Hi,
I am running Mac Intel I7 post 2020 with Sonoma and clang 15.0 .
The Clang 15.0 makes c++ code running 5 times slower than it was before upgrade from Ventura 13.6 and Clang 14.3.1
The other trouble is that Sonoma does not allow to revert to Clang 14.3.1 . I do not use Xcode only command line tools .
here my options :
g++ -std=c++17 -Ofast -march=native -funroll-loops -flto -DNDEBUG -o a prog.cpp
So what happened to C++ ?
