GCC 5.0 works on Windows for me now

Post by Dann Corbit »

Previous builds would crash and burn somewhere whenever I tried to actually use them to do something useful.

Specifically:
gcc-5.0-win64_5.0.0-20150209.7z
worked fine for me. I did a build and test with Stockfish and it looks good.

Is your binary faster than with other compilers?

I don't know if mine is faster. I have to make a few little tweaks to Stockfish so that it will do what I want. For instance, I turn off the noise of reporting fail high and fail low, and I also write an EPD record to disk for completed iterations of 25 ply or more.

Here is the output from 4.9.3:

You can't really tell anything about faster from one search like this.
It will take an overnight run before I find whether or not it makes a positive difference.

Either way, I like to play with a new toy. If LLVM were reliable under Mingw, I would be playing with that too, even though it is a little slower than GCC.

I have not tried the latest LLVM in a while, maybe I will give it a shot also.

If anybody wants to try my version there is a copy of it here:
https://www.dropbox.com/s/zi37qv4zyipow ... c5.7z?dl=0

Keep in mind that it writes to disk by default, so you will probably want to turn the UCI logging feature off.

It also does not display fail high or fail low by default.
In my opinion, that is the only sensible default.

You can't really tell anything about faster from one search like this.
It will take an overnight run before I find whether or not it makes a positive difference.

Either way, I like to play with a new toy. If LLVM were reliable under Mingw, I would be playing with that too, even though it is a little slower than GCC.

I have not tried the latest LLVM in a while, maybe I will give it a shot also.
Just so you know, you have a MAJOR problem. The node counts are not matching for the same search depths. If this is using multiple threads, then they should not match. But in that case, I would run a similar test using just one CPU, where they should match exactly.

Re: GCC 5.0 works on Windows for me now

Post by Dann Corbit »

Run with 11 threads, and also the king safety was changed from floating point math to integer math.

This patch was applied to the new version:
Author: hxim

Timestamp: 1423519355

Fix KingDanger[] array initialization

Use integer arithmetic instead of floating point arithmetic.
Floating point arithmetic was causing different results for some 32-bit compiles

No functional change
