Discard zero address range eh_frame FDEs These are useless because they can't match any address. In fact, worse than useless because the .eh_frame_hdr lookup table matching addresses to FDEs does not contain information about the FDE range. The table is sorted by address; Range is inferred by the address delta from one entry to the next. So if a zero address range FDE is followed by a normal non-zero range FDE for the same address, everything is good. However, the qsort could just as easily sort the FDEs in the other order, in which case the normal FDE would effectively be seen to have a zero range. bfd/ PR 17447 * elf-bfd.h (struct eh_cie_fde): Comment re NULL u.fde.cie_inf. * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Mark zero address range FDEs for discarding.
