The machinery to do this was there, but not enabled if the terminator was the only thing in the section. bfd/ * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Don't exit early for a section containing just a terminator. Allow multiple terminators at end of section. * elflink.c (bfd_elf_discard_info): Iterate over .eh_frame sections when not adding alignment. Assert on terminator in the middle of FDEs. ld/ * testsuite/ld-elf/eh3.d: Update. * testsuite/ld-elf/eh4.d: Update.
