Subject: Revert "Use std::stable_sort() instead of std::sort()"
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=d6b04c27989bba77b23474f5b6f75974c7199644;hp=d6b04c27989bba77b23474f5b6f75974c7199644

Revert "Use std::stable_sort() instead of std::sort()"

Unfortunatly std::stable_sort() implementation in gcc is
horrendously slow. We have a big performance regression on
Linux systems (-20% !)

So revert the commit and wait to fix the issue in a different
way, perhaps with an our home grown sorting, that should be
comparable in speed with std::sort()
