      Disconnect ARM tgt_isa from dsp extensions · 89210284
      Fritz Koenig authored
      A processor with ARMv7 instructions does not
      necessarily have NEON dsp extensions.  This CL
      has the added side effect of allowing the ability
      to enable/disable the dsp extensions cleanly.

      clean up bilinear filter · e5aaac24
      Johann authored
      make reference version of bilinear_filters short.
      use reference versions of bilinear_filters and sub_pel_filters when
      possible.
      
      recognize that Width was being passed into
      filter_block2d_bil_first_pass multiple times. ARM version had already
      fixed this. propegate to C.
      
      change references to src_pixels_per_line to src_pitch and standardize on
      src/dst (instead of input/output).
      
      recognize that first_pass is only run in the verticle and second_pass
      only horizontal. ARM version had already fixed this. propegate to C

      Eliminate more warnings. · 97b766a4
      Timothy B. Terriberry authored
      This eliminates a large set of warnings exposed by the Mozilla build
       system (Use of C++ comments in ISO C90 source, commas at the end of
       enum lists, a couple incomplete initializers, and signed/unsigned
       comparisons).
      It also eliminates many (but not all) of the warnings expose by newer
       GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite
       without checking the return values).
      There are a few spurious warnings left on my system:
      
      ../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used
       uninitialized in this function
      gcc seems to be unable to figure out that the value shortcut doesn't
       change between the two if blocks that test it here.
      
      ../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned
       expression >= 0 is always true
      ../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned
       expression >= 0 is always true
      This is true, so far as it goes, but it's comparing against an enum,
       and the C standard does not mandate that enums be unsigned, so the
       checks can't be removed.

      Add 4-tap version of 2nd-pass ARMv6 MC filter. · 18dc92fd
      Timothy B. Terriberry authored
      The existing code applied a 6-tap filter with 0's on either end.
      We're already paying the branch penalty to avoid computing the two
       extra columns needed as input to this filter.
      We might as well save time computing the filter as well.
      This reduces the inner loop from 21 instructions to 16, the number
       of loads per iteration from 4 to 1, and the number of multiplies
       from 7 to 4.
      The gain in overall decoding performance, however, is small (less
       than 1%).
      
      This change also means we now valgrind clean on ARMv6, which is
       its real purpose.
      The errors reported here were valgrind's fault (it does not detect
       that 0 times an uninitialized value is initialized), but Julian
       Seward says it would slow down valgrind considerably to make such
       checks.
      Speeding up libvpx rather, even by a small amount, seems a much
       better idea if only to enable proper valgrind checking of the
       rest of the codec.

      cosmetics: trim trailing whitespace · 94c52e4d
      John Koleszar authored
      When the license headers were updated, they accidentally contained
      trailing whitespace, so unfortunately we have to touch all the files
      again.
