/* Macros for compiler / platform specific features and build options.

   Build options are:
    * BROTLI_BUILD_32_BIT disables 64-bit optimizations
    * BROTLI_BUILD_64_BIT forces to use 64-bit optimizations
    * BROTLI_BUILD_BIG_ENDIAN forces to use big-endian optimizations
    * BROTLI_BUILD_ENDIAN_NEUTRAL disables endian-aware optimizations
    * BROTLI_BUILD_LITTLE_ENDIAN forces to use little-endian optimizations
    * BROTLI_BUILD_PORTABLE disables dangerous optimizations, like unaligned
      read and overlapping memcpy; this reduces decompression speed by 5%
    * BROTLI_BUILD_NO_RBIT disables "rbit" optimization for ARM CPUs
    * BROTLI_DEBUG dumps file name and line number when decoder detects stream
      or memory error
    * BROTLI_ENABLE_LOG enables asserts and dumps various state information
