Date: Sat Apr 26 21:25:18 2025 +0200 Timestamp: 1745695518 Use matching llvm-profdata when using multiple clang compilers in parallel, it is necessary to use a matching llvm-profdata, as the profile data format may change between versions. To use the proper llvm-profdata binary, the one in the same directory as the compiler is used. This allows for code like: ```bash echo "Compiling clang" for comp in clang++-11 clang++-12 clang++-13 clang++-14 clang++-15 clang++-16 clang++-17 clang++-18 clang++-19 clang++-20 do make -j profile-build CXX=$comp COMP=clang >& out.compile.$comp mv stockfish stockfish.$comp done ``` after installing the required versions with the automatic installation script (https://apt.llvm.org/) closes https://github.com/official-stockfish/Stockfish/pull/5958 No functional change see source |
