Arch Linux

I would like to have the possibility to have a better specification of the system architecture for packaging.

I cannot build a package with -march=native as people downloading the package from the repo can't know whether their pc supports this package.


My suggestion: extend package archs from (x86_64, i686) to all of the possible -mtune/-march options.
Also we will need a architecture dependency tree so pacman knows it can install the package and it will work.


If this is implemented in pacman, a repo can contain multiple target architectures of a single package, and pacman autoselects the best for it's host.
