Dev Builds » 20130901-1618

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.

Improve ARM compatibility STANDALONE-TOOLCHAIN.html in Android NDK says: It is recommended to use the -mthumb compiler flag to force the generation of 16-bit Thumb-1 instructions (the default being 32-bit ARM ones). If you want to target the 'armeabi-v7a' ABI, you will need ensure that the following two flags are being used: CFLAGS='-march=armv7-a -mfloat-abi=softfp' Note: The first flag enables Thumb-2 instructions, and the second one enables H/W FPU instructions while ensuring that floating-point parameters are passed in core registers, which is critical for ABI compatibility. Do *not* use these flags separately! Thanks to Peter Osterlund for pointout this doc and for showing me an example Makefile to follow. No functional change.
