This happens due to autoprofile pass makes edge make_speculative. Then ipa-devirt does the same with the same speculative_id which reults in duplicate speculative_id and ICE. during IPA pass: cp test.i:31:1: internal compiler error: verify_cgraph_node failed 0x39bfa6b internal_error(char const*, ...) ../../gcc/gcc/diagnostic-global-context.cc:787 0x13914eb cgraph_node::verify_node() ../../gcc/gcc/cgraph.cc:4454 0x13738ab symtab_node::verify() ../../gcc/gcc/symtab.cc:1377 0x1373d1b symtab_node::verify_symtab_nodes() ../../gcc/gcc/symtab.cc:1499 0x13a3653 symtab_node::checking_verify_symtab_nodes() ../../gcc/gcc/cgraph.h:718 0x182d267 symbol_table::remove_unreachable_nodes(_IO_FILE*) ../../gcc/gcc/ipa.cc:688 0x19f8c33 execute_todo ../../gcc/gcc/passes.cc:2163 We may also have to check if the speculative edge is present before making speculative. gcc/ChangeLog: 2025-12-22 Kugan Vivekanandarajah <kvivekananda@nvidia.com> * cgraph.cc (cgraph_edge::get_next_speculative_id): New. * cgraph.h (cgraph_edge::get_next_speculative_id): New. * ipa-devirt.cc (ipa_devirt): Use get_next_speculative_id in make_speculative.

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. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
