      aarch64: vp9itxfm: Skip empty slices in the first pass of idct_idct 16x16 and 32x32 · 8b11a89c

      Previously all subpartitions except the eob=1 (DC) case ran with
      the same runtime:
      
      vp9_inv_dct_dct_16x16_sub16_add_neon:   1373.2
      vp9_inv_dct_dct_32x32_sub32_add_neon:   8089.0
      
      By skipping individual 8x16 or 8x32 pixel slices in the first pass,
      we reduce the runtime of these functions like this:
      
      vp9_inv_dct_dct_16x16_sub1_add_neon:     235.3

      vp9_inv_dct_dct_16x16_sub16_add_neon:   1372.1
      vp9_inv_dct_dct_32x32_sub1_add_neon:     555.1
      vp9_inv_dct_dct_32x32_sub2_add_neon:    5190.2
      vp9_inv_dct_dct_32x32_sub4_add_neon:    5180.0
      vp9_inv_dct_dct_32x32_sub8_add_neon:    5183.1
      vp9_inv_dct_dct_32x32_sub12_add_neon:   6161.5
      vp9_inv_dct_dct_32x32_sub16_add_neon:   6155.5
      vp9_inv_dct_dct_32x32_sub20_add_neon:   7136.3

      vp9_inv_dct_dct_32x32_sub32_add_neon:   8098.8
      
      I.e. in general a very minor overhead for the full subpartition case due
      to the additional cmps, but a significant speedup for the cases when we
      only need to process a small part of the actual input data.

      I.e. in general a very minor overhead for the full subpartition case due

      when we only need to process a small part of the actual input data.
      
      In common VP9 content in a few inspected clips, 70-90% of the non-dc-only
      16x16 and 32x32 IDCTs only have nonzero coefficients in the upper left
      8x8 or 16x16 subpartitions respectively.

      arm: vp9itxfm: Only reload the idct coeffs for the iadst_idct combination · ecd343aa
      Martin Storsjö authored
      This avoids reloading them if they haven't been clobbered, if the
      first pass also was idct.
      
      This is similar to what was done in the aarch64 version.

      arm: vp9itxfm: Rename a macro parameter to fit better · f69dd26d
      Martin Storsjö authored
      Since the same parameter is used for both input and output,
      the name inout is more fitting.
      
      This matches the naming used below in the dmbutterfly macro.
