/* FIXME: x32 is very strange in its use of 64-bit relocation types in
 * a 32-bit environment. As long as the memory at reloc_addr is
 * zero-filled prior to relocations, just treating 64-bit relocations
 * as operating on 32-bit slots should be fine, but this should be
 * checked. In particular, R_X86_64_64, R_X86_64_DTPOFF64, and
 * R_X86_64_TPOFF64 may need checking. */
