Hi,

Oh no!, bad news for me. I am still running my two machines on AMD 
Athlon 64 X2. I love Arch, I do not want to leave it :( I am sure that 
lots of people are on the same position.

I am reply here since I am not a archdev anymore so I do not have access 
to gitlab.

Why no build with these flags for packages that really takes advantage 
of this?

Take care.
