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: [email protected]

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.
