0044 // NOTE:
0045 // ====
0046 //
0047 // - For reasons of speed all fast assembler decompressors (having '_fast'
0048 //   in their name) can access (write to) up to 3 bytes past the end of
0049 //   the decompressed ("dst") block. Data past the end of the compressed
0050 //   ("src") block is never accessed (read from).
0051 //   [ technical note: because data is transferred in 32-bit units ]
0052 //
0053 // - Please also see asm/i386/00README.TXT and doc/LZO.FAQ for more
0054 //   important details about the assembler versions.
