* elf.c (_bfd_elf_find_segment_containing_section): New function:
Scan the segment map looking for the segment containing a specified function. * elf-bfd.h: Prototype the new function. * elf-hppa.h (elf_hppa_osec_to_segment): Delete. (elf_hppa_record_segment_addrs): Use new function. * elf32-bfin.c (_bfdfdpic_osec_to_segment): Use new function. * elf32-frv.c (_frvfdpic_osec_to_segment): Use new function. * elf32-hppa.c (hppa_record_segment_addr): Use new function. * elfxx-ia64.c (elfNN_ia64_relocate_section): Use new function.
