      get_bits: remove A32 variant · a1e98f19
      Mans Rullgard authored
      
      
      The A32 bitstream reader variant is only used on ARMv5 and for
      Prores due to the larger bit cache this decoder requires.
      
      In benchmarks on ARMv5 (Marvell Sheeva) with gcc 4.6, the only
      statistically significant difference between ALT and A32 is
      a 4% advantage for ALT in FLAC decoding.  There is thus no (longer)
      any reason to keep the A32 reader from this point of view.
      
      This patch adds an option to the ALT reader increasing the bit
      cache to 32 bits as required by the Prores decoder.  Benchmarking
      shows no significant change in speed on Intel i7.  Again, the
      A32 reader fails to justify its existence.
