  42 // i386 assembly decompressors
  43 //
  44 // NOTE:
  45 // ====
  46 //
  47 // - For reasons of speed all fast assembler decompressors (having '_fast'
  48 //   in their name) can access (write to) up to 3 bytes past the end of
  49 //   the decompressed ("dst") block. Data past the end of the compressed
  50 //   ("src") block is never accessed (read from).
  51 //   [ technical note: because data is transferred in 32-bit units ]
  52 //
  53 // - Please also see asm/i386/00README.TXT and doc/LZO.FAQ for more
  54 //   important details about the assembler versions.
