This file seems interesting:

compiler-rt/lib/sanitizer_common/sanitizer_symbolizer_itanium.cc

It seems there is a demangler already accessible in modern C++ ABI 
libraries. What about providing a demangling interface that uses the C++ 
itanium demangler as default (if available), falls back to just return 
the function name if no demangler is available and finally allows the 
frontend to provide its own demangler?

Cheers,
Tobi
