      Full search SAD function optimization in SSE4.1 · 71ecb5d7
      Yunqing Wang authored
      Use mpsadbw, and calculate 8 sad at once. Function list:
      vp8_sad16x16x8_sse4
      vp8_sad16x8x8_sse4
      vp8_sad8x16x8_sse4
      vp8_sad8x8x8_sse4
      vp8_sad4x4x8_sse4
      
      (test clip: tulip)
      For best quality mode, this gave encoder a 5% performance boost.
      For good quality mode with speed=1, this gave encoder a 3%
      performance boost.

      Fix half-pixel variance RTCD functions · a0ae3682
      John Koleszar authored
      This patch fixes the system dependent entries for the half-pixel
      variance functions in both the RTCD and non-RTCD cases:
      
        - The generic C versions of these functions are now correct.
          Before all three cases called the hv code.
      
        - Wire up the ARM functions in RTCD mode
      
        - Created stubs for x86 to call the optimized subpixel functions
          with the correct parameters, rather than falling back to C
          code.

      Add half-pixel variance RTCD functions · 209d82ad
      John Koleszar authored
      NEON has optimized 16x16 half-pixel variance functions, but they
      were not part of the RTCD framework. Add these functions to RTCD,
      so that other platforms can make use of this optimization in the
      future and special-case ARM code can be removed.
      
      A number of functions were taking two variance functions as
      parameters. These functions were changed to take a single
      parameter, a pointer to a struct containing all the variance
      functions for that block size. This provides additional flexibility
      for calling additional variance functions (the half-pixel special
      case, for example) and by initializing the table for all block sizes,
      we don't have to construct this function pointer table for each
      macroblock.

      cosmetics: trim trailing whitespace · 94c52e4d
      John Koleszar authored
      When the license headers were updated, they accidentally contained
      trailing whitespace, so unfortunately we have to touch all the files
      again.
