Re: Have you some experience / link about difference between Python builded with gcc and clang?

Oooohhh uff, I have to install latest clang... or better, compile it as I did for gcc. And I have to read the install docs to see if there's some trick to optimize it... and I have to read the docs of pyperformance too (I only used pyperf until now)... Oh well, tomorrow :-D On Mon, 2 Mar 2020
