And I have forgotten how I hated Windows for a programmer.

If I were a programmer I would probably also hate Windows. But I am not.

However, this line worked: clang++ *.cpp -std=c++20 -O3 -march=native -oPetrel_2.1-x64.exe

PGO build does not add much speed for my code, but LTO does.

You mean I should add '-flto' to the command line?

I suggest it if it works without much extra trouble.

Clang does not like it.

Anyway, it seems the hash problem has gone so I'm going to start its test tomorrow.

Thank you very much.

Nevertheless, I suggest you offer Windows exes for download. I am sure all testing groups and most individuals have only Windows machines.
