      Fix pedantic compiler warnings · 0164a1cc
      John Koleszar authored
      Allows building the library with the gcc -pedantic option, for improved
      portabilty. In particular, this commit removes usage of C99/C++ style
      single-line comments and dynamic struct initializers. This is a
      continuation of the work done in commit 97b766a4, which removed most
      of these warnings for decode only builds.

      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.

      update arm idct functions · 56f5a9a0
      Johann authored
      Jeff Muizelaar posted some changes to the idct/reconstruction c code.
      This is the equivalent update for the arm assembly.
      
      This shows a good boost on v6, and a minor boost on neon.
      Here are some numbers for highway in qcif, 2641 frames:
      HEAD neon: ~161 fps
      new neon:  ~162 fps
      HEAD v6:   ~102 fps
      new v6:    ~106 fps
      
      The following functions have been updated for armv6 and neon:
      vp8_dc_only_idct_add
      vp8_dequant_idct_add
      vp8_dequant_dc_idct_add
      
      Conflicts:
      
      	vp8/decoder/arm/armv6/dequantdcidct_v6.asm
      	vp8/decoder/arm/armv6/dequantidct_v6.asm
      
      Resolved by removing these files. When I rewrote the functions, I also
      moved the files to dequant_dc_idct_v6.asm/dequant_idct_v6.asm
