Nice improvement. Thanks Lucas

I guess a non popcount compile for older 64 bit systems is out of reach (again)?

Congrats Lucas!

Guenther, I have tried to compile a version without the __builtin_popcountll. I have not removed the __builtin_ctzll and __builtin_clzll, which I expect you have support for. Let me know if the compile works.

Also, note that Lucas's program will crash if you do not follow the proper UCI spec, so make sure to issue ucinewgame if you are going to try running from the command line.

Thanks Lucas. Just in time for my next tournament.

Thanks a lot Andrew! Very helpful as always.

Edit:
Of course the main thanks goes to Lucas.

Actually you don't need to change the code. That's the beauty of compiler intrinsics. All you need is to use march=nocona (oldest Intel 64-bit, no popcnt) or march=k8 (oldest AMD 64-bit, no popcnt). So you'd modify the make.sh script to:

Code: Select all

W="-Wfatal-errors -Wall -Wextra -Wshadow"
O="-O3 -flto -march=nocona -DNDEBUG"
C="x86_64-w64-mingw32-gcc -static"  # Linux: clang/gcc, Windows: x86_64-w64-mingw32-gcc -static, Android: arm-linux-gnueabi-gcc -static
$C $VERSION -std=gnu11 $W $O -o $1 ./src/*.c -lpthread -lm -s
wine $1 search 12 1

then run: "./make.sh ./demolito.exe". The last line (bench command) assumes you have wine. You can skip this, of course, if you don't want to verify that the executable is working.

Thanks Andrew! This works for my [old] Intel Core2 Quad, 64-bit PC.
