[Bug ada/46922] New: Missing exported symbols from libstdc++

           Summary: Missing exported symbols from libstdc++
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jakub@gcc.gnu.org
                CC: bkoz@gcc.gnu.org


In GLIBCXX_3.4.14 _ZSt25__throw_bad_function_callv symbol has been added, but
no other bad_function_call symbols (destructors, vtable/rtti).  I think even
those should be exported (of course with the current symver instead of the 4.5
one).

Also, the max_digits10 exports added in the same symver export a long double
symbol, so there should be also an *e* alias to the *d* symbol exported
under a new symver, as GLIBCXX_LDBL_3.4.14 doesn't exist, I guess it can be
added in gcc 4.6 without problems.  Also, it would be good to look at all other
recent additions, if any new symbols have long double in their mangled names
and handle them similarly.

Jakub, I'll commit momentarily the fix for std::bad_function_call. Can you take
care of the max_digits10 vs long double thing? You know it much better than me
and I don't know how to test the change. Patch pre-approved of course.

Hey P, why was bad_function_call added in CXXABI instead of GLIBCXX? That
doesn't make sense to me.

Uhhhm, you are right, doesn't make much sense, I don't know what i was
thinking. Luckily we are still in time to move those lines in gnu.ver. Let me
know if you want me to do it or you have the tweak part of other work.

By the way, it's not at all clear to me why those misplaced patterns actually
do the exporting work (of course at least I verified that, at the time).
