ELF dynsyms Many ELF targets arrange to emit a number of section symbols in .dynsym for use by dynamic relocations. This happens before the dynamic relocations are output, and the need for those symbols determined. In most cases they are not needed. A proper analysis of the need for dynamic section symbols is target specific and tedious, so this patch just excludes them in the obvious case when no dynamic relocations are present. The patch also runs the new pr23161 and pr23162 tests on more targets. bfd/ * elf-bfd.h (struct elf_link_hash_table): Add "dynamic_relocs". * elflink.c (_bfd_elf_init_2_index_sections): Comment fix. (_bfd_elf_add_dynamic_entry): Set "dynamic_relocs". (_bfd_elf_link_renumber_dynsyms): Exclude all section symbols when "dynamic_relocs" is not set. * elfxx-mips.c (count_section_dynsyms): Likewise. ld/ * testsuite/ld-elf/readelf.exp: Delete DUMP and selection of variant ver_def.vd. * testsuite/ld-elf/ver_def-tic6x.vd: Delete. * testsuite/ld-elf/shared.exp: Run most pr23161 and pr23162 tests for linux, nacl and gnu targets. * testsuite/ld-mips-elf/mips-elf.exp: Set base_syms to 1. * testsuite/ld-elf/pr23161a.rd: Don't check reloc type. Allow any order of __bss_start, _edata and _end. * testsuite/ld-elf/pr23161b.rd: Don't check plt and dyn relocs. Allow and order of __bss_start, _edata and _end. * testsuite/ld-elf/pr23162.rd: Fail if __bss_start, _edata or _end relocs are present rather than testing for no relocations. * testsuite/ld-aarch64/gc-plt-relocs.d, * testsuite/ld-aarch64/ifunc-1-local.d, * testsuite/ld-aarch64/ifunc-1.d, * testsuite/ld-aarch64/ifunc-2-local.d, * testsuite/ld-aarch64/ifunc-2.d, * testsuite/ld-aarch64/ifunc-21.d, * testsuite/ld-aarch64/ifunc-3a.d, * testsuite/ld-arm/farcall-mixed-lib-v4t.d, * testsuite/ld-arm/farcall-mixed-lib.d, * testsuite/ld-arm/gc-hidden-1.d, * testsuite/ld-arm/tls-gdesc-got.d, * testsuite/ld-arm/tls-lib-loc.d, * testsuite/ld-arm/tls-longplt-lib.d, * testsuite/ld-arm/tls-thumb1.d, * testsuite/ld-cris/libdso-10.d, * testsuite/ld-cris/libdso-11.d, * testsuite/ld-cris/libdso-13b.d, * testsuite/ld-cris/libdso-14.d, * testsuite/ld-cris/libdso-15.d, * testsuite/ld-cris/pic-gc-72.d, * testsuite/ld-cris/pic-gc-73.d, * testsuite/ld-cris/tls-gc-71.d, * testsuite/ld-mips-elf/mips16-pic-4a.nd, * testsuite/ld-mips-elf/pic-and-nonpic-3a.dd, * testsuite/ld-mips-elf/pie-n32.d, * testsuite/ld-mips-elf/pie-n64.d, * testsuite/ld-mips-elf/pie-o32.d: Update for removed dynamic section symbols.
