Move elf32.em and elf-generic.em functions Many ELF linker targets support multiple "emulations" and thus have multiple copies of elf32.em being compiled and linked into ld. This patch moves much of elf32.em and elf-generic.em into files which will be compiled just once, resulting in a 20% decrease in ld size for --enable-targets=all. * Makefile.am (ALL_EMUL_EXTRA_OFILES): Add ldelf and ldelfgen. (CFILES, HFILES, EXTRA_ld_new_SOURCES): Likewise. * configure.tgt: Formatting. (targ_extra_ofiles): Init to ldelf.o ldelfgen.o, reset to just ldelfgen.o for generic ELF targets, and empty for non-ELF. * emultempl/aarch64elf.em (gldaarch64_layout_sections_again): Use ldelf_map_segments. (gld${EMULATION_NAME}_after_allocation): Likewise. (real_func, aarch64_for_each_input_file_wrapper), (aarch64_lang_for_each_input_file): Delete. (lang_for_each_input_file): Don't define. * emultempl/alphaelf.em (alpha_after_parse): Use ldelf_map_segments. * emultempl/armelf.em (gldarm_layout_sections_again): Likewise. (gld${EMULATION_NAME}_after_allocation): Likewise. (real_func, arm_for_each_input_file_wrapper), (arm_lang_for_each_input_file): Delete. (lang_for_each_input_file): Don't define. * emultempl/cr16elf.em (cr16elf_after_parse): Use ldelf_map_segments. * emultempl/crxelf.em (crxelf_after_parse): Likewise. Delete declaration. * emultempl/cskyelf.em (gldcsky_layout_sections_again): Use ldelf_map_segments. (gld${EMULATION_NAME}_after_allocation): Likewise. (real_func, csky_for_each_input_file_wrapper), (csky_lang_for_each_input_file): Delete. (lang_for_each_input_file): Don't define. * emultempl/genelf.em: Include ldelfgen.h. (gld${EMULATION_NAME}_before_allocation): Use ldelf_map_segments. * emultempl/hppaelf.em (hppaelf_after_parse): Likewise. (hppaelf_layout_sections_again): Likewise. (gld${EMULATION_NAME}_after_allocation): Likewise. (real_func, hppa_for_each_input_file_wrapper), (hppa_lang_for_each_input_file): Delete. (lang_for_each_input_file): Don't define. * emultempl/ia64elf.em (ia64elf_after_parse): Use ldelf_map_segments. * emultempl/m68hc1xelf.em (real_func), (m68hc11_for_each_input_file_wrapper), (m68hc11_lang_for_each_input_file): Delete. (lang_for_each_input_file): Don't define. * emultempl/metagelf.em (metagelf_layout_sections_again): Use ldelf_map_segments. (gld${EMULATION_NAME}_after_allocation): Likewise. (real_func, metag_for_each_input_file_wrapper), (metag_lang_for_each_input_file): Delete. (lang_for_each_input_file): Don't define. * emultempl/mipself.em (real_func), (mips_for_each_input_file_wrapper), (mips_lang_for_each_input_file): Delete. (lang_for_each_input_file): Don't define. * emultempl/mmo.em: Don't include elf-bfd.h, do include ldelfgen.h. (gld${EMULATION_NAME}_after_allocation): Use ldelf_map_segments. * emultempl/nds32elf.em (nds32_elf_after_parse): Use ldelf_after_parse. (nds32_elf_after_allocation): Comment fix. * emultempl/nios2elf.em (nios2elf_layout_sections_again): Use ldelf_map_segments. (gld${EMULATION_NAME}_after_allocation): Likewise. (real_func, nios2_for_each_input_file_wrapper), (nios2_lang_for_each_input_file): Delete. (lang_for_each_input_file): Don't define. * emultempl/ppc32elf.em (gld${EMULATION_NAME}_load_symbols): Delete declaration.

(ppc64_recognized_file): Call ldelf_load_symbols. * emultempl/riscvelf.em (gld${EMULATION_NAME}_after_allocation): Use ldelf_map_segments. * emultempl/spuelf.em (spu_place_special_section): Use ldelf_place_orphan. * emultempl/tic6xdsbt.em (gld${EMULATION_NAME}_after_allocation): Use ldelf_map_segments. * emultempl/vms.em: Include ldelfgen.h. (gld${EMULATION_NAME}_after_allocation): Use ldelf_map_segments. * emultempl/elf32.em: Remove unnecessary headers, include ldelf.h and ldelfgen.h. Move much of file content to.. * ldelf.c: ..here. New file. * ldelf.h: New file. * emultempl/elf-generic.em: Move gld${EMULATION_NAME}_map_segments.. * ldelfgen.c: ..to here. * ldelfgen.h: New file. * ldlang.c (lang_for_each_input_file): Adjust to only call func on real files. (lang_for_each_file): Likewise. * po/SRC-POTFILES.in: Regenerate. * Makefile.in: Regenerate.
