X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=bd59560480cc4f43a4ba75dc827ba27bcebb92dd;hp=bd59560480cc4f43a4ba75dc827ba27bcebb92dd

Join common code in the stages of next_move()

Rewrite the MovePicker class using lambda expressions for move filtering.
Includes code style changes by @mcostalba.

Verified for speed, passed STC:
LLR: 2.95 (-2.94,2.94) [-3.00,1.00]
Total: 43191 W: 9391 L: 9312 D: 24488

This rewrite of MovePicker.cpp seems to trigger less random crashes on Ryzen
machines than the version in previous master (reported by Bojun Guo).

Closes https://github.com/official-stockfish/Stockfish/pull/1454

No functional change.
