// 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.
