Libffm packaged for testing...
Good news for 21164 owners who want faster math than libm has provided
us: I've packaged Joachim Wesner's libffm and made it available for
testing on beezer. PLEASE please check this and let me know if it will
work. Here's the location:
Complete source and binary packages are available there (complete with
sig). Like I said, please test these and let me know how/if it works.
I'm still working on the package, so don't expect that to be the final
one yet, but once I get it knocked out, I'll upload it if I get good
Oh, for those of you who are unfamiliar with libffm (announced on the
redhat list), it's a library that replaces some of the functions contained
in libm with optimised versions (optimised for the 21164, but should work
on UDBs at the same speed...from what I can tell here). To use it, just
link libffm to your binaries BEFORE linking libm (ie. -lffm -lm).
Benchmarking of this would be appreciated, btw....
