  57 // i386 assembly decompressors
  58 //
  59 // NOTE:
  60 // ====
  61 //
  62 // - For reasons of speed all fast assembler decompressors (having '_fast'
  63 //   in their name) can access (write to) up to 3 bytes past the end of
  64 //   the decompressed ("dst") block. Data past the end of the compressed
  65 //   ("src") block is never accessed (read from).
  66 //   [ technical note: because data is transferred in 32-bit units ]
  67 //
  68 // - Please also see asm/i386/00README.TXT and doc/LZO.FAQ for more
  69 //   important details about the assembler versions.
