      Lowbd intrapred DC/TOP/LEFT/128/V/H avx2 · 23c61903
      Yi Luo authored
      For prediction block width equal to 32, avx2 can further speedup
      the prediction function (i7-6700):
      32x32     avx2 v. sse2
      DC        ~1.4x
      top       ~1.5x

      v         ~1.6x
      h         ~1.2x

      DC        ~2.2x

      left      ~1.6x
      128       ~1.8x
      v         ~1.9x
      Note: 32x16 H_PRED on avx2 does not run faster enough than sse2 yet.

      Build static libaom without internal deps in CMake. · 78516fca
      Tom Finegan authored
      Change the internal lib targets so that external apps
      need link only libaom instead of all internal library
      targets and libaom.

      Add shared library support to the CMake build. · 84f2d796
      Tom Finegan authored
      This is enabled via:
      $ cmake path/to/aom -DBUILD_SHARED_LIBS=1
      Currently supports only Linux and MacOS targets. Symbol visibility
      is handled by exports.cmake and its helpers exports_sources.cmake
      and generate_exports.cmake.
      Some sweeping changes were required to properly support shared libs
      and control symbol visibility:
      - Object libraries are always linked privately into static
      - Static libraries are always linked privately into eachother
        in the many cases where the CMake build merges multiple library
      - aom_dsp.cmake now links all its targets into the aom_dsp static
        library target, and privately links aom_dsp into the aom target.
      - av1.cmake now links all its targets into the aom_av1 static library
        target, and privately links in aom_dsp and aom_scale as well. It
        then privately links aom_av1 into the aom target.
      - The aom_mem, aom_ports, aom_scale, and aom_util targets are now
        static libs that are privately linked into the aom target.
      - In CMakeLists.txt libyuv and libwebm are now privately linked into
        app targets.
      - The ASM and intrinsic library functions in aom_optimization.cmake
        now both require a dependent target argument. This facilitates the
        changes noted above regarding new privately linked static library
        targets for ASM and intrinsics sources.

      ext-inter: Delete dead code · 0f3c94e1
      David Barker authored
      Patches https://aomedia-review.googlesource.com/c/11987/
      and https://aomedia-review.googlesource.com/c/11988/
      replaced the old masked motion search pipeline with
      a new one which uses different SAD/SSE functions.
      This resulted in a lot of dead code.
      This patch removes the now-dead code. Note that this
      includes vectorized SAD/SSE functions, which will need
      to be rewritten at some point for the new pipeline. It
      also includes the masked_compound_variance_* functions
      since these turned out not to be used by the new pipeline.
      To help with the later addition of vectorized functions, the
      masked_sad/variance_test.cc files are kept but are modified
      to work with the new functions. The tests are then disabled
      until we actually have the vectorized functions.
