I'm also just going to leave this here.

From here:

Despite appearing as a the quintessential systemd fanboy, the real pattern seems to be Debian fanboyism.

My favourite part was saying how much of a good idea it was for Debian to drop support for certai arches because -march=i586 has real performance benefits over i386. This coming from the same person who calls -march=native completely useless at another point and saying the performance benefits don't exist because that's something Debian doesn't do.

From here:

Dropping aupport for older i386 CPUs makes sense because with -mcpu=i686, the compiler creates better and faster code.

From here:

Let me guess, you are a Gentoo user who is still believing the myth that building your packages with "-O3 -mnative" will actually make a huge difference.
