Summary: warning flag for emission of vague linkage bits
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: bkoz@gcc.gnu.org
Request for -Wvague-linkage.
This flag would warn for the lack of key function, etc that makes
typeinfo/vtable information emitted in every TU for polymorphic classes
class regex_error
: public std::runtime_error
{
public:
explicit
regex_error(regex_constants::error_type __ecode)
: std::runtime_error("regex_error"), _M_code(__ecode)
{ }
regex_constants::error_type
code() const
{ return _M_code; }
protected:
regex_constants::error_type _M_code;
};
It's hard to scan through the libstdc++ sources for other places where
maintainers might want to know exact linkage. However, the compiler already
knows this.

Confirmed. I think a better name for the flag is -Wvague-linkage-class from
the way you are describing what you want for this flag is only for classes
which have vague linkage and not just functions which have vague linkage.
