      acm_random: provide full range for Rand16() · 615230b8
      James Zern authored
      the gtest implementation used only returns values between 0 and 2^31-1
      + temporarily disable some tests in fdct8x8_test which misbehave with the
        new range

      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.

      Added ClearSystemState in a unit test · e494df1a
      Yaowu Xu authored
      There is another unit test that has been failing randomly on win32
      build. Investigation has shown that the failure was caused by simd
      register state is not reset appropriately in the fdct8x8 test. This
      commit added ClearSystemState() in the teardown of this test, tests
      showed it resolved the random failure issue for win32 build.

      Yaowu Xu authored
      The mix use of double type and simd code caused invalid values stored
      in double variables, further caused unit tests to fail. The failures
      were only observed on x86-win32-vs9 build with vs2008.

      Scott LaVarnway authored
      This patch eliminates the intermediate diff buffer usage by
      combining the short idct and the add residual into one function.
      The encoder can use the same code as well.
