Using functions with attribute error/warning from templates doesn't
output the instantiation stack. With attribute deprecated this works.
Consider this program:
/////////////////////////////////////////////////////////////////
void func() __attribute__ ((error("error")));
//void func() __attribute__ ((warning("warning")));
//void func() __attribute__ ((deprecated));
void func()
{}
template<class T>
void bar()
{
func();
}
int main( int, char** )
{
bar<int>();
}
/////////////////////////////////////////////////////////////////
With attribute error:
t.cc: In function 'void bar() [with T = int]':
t.cc:11: error: call to 'func' declared with attribute error: error
With attribute deprecated:
t.cc: In function 'void bar() [with T = int]':
t.cc:16: instantiated from here
t.cc:11: warning: 'void func()' is deprecated (declared at t.cc:5)

Summary: attribute error and warning dont show the instantiation
