      Simplify Daala inverse TX toplevel for constant shift · 359854fe
      Monty Montgomery authored
      Rather than backing out all the LGT-related shifting matrices
      throughout the existing TX code, separate out and simplify Daala
      inverse TX into a single dedicated entry point.  When DAALA_TX is
      enabled, CONFIG_HIGHBITDEPTH is also forced, and all of Daala TX
      (lowbd and highbd) uses this single TX dispatch.
      
      This patch is purely non-functional changes.

      Disable only coding transform SIMD for DAALA_TX · 1d190950
      Monty Montgomery authored
      Rather than disabling MMX (well, all of SIMD) for daala transforms,
      selectively disable the AV1 TX SIMD through
      av1/common/av1_rtcd_defs.pl
      
      This also requires quite a few testing build fixups.

      Unify FWD_TXFM_PARAM and INV_TXFM_PARAM · 27319b6e
      Lester Lu authored
      Change two similar structs, FWD_TXFM_PARAM and INV_TXFM_PARAM,
      into a common struct: TxfmParam. Its definition is moved to
      aom_dsp/txfm_common.h to simplify dependency.
      
      This change is made so that, in later changes of the LGT
      experiment, functions requiring FWD_TXFM_PARAM and
      INV_TXFM_PARAM, such as get_fwd_lgt4 and get_inv_lgt4, can
      also be unified.

      Signature changes for the LGT experiment · d8b1ddce
      Lester Lu authored
      The input arguments of av1_fht* and av1_iht* functions (and their
      HBD versions) are slightly changed. Input arguments tx_type and
      bd are carried by a struct fwd_txfm_param/inv_txfm_param. This
      struct is meant to later on carry other prediction information,
      such as intra top/left boundaries to the transform level, so
      that the choice of transforms can be more adaptive to the
      prediction mode and local video content.

      Remove deprecated high-bitdepth functions · 31c66502
      Sarah Parker authored
      This unifies the codepath for high-bitdepth transforms and deletes
      all calls to the old deprecated versions. This required reworking
      the way 1d configurations are combined in order to support rectangular
      transforms.
      
      There is one remaining codepath that calls the deprecated 4x4 hbd
      transform from encoder/encodemb.c. I need to take a closer look
      at what is happening there and will leave that for a followup
      since this change has already gotten so large.

      Drop support for CONFIG_EMULATE_HARDWARE · c6a48a25
      Sebastien Alaiwan authored
      This experiment complexifies DSP function dispatch, without bringing
      any real value (it's non-normative arbitrary behaviour).
      Moreover, it only has an effect on obsolete transforms, the new ones
      don't implement this mechanism.

      This commit bring all up-to-date changes from master that are

      we had to cherry pick the following commits to get those changes:

      Allows building simple targets with sane default flags.

      Removed -funroll-loops
      
      psnr.c: use int64_t for sum of differences
      
      Since the values can be negative.
      
      *.asm: normalize label format
      
      add a trailing ':', though it's optional with the tools we support, it's
      more common to use it to mark a label. this also quiets the
      orphan-labels warning with nasm/yasm.
      
      BUG=b/29583530
      
      Prevent negative variance
      
      Due to rounding, hbd variance may become negative. This commit put in
      check and clamp of negative values to 0.

      inadvertently lost in the final patchset of:
      078dff7 configure: remove old visual studio support (<2010)
      
      this prevents an empty CONFIG_VS_VERSION and avoids make failure
      
      Require x86inc.asm
      
      Force enable x86inc.asm when building for x86. Previously there were
      compatibility issues so a flag was added to simplify disabling this
      code.
      
      The known issues have been resolved and x86inc.asm is the preferred
      abstraction layer (over x86_abi_support.asm).

      Update vpx subpixel 1d filter ssse3 asm
      
      Speed test shows the new vertical filters have degradation on Celeron
      Chromebook. Added "X86_SUBPIX_VFILTER_PREFER_SLOW_CELERON" to control
      the vertical filters activated code. Now just simply active the code
      without degradation on Celeron. Later there should be 2 set of vertical
      filters ssse3 functions, and let jump table to choose based on CPU type.
      
      improve vpx_filter_block1d* based on replace paddsw+psrlw to pmulhrsw
      
      Make set_reference control API work in VP9
      
      Moved the API patch from NextGenv2. An example was included.
      To try it, for example, run the following command:

      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.
