            Bug ID: 42608
           Summary: llvm-cov does not demangle template instantiations
           Product: new-bugs
           Version: 8.0
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: thomas.braun at virtuell-zuhause.de

Consider the following template

```
template <typename T>
void DoStuff(T)
{
;
}
```

in the coverage report with -show-instantiations enabled and llvm-cxxfilt as
demangler I do get a properly demangled name for the function summary.

But the separate instantiations do not get demangled function names.

>From a very course look at the code it looks like that in [1] only the names of
the functions are feed into the demangler, but the instantion groups from [2]
are missed.
