Lu <hjl.to...@gmail.com> Date: Mon Jul 28 12:16:11 2025 -0700 i386: Add GLIBC_ABI_GNU_TLS version [BZ #33221] Add the --gnu-tls-tag option to x86-64 ELF linker to add the GLIBC_ABI_GNU_TLS version dependency in output programs and shared libraries when linking against glibc if input relocatable object files call ___tls_get_addr. The output will fail to load and run at run-time against glibc which doesn't define the GLIBC_ABI_GNU_TLS version. Add the --enable-gnu-tls-tag configure option to enable --gnu-tls-tag by default. If unspecified, linker will add the GLIBC_ABI_GNU_TLS version dependency if input call ___tls_get_addr and libc.so defines the GLIBC_ABI_GNU2_TLS version. bfd/ PR ld/33287 * elf-linker-x86.h (elf_linker_x86_params): Add gnu_tls_version_tag. * elf32-i386.c (elf_backend_add_glibc_version_dependency): Add GLIBC_ABI_GNU_TLS support. * elfxx-x86.c (_bfd_x86_elf_link_check_relocs): Set has_tls_get_addr_call to 1 if ___tls_get_addr is used. * elfxx-x86.h (elf_x86_link_hash_table): Add has_tls_get_addr_call. ld/ PR ld/33287 * Mention --gnu-tls-tag, --no-gnu-tls-tag and --enable-gnu-tls-tag. * config.in: Regenerated. * configure: Likewise. * configure.ac: Add --enable-gnu-tls-tag. * ld.texi: Document --gnu-tls-tag and --enable-gnu-tls-tag. * ldlex.h (option_values): Add OPTION_GNU_TLS_VERSION_TAG and OPTION_NO_GNU_TLS_VERSION_TAG. * emultempl/elf-i386-glibc.em (elf_i386_glibc_before_parse): Initialize params.gnu_tls_version_tag.
