My impression was that is a compile time thing. IOW, if I tell the
compiler to enable i686 code generation, it might omit opcodes that are
not available on earlier processors.

I think that the position we should take is that if you want that level
of optimization, compile it yourself. If you are making a gem for
general distribution, compile it at a i386 level for broad
