Subject: new DES key setup
Hi,
JFYI, I am integrating the new DES key setup algorithm from
john-1.7.8-fast-des-key-setup-3 into the main tree. I've already
reimplemented it in a generic fashion (pure C, no intrinsics), which
still provides great speedup over the old code, and I wrote assembly
implementations for MMX, SSE2, x86-64/SSE2. This is already seen in
CVS. Now I need to re-add the intrinsics in a more generic fashion,
with macros for different kinds of intrinsics (not only SSE2).
It looks like AltiVec lacks simple shifts of vectors by constant number
of bits - I have to load another vector with shift counts first. %-)
The next step would be integrating OpenMP for DES in one official way,
getting rid of the -omp-des-4 vs. -omp-des-7 patches.
