-; FIXME:
-; The C1 direction is incorrect.
-; When moving an alias to an existing module and we want to discard the aliasee
-; (the C2 case), the IRMover knows to copy the aliasee as internal.
-; When moving a replacement to an aliasee to a module that has an alias (C1),
-; a replace all uses with blindly changes the alias.
-; The C1 case doesn't happen when using a system linker with a plugin because
-; the linker does full symbol resolution first.
-; Given that this is a problem only with llvm-link and its 1 module at a time
-; linking, it should probably learn to changes the aliases in the destination
-; before using the IRMover.
