      Remove unused vp8_get4x4sse_cs_mmx declaration · 2cbd9620
      John Koleszar authored
      This declaration did not match the prototype_sad() prototype, but was
      unused in this translation unit, so it is removed instead. Fixes
      issue 290.

      Increase static linkage, remove unused functions · 429dc676
      John Koleszar authored
      A large number of functions were defined with external linkage, even
      though they were only used from within one file. This patch changes
      their linkage to static and removes the vp8_ prefix from their names,
      which should make it more obvious to the reader that the function is
      contained within the current translation unit. Functions that were
      not referenced were removed.
      These symbols were identified by:
        $ nm -A libvpx.a | sort -k3 | uniq -c -f2 | grep ' [A-Z] ' \
          | sort | grep '^ *1 '

      In real-time mode, vp8_sad16x16 function is called heavily in
      motion search part. Improvement of this function gives 1.2%
      encoding performance gain (real-time mode, tulip clip).

      is set to 15. the max value for any frame is 32 (modifier = 16,

      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

      Convert [4][4] matrices to [16] arrays. · 8f75ea6b
      Timothy B. Terriberry authored
      Most of the code that actually uses these matrices indexes them as
       if they were a single contiguous array, and coverity produces
       reports about the resulting accesses that overflow the static
       bounds of the first row.
      This is perfectly legal in C, but converting them to actual [16]
       arrays should eliminate the report, and removes a good deal of
       extraneous indexing and address operators from the code.

      This rewriting reflects changes made in commit "Improve the
      accuracy of forward walsh-hadamard transform". Since this function
      is not called much, only a small encoder performance gain (~0.5% )
      is seen.

      Add SSE2 subtract functions · 4db20765
      Yunqing Wang authored
      Instead of doing 8-bit data unpack and 16-bit subtraction, use
      psubb to do 16 8-bit subtractions and pcmpgtb to preserve the
      sign information. This does not bring noticable gain since
      these functions are not called frequently.
