Hello,
Using Mac Intel Ventura 13.6 I upgrade to latest command line tools that provides clang 15.0.
Unfortunately the applications compiled with this last update are running 4 at 5 times SLOWER . Has any one the same observation ?
Here the command line :
g++ -Ofast -march=native -flto -funroll-loops -DNDEBUG -o a myprog.cpp
So I reverted to clang 13.0 to have an acceptable performance.
