Bug #: 55275
Summary: abi_tag attribute doesn't work on explicit
specializations of class templates
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: redi@gcc.gnu.org
CC: jason@gcc.gnu.org
This doesn't compile:
template<typename T>
struct __attribute ((abi_tag("cxx11"))) Foo
{
int f();
};
template<>
struct
__attribute ((abi_tag("cxx11")))
Foo<int>
{
int f();
};
int main()
{
Foo<int> f;
f.f();
}
abi.cc:10:1: error: redeclaration of ‘struct Foo<int>’ adds abi tag "cxx11"
Foo<int>
^
abi.cc:2:41: note: previous declaration here
struct __attribute ((abi_tag("cxx11"))) Foo
^
If I remove the attribute from the specialization then it compiles but the name
of the specialization doesn't include the abi_tag:
U _ZN3FooIiE1fEv
I want to use this with std::future which has explicit specializations.

I agree this is a bug, but I still don't think you need to tag future, since
it's new in C++11.

Yep, I filed this before your reply on the list. I'm happy to change <future>
without using the tag, I was just being (maybe too) cautious about ABI changes.
Thanks.
