Dev Builds » 20180314-0031

You are viewing an old NCM Stockfish dev build test. You may find the most recent dev build tests using Stockfish 15 as the baseline here.

Use this dev build

NCM plays each Stockfish dev build 20,000 times against Stockfish 7. This yields an approximate Elo difference and establishes confidence in the strength of the dev builds.

Use intrinsics only for LSB/MSB The NO_BSF does not cover any real life use-case today. The only compilers that can compile SF today, with the current Makefile and no source code changes, are either GCC compatible (define __GNUC__) or MSVC compatible (define _MSC_VER). So they all support LSB/MSB intrinsics. This patch simplifies away the software fall-backs of LSB/MSB that were still in Stockfish code, but unused in any of the officially supported compilers. Note the (legacy) MSVC/WIN32 case, where we use a 32-bit BSF/BSR solution, as 64-bit intrinsics aren't available there. Discussed in: https://github.com/official-stockfish/Stockfish/pull/1447 and: https://github.com/official-stockfish/Stockfish/pull/1479 No functional change.
