But it's actually FAIL: base class (¶m)->a FAIL: base class (¶m)->x FAIL: inherited class (¶m)->a FAIL: inherited class (¶m)->x FAIL: continue to enums2 now. > gdb.c++/demangle.exp > | F |: gnu: >__thunk_64__0RL__list__Q29CosNaming20_proxy_NamingContextUlRPt25_CORBA_Unbounded_Sequence1ZQ29CosNaming7BindingRPQ29CosNaming15BindingIterator I claim this can't be unambiguously demangled, as it has more than one legal demangling. This will have to be marked XFAIL. I'll add more tests that break the demangler before i fixed it, to show this is worth it (I know it's worth it. Before, customers complained about things not being able to be demangled. Now, they don't). > > gdb.c++/namespace.exp > | F |: print 'AAA::xyzq'('x') > | F |: print 'BBB::CCC::xyzq'('x') > Unreproducable. I get "FAIL: info func xyzq" instead, but it's clearly not failing. info func xyzq^M All functions matching regular expression "xyzq":^M ^M File ./gdb.c++/namespace.cc:^M int AAA::A_xyzq(int);^M char AAA::xyzq(char);^M int BBB::B_xyzq(int);^M char BBB::CCC::xyzq(char);^M char BBB::Class::xyzq(char);^M char BBB::xyzq(char);^M All of these properly match xyzq. > gdb.c++/templates.exp > | F |: print t5i.value() I can only reproduce under stabs It looks like a name gets demangled properly the firsttime, when we print it the second, it's garbage. This tells me it's a method stub problem, and i'm on it. Under dwarf2 i get no failures at all. --Dan
