            Bug ID: 46522
           Summary: [DWARF] Template instance name not consistent with
                    CodeView.
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: DebugInfo
          Assignee: unassignedbugs at nondot.org

For the given test:

//----------------------------------------------------------

template<class U,class V>
struct S {
};

S<int, char> SS;

//----------------------------------------------------------

The name generated for the template instance, is not consistent between clang
(DWARF) and clang (CodeView), making search or compare difficult.

Clang (DWARF):     'S<int, char>'     <-- Added space
Clang (CodeView):  'S<int,char>'

GCC (DWARF):       'S<int, char>'
MSVC (CodeView):   'S<int,char>'

Clang (DWARF) adds a space between arguments.
Clang (CodeView) does not add any spaces.
