           Summary: typeinfo is not demangled in error messages
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: pinskia at physics dot uc dot edu
                CC: gcc-bugs at gcc dot gnu dot org,gdr at gcc dot gnu dot
                    org

Code:
#include <typeinfo>
int get_uuidof( const std::type_info& inf );

template< class T ,int i = get_uuidof( typeid(T) ) >
struct TBoaz{
} ;

template TBoaz<int>;

Gives the following error: 

prnew10.cc:8: error: non-constant `get_uuidof(const std::type_info&)((&_ZTIi))' 
   cannot be used as template argument

Notice _ZTIi is not demangled to typeid(int).

--- Comment #2 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
Ideally, a port should not need to define reg_alloc_order; it's rather a blunt
instrument.

Better would be for the register allocator to have a better understanding of
which registers are being used for parameter passing in the current routine so
that it can pick from the remaining call-clobbered list.

In GCC 4.8.3, we get following error.

$ g++ foo.cpp
foo.cpp:4:50: error: call to non-constexpr function ‘int get_uuidof(const
std::type_info&)’
 template< class T ,int i = get_uuidof( typeid(T) ) >
                                                  ^

 template TBoaz<int>;
                   ^
foo.cpp:8:20: error: expected unqualified-id before ‘;’ token
 template TBoaz<int>;

So, we can simply close this issue, can't we?

I think I Know why this shows up this way, we lower typeid(T) very early on.

I agree on the confusing looking of the message.
However, we cannot omit the argument because it is the value of the
function that is being used.  What we can avoid, however, is getting
the mangled name.  I believe this is just another case of the
front-end being too eager.

I don't know what to do with this PR.  Demangling the typeid as part of
diagnostic messages would mean that now the demangler is part of the compiler,
which in some sense is unacceptable.  On the other hand, there should be room
for improvement.

does the rporter object to classifying this an enhancement, and nto a bug
proper?
