The -files changed/added by this patch are: - -README.686 -match.S - -The speedup that this patch provides varies, depending on whether the -compiler used to build the original version of zlib falls afoul of the -PPro's speed traps. My own tests show a speedup of around 10-20% at -the default compression level, and 20-30% using -9, against a version -compiled using gcc 2.7.2.3. Your mileage may vary. - -Note that this code has been tailored for the PPro/PII in particular, -and will not perform particuarly well on a Pentium. - -If you are using an assembler other than GNU as, you will have to -translate match.S to use your assembler's syntax.
