37 | Update: | ||
38 | |||
39 | I've been ignoring these assembly routines for years, believing that | ||
40 | gcc's generated code had caught up with it sometime around gcc 2.95 | ||
41 | and the major rearchitecting of the Pentium 4. However, I recently | ||
42 | learned that, despite what I believed, this code still has some life | ||
43 | in it. On the Pentium 4 and AMD64 chips, it continues to run about 8% | ||
44 | faster than the code produced by gcc 4.1. | ||
45 | |||
46 | In acknowledgement of its continuing usefulness, I've altered the | ||
47 | license to match that of the rest of zlib. Share and Enjoy! | ||
