      This commit continues the process of converting to the new RTCD
      system.

      New RTCD implementation · a910049a
      John Koleszar authored
      This is a proof of concept RTCD implementation to replace the current
      system of nested includes, prototypes, INVOKE macros, etc. Currently
      only the decoder specific functions are implemented in the new system.
      Additional functions will be added in subsequent commits.
      
      Overview:
        RTCD "functions" are implemented as either a global function pointer
        or a macro (when only one eligible specialization available).
        Functions which have RTCD specializations are listed using a simple
        DSL identifying the function's base name, its prototype, and the
        architecture extensions that specializations are available for.
      
      Advantages over the old system:
        - No INVOKE macros. A call to an RTCD function looks like an ordinary
          function call.
        - No need to pass vtables around.
        - If there is only one eligible function to call, the function is
          called directly, rather than indirecting through a function pointer.
        - Supports the notion of "required" extensions, so in combination with
          the above, on x86_64 if the best function available is sse2 or lower
          it will be called directly, since all x86_64 platforms implement
          sse2.
        - Elides all references to functions which will never be called, which
          could reduce binary size. For example if sse2 is required and there
          are both mmx and sse2 implementations of a certain function, the
          code will have no link time references to the mmx code.
        - Significantly easier to add a new function, just one file to edit.
      
      Disadvantages:
        - Requires global writable data (though this is not a new requirement)
        - 1 new generated source file.

      Moved dequant idct into common · a53d5a4c
      Scott LaVarnway authored
      These functions are now used by the encoder.
      This is WIP with the goal of creating a common idct/add for
      the encoder and decoder.  A boost of 1.8% was seen for
      the HD rt test clip used.
      
      [Tero] Added needed changes to ARM side.

      Modified the inverse walsh to output directly · 4a91541c
      Scott LaVarnway authored
      to the dqcoeff or qcoeff buffer.  The encoder would
      populate the dc coeffs of the y blocks as a separate
      stage (recon_dcblock) and the decoder would use a special
      version of the idct.  This change eliminates the extra copy
      and reduces the code footprint.
      
      [Tero] Added needed changes to armv6 and NEON assembly.

      Remove usage of predict buffer for decode · ed9c66f5
      Scott LaVarnway authored
      Instead of using the predict buffer, the decoder now writes
      the predictor into the recon buffer.  For blocks with eob=0,
      unnecessary idcts can be eliminated.  This gave a performance
      boost of ~1.8% for the HD clips used.
      
      Tero: Added needed changes to ARM side and scheduled some
            assembly code to prevent interlocks.
      
      Patch Set 6:  Merged (I1bcdca7a95aacc3a181b9faa6b10e3a71ee24df3)
      into this commit because of similarities in the idct
      functions.
      Patch Set 7: EC bug fix.

      With this fix, the experimental branch now builds and encodes correctly
      with the following two configure options respectively:
      --enable-experimental --enable-t8x8
      --enable-experimental

      fix implicit declarations · b90a072f
      Johann authored
      ARM used to explicitly remove this file from the build. With the RTCD
      changes, that's no longer possible. These errors also exist for x86 w/o
      RTCD, but that's not the default configuration

      Rework idct calling structure. · 93c32a55
      Fritz Koenig authored
      Moving the eob structure allows for a non-struct based
      function to handle decoding an entire mb of
      idct/dequant/recon data.  This allows for SIMD functions
      to idct/dequant/recon multiple blocks at once.
      
      SSE2 implementation gives 3% gain on Atom.
