--- Comment #13 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:6ee5892638526366fc3d8a1f4426f3cc278ea061 commit r12-7752-g6ee5892638526366fc3d8a1f4426f3cc278ea061 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Mar 22 11:02:31 2022 +0100 lto-plugin: Use GNU ld or Solaris ld version script in preference to -export-symbols-regex [PR102426] As reported, libtool -export-symbols-regex doesn't work on Solaris when using GNU ld instead of Sun ld, libtool just always assumes Sun ld. As I'm unsure what is the maintainance status of libtool right now, this patch solves it on the lto-plugin side instead, tests at configure time similar way how libssp and other target libraries test for symbol versioning (except omitting the symbol version because we just want one GLOBAL symbol and rest of them LOCAL), and will use the current way of -export-symbols-regex onload as fallback when this doesn't work. 2022-03-22 Jakub Jelinek <ja...@redhat.com> PR lto/102426 lto-plugin/ * configure.ac (LTO_PLUGIN_USE_SYMVER, LTO_PLUGIN_USE_SYMVER_GNU, LTO_PLUGIN_USE_SYMVER_SUN): New test for symbol versioning support. * Makefile.am (version_arg, version_dep): Set conditionally based on LTO_PLUGIN_USE_SYMVER*. (liblto_plugin_la_LDFLAGS): Use $(version_arg) instead of -export-symbols-regex onload. (liblto_plugin_la_DEPENDENCIES): Depend on $(version_dep). * lto-plugin.map: New file. * configure: Regenerated. * Makefile.in: Regenerated.
