This changes some ELF osabi tag-sniffing functions to avoid bfd_map_over_sections, in favor of iteration. I could only readily test the generic one. gdb/ChangeLog 2020-09-19 Tom Tromey <tom@tromey.com> * osabi.h (generic_elf_osabi_sniff_abi_tag_sections): Update. * osabi.c (generic_elf_osabi_sniff_abi_tag_sections): Change parameters. (generic_elf_osabi_sniffer): Use foreach. * mips-sde-tdep.c (mips_sde_elf_osabi_sniffer): Use foreach. * arm-tdep.c (arm_elf_osabi_sniffer): Use foreach.
