      Avoid UB from misaligned loads/stores in loopfilter code · 129afee7
      Rupert Swarbrick authored
      This patch changes 32 bit loads and stores (which did trigger
      undefined behaviour when the pointer wasn't aligned) to use the
      xx_storel_32 synonym. This should also just generate a MOVD and is
      less verbose to boot!
      The patch also changes store_buffer_horz_8 to take its SSE register by
      value rather than by pointer. The most restrictive ABI for passing SSE
      registers by value is win32, where you can pass at most 3. There's
      only one here, so it should be fine.

      Avoid UB from misaligned loads in variance_sse2.c · d2dea66b
      Rupert Swarbrick authored
      The undefined behaviour came from READ64, whose loads compile to a
      MOVD but which is technically incorrect if p is misaligned. This patch
      rewrites it, and the other loads and stores in the file, to use the
      xx_* functions from synonyms.h

      Avoid UB from misaligned loads in selfguided_sse4.c · 84ffea31
      Rupert Swarbrick authored
      This follows on from the previous patch, which corrects xx_loadl_32
      for misaligned addresses. Calls to xx_loadl_32 in selfguided_sse4.c
      are all followed by a zero-extend, so this patch packages the two into
      the inlinable functions xx_load_extend_8_16 and xx_load_extend_8_32.
      There were also some hand-rolled loads (which matched the old body of
      xx_loadl_32 and weren't strictly correct when the pointer was
      misaligned). This patch fixes them up to use xx_load_extend_8_32.

      Avoid UB in xx_loadl/storel_32 helper functions · be0aa4ad
      Rupert Swarbrick authored
      The previous code dereferenced a uint32_t * that might be misaligned,
      which is technically undefined behaviour in C. This version uses the
      right (cryptically named) Intel intrinsics to generate a MOVD without
      making any claims about the alignment of the pointer.

      Define av1_foreach_rest_unit_in_frame · 33ed9e69
      Rupert Swarbrick authored
      This is the last stage in a quest to move all knowledge of the layout
      of restoration units across the frame into restoration.c. Now this is
      done, we can change how they are laid out (to split them properly at
      tile boundaries) without having to change code in any other file.

      Simplify the search in pickrst.c · 1a96c3f5
      Rupert Swarbrick authored
      The end results should be essentially the same, except hopefully a
      little better because the previous code got the costing slightly
      wrong if there were multiple tiles.
      The code was doing something quite complicated to search for the best
      restoration types; this patch makes it much simpler. Basically,
      av1_pick_filter_restoration loops over the planes in the image. For
      each plane, it loops over the possible restoration types, calling
      search_rest_type for each one.
      search_rest_type iterates over the restoration units in the image,
      resetting the current context on tile boundaries and calling
      search_<rest_type> for each restoration unit.
      The search_norestore function just computes the SSE error with no
      restoration. The search_wiener and search_sgrproj functions compute
      the best set of coefficients and then the resulting SSE error with
      those coefficients (ignoring the bit cost, so the result can be
      re-used for switchable restoration).
      In all cases but search_norestore, the search function has to decide
      what restoration type is best for each restoration unit. For example,
      search_wiener could choose to enable or disable Wiener filtering on
      this unit.
      Eventually, search_rest_type calculates the RDCOST after summing bit
      rates and SSE errors over the restoration units. This cost gets
      returned to av1_pick_filter_restoration which can then choose the best
      frame-level restoration type.

      JNT_COMP: 1. Init version of experiment JNT_COMP · d867c9aa
      Cheng Chen authored
      Enable to assign distance based weight for joint compound prediction.
      (w0, w1) are weights for two predictors of different distance to
      current frame.
      Use 4 bit precision for quantized distance weight. e.g.
      the prediction is generated as
      value = (w0 * p0 + w1 * p1) >> n
      w0 + w1 = (1 << n), n = 4;
