Change the readelf and objdump programs so that they will automatically follow links to separate debug info files.
* configure.ac (follow-debug-links): Add option to enable or disable the following of debug links by default. Set the default for the option to be 'follow'. * dwarf.c (do_follow_links): Initialise with DEFAULT_FOR_FOLLOW_LINKS. (dwarf_select_sections_by_names): Add no-follow-links option. (dwarf_select_sections_by_letter): Add 'N' option. * objdump.c (usage): Add conditional text describing the follow links option. (slurp_symtab): Ensure that there is a NULL entry at the end of the symbol table. (slurp_dynamic_symtab): Likewise. (dump_bfd): When extending the symbol table, ensure that there is still a NULL entry at the end. * readelf.c (usage): Add conditional text describing the follow links option. * doc/binutils.texi: Update documentation for objcopy and readelf. * doc/debug.options.texi: Update documentation of the follow-links option. * config.in: Regenerate. * configure: Regenerate. * testsuite/binutils-all/compress.exp: Add the -WN option to objdump command lines that are not expecting to follow links. * testsuite/binutils-all/readelf.exp: Add the --debug-dump=no-follow-links option to tests that are not expecting to follow debug links. gas * testsuite/gas/mach-o/sections-1.d: Stop automatic debug link following. * testsuite/gas/xgate/insns-dwarf2.d: Likewise. ld * testsuite/ld-elf/sec64k.exp: Stop readelf from automatically following debug links.
