Bug #: 54948
Summary: template unnecessarily displayed as "A<
template-parameter-1-1 >" not "A<T>"
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: enhancement
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: r...@gcc.gnu.org
template<typename> struct A;
template<typename T> struct A { A(Y); };
A<int> a;
This invalid code produces:
tp.cc: In instantiation of 'struct A<int>':
tp.cc:5:8: required from here
tp.cc:3:36: error: 'A< <template-parameter-1-1> >::Y' has incomplete type
template<typename T> struct A { A(Y); };
^
tp.cc:3:29: error: declaration of 'struct A<int>'
template<typename T> struct A { A(Y); };
^
This is correct, but "A< <template-parameter-1-1> >::Y" is rather ugly.
At the point of the error the parameter has a name, so "A<T>::Y" could be shown
instead.
