<pre>Created <span class=""><a href="attachment.cgi?id=17441" name="attach_17441" title="Code which repros the bug.">attachment 17441</a> <a href="attachment.cgi?id=17441&action=edit" title="Code which repros the bug.">[details]</a></span>
Code which repros the bug.
When compiling with either `-fvisibility=hidden` or
`-fvisibility-inlines-hidden`, templated class methods inside a templated class
do not respect the visibility attribute (e.g.
`__attribute__((visibility("default")))`) and remain hidden.
Repro code:
template<typename T>
class A {
int a;
public:
template<typename C>
__attribute__ ((visibility ("default")))
static void foo() {}
};
void func() {
A<int>::foo<int>();
}
Then run, on the above code:
$ clang -c -fvisibility=hidden -o test.o test.cpp
$ readelf -s test.o # shows `void A<int>::foo<int>()` is HIDDEN</pre>
