PR gold/12952 * resolve.cc (Symbol::override_base_with_special): Don't override the version if the overriding symbol has a different name. * dynobj.cc (Versions::add_def): Add dynpool parameter. Change all callers. If we give an error about an undefined version, define the base version if necessary. * dynobj.h (class Versions): Update declaration. * testsuite/weak_alias_test_5.cc: New file. * testsuite/weak_alias_test.script: New file. * testsuite/weak_alias_test_main.cc: Check that versioned_symbol and versioned_alias have the right value, and call t2. * testsuite/Makefile.am (weak_alias_test_DEPENDENCIES): Add weak_alias_test_5.so. (weak_alias_test_LDADD): Likewise. (weak_alias_test_5_pic.o, weak_alias_test_5.so): New targets. * testsuite/Makefile.in: Rebuild.
