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