* elf-bfd.h: Formatting. (_bfd_elf_map_sections_to_segments): Declare. * elf-eh-frame.c (_bfd_elf_discard_section_eh_frame_hdr): Don't clear program_header_size. * elf.c (get_program_header_size): Move. Don't use or set saved program_header_size here. (elf_modify_segment_map): New function. Split out from.. (assign_file_positions_for_load_sections): ..here. Assert header size is correct. Remove dead code. (_bfd_elf_map_sections_to_segments): Rename from map_sections_to_segments. Make global. Use get_program_header_size when we need estimate of header size. Call elf_modify_segment_map. Set program_header_size. (print_segment_map): Delete. (_bfd_elf_sizeof_headers): If segment_map available, get the actual size. * elf32-arm.c (elf32_arm_symbian_modify_segment_map): Make safe for calling more than once. * elf32-bfin.c (elf32_bfinfdpic_modify_segment_map): Likewise. * elf32-frv.c (elf32_frvfdpic_modify_segment_map): Likewise. * elfxx-mips.c (_bfd_mips_elf_modify_segment_map): Likewise. * elf32-i370.c (elf_backend_add_symbol_hook): Delete. (elf_backend_additional_program_headers): Delete. (elf_backend_modify_segment_map): Delete. * elf64-hppa.c (elf64_hppa_modify_segment_map): Convert to ISO C. * elfxx-ia64.c (elfNN_ia64_modify_segment_map): Likewise. * doc/bfdint.texi: Delete SIZEOF_HEADERS difficulties. ld/ * Makefile.am (ELF_DEPS): Define. Use in emul file deps. Fix many ELF emul file deps that incorrectly said they needed elf32.em instead of generic.em. Add genelf.em as required. * Makefile.in: Regenerate. * ldlang.c (lang_process): Call ldemul_finish before lang_check_section_addresses. * emulparams/arcelf.sh: Generic elf target needs genelf. * emulparams/d30v_e.sh: Likewise. * emulparams/d30v_o.sh: Likewise. * emulparams/d30velf.sh: Likewise. * emulparams/elf32_dlx.sh: Likewise. * emulparams/elf32_i860.sh: Likewise. * emulparams/elf32fr30.sh: Likewise. * emulparams/elf32frv.sh: Likewise. * emulparams/elf32iq10.sh: Likewise. * emulparams/elf32iq2000.sh: Likewise. * emulparams/elf32mt.sh: Likewise. * emulparams/mn10200.sh: Likewise. * emulparams/or32.sh: Likewise. * emulparams/or32elf.sh: Likewise. * emulparams/pjelf.sh: Likewise. * emulparams/msp430all.sh: Likewise. Extract common entries. * emulparams/pjlelf.sh: Include pjelf.sh. * emulparams/elf32frvfd.sh (EXTRA_EM_FILE): Unset. * emulparams/mn10300.sh (EXTRA_EM_FILE): Unset. * emultempl/elf-generic.em: New file. * emultempl/genelf.em: New file. * emultempl/elf32.em: Include elf-generic.em.

(gld${EMULATION_NAME}_finish): Rename from hppaelf_finish. Call gld${EMULATION_NAME}_map_segments. (LDEMUL_FINISH): Update. * emultempl/mmo.em: Correct comment. Include elf-bfd.h and source elf-generic.em. (mmo_finish): Call gld${EMULATION_NAME}_map_segments. * emultempl/ppc64elf.em (ppc_layout_sections_again): Likewise. (gld${EMULATION_NAME}_finish): Rename from ppc_finish. Call gld${EMULATION_NAME}_map_segments. (LDEMUL_FINISH): Update. ld/testsuite/ * ld-elf/eh1.d: Update for fewer program headers. * ld-elf/eh2.d: Likewise. * ld-elf/eh3.d: Likewise.
