      the difference between src and dst will be signed, the error will be
      unsigned.

      Upgrade fwht4x4_mmx() to fwht4x4_sse2() for vp9 and vp10. · af7fb17c
      Linfeng Zhang authored
      Function level timing test shows about 27% time saving on
      a Xeon E5-2680 v2 desktop.
      
      Rename vp9_dct_sse2.c to vp9_dct_intrin_sse2.c for vp9 and
      rename dct_sse2.c to dct_intrin_sse2.c for vp10 to avoid
      duplicate basenames.
      
      Actually vp9_fwht4x4_mmx/sse2() and vp10_fwht4x4_mmx/sse2()
      are identical. TODO: They should be unified later if there is
      no intention to keep a duplicate.

      Unify the high bit-depth forward hybrid transforms · e253eaa0
      Jingning Han authored
      The SSE2 version high bit-depth forward hybrid transforms are
      essentially using the C functions via cross referencing to 1-D
      functions in vp9_dct.c. This commit unifies the two versions and
      removes the unnecessary dependency.

      With the sad functions, and hopefully the variance functions soon,
      moving to the vpx_dsp location, place the defines used in the
      reference C code in a common location.

      replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNED · fd3658b0
      James Zern authored
      this macro was used inconsistently and only differs in behavior from
      DECLARE_ALIGNED when an alignment attribute is unavailable. this macro
      is used with calls to assembly, while generic c-code doesn't rely on it,
      so in a c-only build without an alignment attribute the code will
      function as expected.

      Incorporate WRAPLOW macro into non-highbitdepth tx · d50716fa
      Deb Mukherjee authored
      Incorporates the WRAPLOW macro into the non-highbitdepth transforms
      to aid hardware verification between a software C model and an
      intended hardware implementation though the use of the configure
      options: --enable-experimental --enable-emulate-hardware.
      Note that to avoid further discrepancies between the sse/sse2
      implementations of the transforms and the C implementation, when the
      emulate hardware option is invoked, we also disable sse/sse2/etc.
      
      Also incudes some minor cleanups/renaming etc.

      Adds high bitdepth transform functions and tests · 10783d4f
      Deb Mukherjee authored
      Adds various high bitdepth transform functions and tests.
      Much of the changes are related to using typedefs tran_low_t
      and tran_high_t for the final transform cofficients and intermediate
      stages of the transform computation respectively rather than fixed
      types int16_t/int. When vp9_highbitdepth configure flag is off,
      these map tp int16_t/int32_t, but when the flag is on, they map
      to int32_t/int64_t to make space for needed extra precision.

      Rework unit test for 8x8 transformation · 5c2696c3
      Jingning Han authored
      This commit reworks the unit test for 8x8 forward/inverse
      transformation. It adds extreme input value test to detect overflow
      issues in the intermediate steps.
      
      It temporarily disables unit test for the SSSE3 version, which
      showed overflow failure in the new test conditions.
