Pentium Pro and above means at least i686. i586 is Pentium1 which is less featured. That means that you cant do much, however you can try to tune the i686 target and disable emiting of the instructions that were added from the Pentium Pro. Maybe that the produced instruction will then be compatible.
that would be something like `--mcpu=i686 --mattrs=-mmx,-sse` and maybe more to be sure.
Other things: "Registered Targets: ... " means that maybe the LDC developers could add the i586 target but did not consider useful to add this is old processor (e.g Pentium1). For that you should ask them if you can and how activate the target when you build ldc2 on your old Geode.
