Bug ID: 19597
Summary: Visibility attribute ignored on variable templates
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
consider:
template <typename T> __attribute__((visibility("hidden"))) const int &x = 4;
template const int &x<void>;
codgen looks bad:
@_Z1xIvE = weak_odr constant i32* @_ZGR1xIvE, align 8
however, it works fine for non-static data members, their close relatives:
template <typename T> struct S {
__attribute__((visibility("hidden"))) static const int &x;
};
template <typename T> const int &S<T>::x = 4;
template const int &S<void>::x;
@_ZN1SIvE1xE = weak_odr hidden constant i32* @_ZGRN1SIvE1xE, align 8
