PR c++/42317 * cgraph.h (struct cgraph_node): Add same_comdat_group field. * cgraph.c (cgraph_remove_node): Unchain node from same_comdat_group circular list. (cgraph_node_can_be_local_p): Return false for DECL_COMDAT with node->same_comdat_group. * ipa.c (cgraph_remove_unreachable_nodes): For any reachable node mark all its same_comdat_group nodes as also reachable. (cgraph_externally_visible_p): Return true even if any of same_comdat_group nodes has address taken. * lto-cgraph.c (lto_output_node): Stream out same_comdat_group. (output_cgraph): Ensure other same_comdat_group nodes are also included. (input_node): Stream in same_comdat_group. (input_cgraph_1): Fix up same_comdat_group fields from references to pointers. * cgraphunit.c (cgraph_analyze_functions): Mark all other same_comdat_group nodes as reachable. (cgraph_mark_functions_to_output): For each node->process process also other same_comdat_group nodes. * ipa-inline.c (cgraph_clone_inlined_nodes): Don't reuse nodes with same_comdat_group non-NULL. (cgraph_mark_inline_edge): Likewise. * decl2.c (cp_write_global_declarations): Clear DECL_EXTERNAL also on all other functions in the same comdat group. * optimize.c (maybe_clone_body): Also optimize virtual implicit dtors. For virtual comdat dtors tell cgraph that base and deleting dtor are in the same comdat group. * config/abi/pre/gnu.ver: Don't export certain base dtors that weren't previously exported. * g++.dg/opt/dtor2.C: New test. * g++.dg/opt/dtor2.h: New file. * g++.dg/opt/dtor2-aux.cc: New file.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
