Stockfish universal x64 build test

[j_romang]

I tried to build an universal stockfish x64 windows executable : https://db.tt/U1KrSWjZ
It should auto-detect your CPU at startup (x86-64, x86-64-modern, or x86-64-bmi2) so that you have the fastest stockfish running in an universal way. Please tell me if it works on your particular platform !

I got this (i7-2620M): "The program can't start because libgcc_s_sjlj-1.dll is missing from your computer."

Thanks Yolin, is just updated the exe in the link : can you try again ?

Works now!

Nice
You can check the detected version with the module name :

• Stockfish 140414 64 for the basic version
  Stockfish 140414 64 SSE 4.2 for the modern version
  Stockfish 140414 64 BMI2 for the haswell version

This i get on my i7 2670QM (1core)
It would be nice if we could get the source..so that i don't have to make 6 compiles every time
For sure very nice done!!

The source code is not modified ; it's just compiling/packing work (and it takes more time than making separate compiles ) If there is interest in this, I might also add 32 bit detection.

Sure,i think many people would be happy to see 32bit detection also!

If it's just compiling/packing work..you can just copy/paste these compiling lines in a file for next time..and of course i'am interested to try them myself if you are willing to share them!
Or put your idea on testframe..

I have no script yet to automate the process : I'll try to polish this an I will make it public
