           Summary: Support optimized out / unused template methods
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jan.kratochvil@redhat.com


This is more a GCC extension request but we need to formulate it first.

#include <map>
int
main ()
{
  std::map <int, int> v { std::make_pair (1, 2) };
//  v.clear ();
  return v[1];
}

7      return v[1];
(gdb) p v.clear()
Cannot evaluate function -- may be inlined

after uncommenting the line in the source:

(gdb) p v.clear()
$1 = void

There should be for example some extra .text section in the separate .debug
info file containing all the unused methods for a template instance.
