Hi all!
And now for some good news - after several small optimisations on the git
master and upgrading gcc to GCC-7.2.0-RC1 , the MS 32k benchmark of
freecell-solver on my Core i3 machine now runs below 6.10s - namely about 6.06s.
Note that the new GCC's PGO (= profile-guided optimisations) performance is
much worse than the one of the executables generated by cmake without it, but
it is better than the PGO performance of GCC-4.9.x which was the previous
record holder.
Regards,
Shlomi
