--export-dynamic-symbol-list is like a dynamic list, but without the symbolic property for unspecified symbols. When creating an executable, --export-dynamic-symbol-list is treated like --dynamic-list. When creating a shared library, it is treated like --dynamic-list if -Bsymbolic or --dynamic-list are used, otherwise, it is ignored, so that references to matched symbols will not be bound to the definitions within the shared library. PR ld/25910 * NEWS: Mention --export-dynamic-symbol[-list]. * ld.texi: Document --export-dynamic-symbol[-list]. * ldgram.y: Pass current_dynamic_list_p to lang_append_dynamic_list. * ldlang.c (current_dynamic_list_p): New. (ang_append_dynamic_list): Updated to take a pointer to struct bfd_elf_dynamic_list * argument instead of using link_info.dynamic_list. (lang_append_dynamic_list_cpp_typeinfo): Pass &link_info.dynamic_list to ang_append_dynamic_list. (lang_append_dynamic_list_cpp_new): Likewise. * ldlang.h (current_dynamic_list_p): New. (lang_append_dynamic_list): Add a pointer to struct bfd_elf_dynamic_list * argument. * ldlex.h (option_values): Add OPTION_EXPORT_DYNAMIC_SYMBOL and OPTION_EXPORT_DYNAMIC_SYMBOL_LIST. * lexsup.c (ld_options): Add entries for OPTION_EXPORT_DYNAMIC_SYMBOL and OPTION_EXPORT_DYNAMIC_SYMBOL_LIST. (parse_args): Handle --export-dynamic-symbol and --export-dynamic-symbol-list. * testsuite/ld-dynamic/export-dynamic-symbol-1.d: New. * testsuite/ld-dynamic/export-dynamic-symbol-2.d: New. * testsuite/ld-dynamic/export-dynamic-symbol-glob.d: New. * testsuite/ld-dynamic/export-dynamic-symbol-list-1.d: New. * testsuite/ld-dynamic/export-dynamic-symbol-list-2.d: New. * testsuite/ld-dynamic/export-dynamic-symbol-list-glob.d: New. * testsuite/ld-dynamic/export-dynamic-symbol.exp: New. * testsuite/ld-dynamic/export-dynamic-symbol.s: New. * testsuite/ld-dynamic/foo-bar.list: New. * testsuite/ld-dynamic/foo.list: New. * testsuite/ld-dynamic/foo.s: New. * testsuite/ld-dynamic/fstar.list: New. * testsuite/ld-elf/dlempty.list: New. * testsuite/ld-elf/shared.exp: Add tests for --export-dynamic-symbol and --export-dynamic-symbol-list. |

README
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
