// 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.
