Cool.

That's an interesting question. I think that ideally we would like
-mieee to become the default when using gccgo. Users could still use
-mno-ieee (well, they could if there were such an option) but it seems
that for Go -mieee ought to be on by default. I'm not sure whether it
would be more appropriate to do that in code in gcc/go or in code in
gcc/config/alpha.
In gcc/go it would require some sort of #ifdef, or a new target hook.
In gcc/config/alpha one approach would be defining DRIVER_SELF_SPECS in
alpha.h with %{.go:-mieee}.
Thoughts?
