As I was trying to replicate C++ behavior I've created a test case
ambiguous-anonymous-enum-lookup.cpp. And it results in diagnostics
clang/test/Modules/Output/ambiguous-anonymous-enum-lookup.cpp.tmp/test.cpp:6:10:
warning: ambiguous use of internal linkage declaration 'kAnonymousEnumValue'
defined in multiple modules [-Wmodules-ambiguous-internal-linkage]
return kAnonymousEnumValue;
^
clang/test/Modules/Output/ambiguous-anonymous-enum-lookup.cpp.tmp/include/textual.h:5:3:
note: declared here
kAnonymousEnumValue = 0,
^
clang/test/Modules/Output/ambiguous-anonymous-enum-lookup.cpp.tmp/include/textual.h:5:3:
note: declared here in module 'Piecewise.InitiallyHidden'
kAnonymousEnumValue = 0,
^
Is this warning correct or is it wrong and we have the same bug both in ObjC
and C++? I feel I am biased (and bad at C++ linkage rules), so need a separate
opinion on correctness.
