Commit ID d1e17989b51f220629e4e81a4bf413974f4b18e2
Author Sebastian Buchwald
Date 2023-03-14 07:25:14 UTC
Fix Makefile for clang 16 The clang 16 release will remove the -fexperimental-new-pass-manager flag (see https://github.com/llvm/llvm-project/commit/69b2b7282e92a1b576b7bd26f3b16716a5027e8e). Thus, the commit adapts the Makefile to use this flag only for older clang versions. closes https://github.com/official-stockfish/Stockfish/pull/4437 No functional change
