--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:0c45820ead85b8bc6f8283f7692a85d0c12ded4f commit r11-9983-g0c45820ead85b8bc6f8283f7692a85d0c12ded4f Author: Jason Merrill <ja...@redhat.com> Date: Tue Apr 12 16:40:14 2022 -0400 c++: local function versioning [PR104669] There were two problems with this testcase: we weren't copying the target attribute from the second declaration to the global alias for the first one (duplicate_decls hunk), and then we were treating the third one as matching the earlier one even though both are versioned (decls_match hunk). The latter change required a fix to find_last_decl (used for attribute mismatch warnings) to give up if we see a versioned function, as in that case we can't determine whether the decls match, because we are still in the process of setting the attributes on the new decl. PR c++/104669 gcc/cp/ChangeLog: * decl.c (decls_match): Compare versions even if not recording. (duplicate_decls): Propagate attributes to alias. * decl2.c (find_last_decl): Give up if versioned. gcc/testsuite/ChangeLog: * g++.target/i386/mv31.C: New test.
