When the versioned symbol foo is removed from the shared library, the ".symver foo,foo@VER" directive provides binary compatibility for foo@VER. In this case, the unversioned symbol foo should be hidden and shouldn't generate a multiple definition error. PR gold/31830 * resolve.cc (Symbol_table::resolve): Move symbol version handling to ... * symtab.cc (Symbol_table::add_from_object): Here. If the hidden version from .symver is the same as the default version from the unversioned symbol, don't make the unversioned symbol the default versioned symbol. * testsuite/Makefile.am (check_SCRIPTS): Add ver_test_pr31830.sh. (check_DATA): ver_test_pr31830_a.syms and ver_test_pr31830_b.syms. (ver_test_pr31830_a.syms): New. (ver_test_pr31830_b.syms): Likewise. (ver_test_pr31830_a.so): Likewise. (ver_test_pr31830_b.so): Likewise. * testsuite/Makefile.in: Regenerated. * testsuite/ver_test_pr31830.script: New file. * testsuite/ver_test_pr31830.sh: Likewise. * testsuite/ver_test_pr31830_a.c: Likewise. * testsuite/ver_test_pr31830_b.c: Likewise. * testsuite/ver_test_pr31830_lto.c: Likewise. * testsuite/ver_test_pr31830_lto.sh: Likewise.
