack pointer relative to the bottom of the stack (i.e. rsp). This will also clear out valgrind errors about the use of uninitialized data that started occurring after the idct16x16/ssse3 optimizations were first merged.
