// These have to use local relocations. Since that uses an offset into the
// section in x86_64 (as opposed to a scattered relocation), and since the
// linker can only decode this to an atom + offset by scanning the section,
// it is not possible to correctly encode these without SIGNED<N>. This is
// ultimately due to a design flaw in the x86_64 relocation format, it is
// not possible to encode an address (L<foo> + <constant>) which is outside the
// atom containing L<foo>.
