      Replace "inline" with OPUS_INLINE. · 7830cf1b
      Gregory Maxwell authored
      Newer versions of MSVC are unhappy with the strategy of the build
       environment redefining "inline" (even though they don't support the
       actual keyword). Instead we define OPUS_INLINE to the right thing
       in opus_defines.h.
      
      This is the same approach we use for restrict.

      Eliminate the ec_int32 and ec_uint32 typedefs. · 9bac8c17
      Timothy B. Terriberry authored
      These were used because the entropy coder originally came from
       outside libcelt, and thus did not have a common type system.
      It's now undergone enough modification that it's not ever likely to
       be used as-is in another codec without some porting effort, so
       there's no real reason to maintain the typedefs separately.
      Hopefully we'll replace these all again somedate with a common set
       of Opus typedefs, but for now this will do.
      
      This fixes an issue caused by commit 6c8acbf1, which moved the
       ec_ilog() prototype from entcode.h to ecintrin.h, where the
       ec_uint32 typedef was not yet available.
      Thanks to John Ridges for the report.

      EC_ILOG cleanups. · 6c8acbf1
      Timothy B. Terriberry authored
      Mark _BitScanReverse as an intrinsic, as this is not done by default
       in _DEBUG mode (thanks to Bjoern D. Rasmussen for the suggestion).
      Move the declaration of ec_ilog() to where the macro using it is
       defined, to ensure it is available when the macro is used.
      Thanks to John Ridges for the report.

      16-bit int fixes. · 285bc372
      Timothy B. Terriberry authored
      This fixes a number of issues for platforms with a 16-bit int, but
       by no means all of them.
      The type change for ec_window (for platforms where sizeof(size_t)==2)
       will break ABI (but not API) compatibility with libsilk and libopus,
       and reduce speed on x86-64, but allows the code to work in real-mode
       DOS without using the huge memory model, which is useful for testing
       16-bit int compliance.

      Refactor the entropy coder. · a093f4df
      Timothy B. Terriberry authored
      This unifies the byte buffer, encoder, and decoder into a single
       struct.
      The common encoder and decoder functions (such as ec_tell()) can
       operate on either one, simplifying code which uses both.
      The precision argument to ec_tell() has been removed.
      It now comes in two precisions:
        ec_tell() gives 1 bit precision in two operations, and
        ec_tell_frac() gives 1/8th bit precision in... somewhat more.
      ec_{enc|dec}_bit_prob() were removed (they are no longer needed).
      Some of the byte buffer access functions were made static and
       removed from the cross-module API.
      All of the code in rangeenc.c and rangedec.c was merged into
       entenc.c and entdec.c, respectively, as we are no longer
       considering alternative backends.
      rangeenc.c and rangede.c have been removed entirely.
      
      This passes make check, after disabling the modes that we removed
       support for in cf5d3a8c.

      Clean up some type usage. · 8fcde379
      Timothy B. Terriberry authored
      ec_byte_read() ec_byte_read_from_end() had different return types.
      ec_dec_bits() was storing its return value as int instead of
       ec_uint32, which will break if int is only 16 bits.

      Entropy coder clean-up. · 30df6cf3
      Timothy B. Terriberry authored
      This simplifies a good bit of the error handling, and should make it
       impossible to overrun the buffer in the encoder or decoder, while
       still allowing tell() to operate correctly after a bust.
      The encoder now tries to keep the range coder data intact after a
       bust instead of corrupting it with extra bits data, though this is
       not a guarantee (too many extra bits may have already been flushed).
      It also now correctly reports errors when the bust occurs merging the
       last byte of range coder and extra bits.
      
      A number of abstraction barrier violations were cleaned up, as well.
      This patch also includes a number of minor performance improvements:
       ec_{enc|dec}_bits() in particular should be much faster.
      
      Finally, tf_select was changed to be coded with the range coder
       rather than extra bits, so that it is at the front of the packet
       (for unequal error protection robustness).

      Implemented "raw bits" · c08be448
      Jean-Marc Valin authored
      Making it so all the information encoded directly with ec_enc_bits() gets
      stored at the end of the stream, without going through the range coder. This
      should be both faster and reduce the effects of bit errors.
