John the ripper has support for SSE2 instructions for some time now. These can be enabled during compilation by selecting the "linux-x86-sse2" profile.Currently the ebuild does not support this. Reproducible: Always Steps to Reproduce: 1.emerge -pv johntheripper 2.note the absence of the SSE2 use flag Actual Results: No SSE2 optimized john the ripper available :-( Expected Results: SSE2 optimization for john the ripper. Adding SSE2 support should be easy, as there is smimilar support for MMX. I can provide a patch for the ebuild if needed.
Thanks!
