Bug ID: 27070
Summary: clang cannot distinguish declspec(property) of same
property name but with different types (T &, T const
&)
Product: clang
Version: 3.8
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: chen...@outlook.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
This happens on clang version 3.8.0-2ubuntu1 (tags/RELEASE_380/final)) on
xubuntu 16.04 beta, the code sample and compiler error is as follows. It is a
regression, since clang 3.6.2 could build this sample with no issue. Could you
please take a look? Thanks.
01 #include <iostream>
02 template <class T> class Foo {
03 public:
04 __declspec(property(get=get_Data)) T const& Data;
05 T const& get_Data() const { return data_; }
06 __declspec(property(get=get_Data)) T & Data;
07 T & get_Data() { return data_; }
08 private:
09 T data_;
10 };
11 void print(int const & val){ std::cout << val; }
12 int main(int argc, char** argv) {
13 Foo<int> foo;
14 print(foo.get_Data()); // compilation passed
15 print(foo.Data); // compilation failed
16 }
./foo.cpp:15:15: error: reference to 'Data' is ambiguous
print(foo.Data);
^
./foo.cpp:4:49: note: candidate found by name lookup is 'Foo<int>::Data'
__declspec(property(get=get_Data)) T const& Data;
^
./foo.cpp:6:44: note: candidate found by name lookup is 'Foo<int>::Data'
__declspec(property(get=get_Data)) T & Data;
