--- Comment #2 from Arsen Arsenović <arsen at gcc dot gnu.org> ---
GNU targets, and many non-GNU targets, support ifuncs. you can use those to
resolve to an optimized implementation of a function.
if you mean to have gcc compile to a few -march/-mtune configurations and
generate these ifuncs 'implicitly', I suppose that could be done, and then
this'd be an RFE
