-march=native is really bad, and -mtune=native is also a problem due to e.g. breaking reproducibility, but I am not aware of any general "not OK" for -O3 in Debian. The Debian default is -O2, but many packages are also using -O3 and there is no strong reason against doing so if it is considered better for a specific package. > Kind regards, > Laurent Bigonville cu Adrian
