--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> --- https://gcc.gnu.org/g:6d5a6a26e28d15ac05f59ee4d3c3d7d4d42acac3 commit r14-11743-g6d5a6a26e28d15ac05f59ee4d3c3d7d4d42acac3 Author: Jakub Jelinek <ja...@redhat.com> Date: Wed May 15 18:50:11 2024 +0200 c++: Optimize in maybe_clone_body aliases even when not at_eof [PR113208] This patch reworks the cdtor alias optimization, such that we can create aliases even when maybe_clone_body is called not at at_eof time, without trying to repeat it in maybe_optimize_cdtor. 2024-05-15 Jakub Jelinek <ja...@redhat.com> Jason Merrill <ja...@redhat.com> PR lto/113208 * cp-tree.h (maybe_optimize_cdtor): Remove. * decl2.cc (tentative_decl_linkage): Call maybe_make_one_only for implicit instantiations of maybe in charge ctors/dtors declared inline. (import_export_decl): Don't call maybe_optimize_cdtor. (c_parse_final_cleanups): Formatting fixes. * optimize.cc (can_alias_cdtor): Adjust condition, for HAVE_COMDAT_GROUP && DECL_ONE_ONLY && DECL_WEAK return true even if not DECL_INTERFACE_KNOWN. (maybe_clone_body): Don't clear DECL_SAVED_TREE, instead set it to void_node. (maybe_clone_body): Remove. * decl.cc (cxx_comdat_group): For DECL_CLONED_FUNCTION_P functions if SUPPORTS_ONE_ONLY return DECL_COMDAT_GROUP if already set. * g++.dg/abi/comdat3.C: New test. * g++.dg/abi/comdat4.C: New test. (cherry picked from commit 6ad7ca1bb905736c0f57688e93e9e77cbc71a325)
