* x86/vp9lpf: simplify 2nd transpose in 44/48/88/84.Clément Bœsch2014-02-081-66/+48
| | | | | | | | | | | | | | | | For non-avx optims, this saves 8 movs. before: 1785 decicycles in ff_vp9_loop_filter_h_44_16_ssse3, 524129 runs, 159 skips 3327 decicycles in ff_vp9_loop_filter_h_48_16_ssse3, 262116 runs, 28 skips 2712 decicycles in ff_vp9_loop_filter_h_88_16_ssse3, 4193729 runs, 575 skips 3237 decicycles in ff_vp9_loop_filter_h_84_16_ssse3, 524061 runs, 227 skips after: 1768 decicycles in ff_vp9_loop_filter_h_44_16_ssse3, 524062 runs, 226 skips 3310 decicycles in ff_vp9_loop_filter_h_48_16_ssse3, 262107 runs, 37 skips 2719 decicycles in ff_vp9_loop_filter_h_88_16_ssse3, 4193954 runs, 350 skips 3184 decicycles in ff_vp9_loop_filter_h_84_16_ssse3, 524236 runs, 52 skips

* x86/vp9lpf: add ff_vp9_loop_filter_h_{48,84}_16_{sse2,ssse3,avx}().Clément Bœsch2014-01-301-28/+31
| | | | | 5.40s → 5.30s overall decode time with -threads 1 on ped1080p.webm (i7 920, ssse3)

| | | | | | | | | | | | | 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.
* x86/vp9lpf: add a preload system in FILTER_UPDATE.Clément Bœsch2014-01-271-27/+20
| | | | Allow some macro refactoring in filter14().
* x86/vp9lpf: refactor v/h using common macros for P7 to Q7.Clément Bœsch2014-01-271-136/+80

* x86/vp9lpf: faster P7..Q7 accesses.Clément Bœsch2014-01-271-113/+114
| | | | | | | | | Introduce 2 additional registers for stride3 and mstride3 to allow direct accesses (lea drops). 3931 → 3827 decicycles in ff_vp9_loop_filter_v_16_16_ssse3 Also uses defines to clarify the code.
* vp9/x86: add ff_vp9_loop_filter_[vh]_16_16_sse2().James Almer2014-01-171-6/+8
