37Update:

39I've been ignoring these assembly routines for years, believing that
40gcc's generated code had caught up with it sometime around gcc 2.95
41and the major rearchitecting of the Pentium 4. However, I recently
42learned that, despite what I believed, this code still has some life
43in it. On the Pentium 4 and AMD64 chips, it continues to run about 8%
44faster than the code produced by gcc 4.1.

46In acknowledgement of its continuing usefulness, I've altered the
47license to match that of the rest of zlib. Share and Enjoy!
