Replying to [comment:20 vbraun]:
> PS: `-mcpu` is a deprecated synonym for `-mtune`.
Nope, `-mcpu` selects the instruction set, while `-mtune` only affects
timing-specific choices (selection or reordering of instructions of that
subset); `-march=foo` is equivalent to `-mcpu=foo -mtune=foo`. (I don't
think that's changed recently, though `configure` supports `--with-arch-
NN=...` and `--with-tune-NN=...`, NN in {32, 64}.)

Should we cc Jeroen and delete the ticket from the wishlist wiki page?
