<pre>
    Tools like `llvm-cxxfilt` or other llvm tools that support demangling like `llvm-readelf` won't demangle fixed point types. Clang supports mangling them but it would be really helpful for llvm tools to demangle them. The mangling rules under the Itanium C++ ABI for fixed point types are at https://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling-builtin.

https://github.com/PiJoules/llvm-project/pull/1/ is a WIP patch that someone can ressurect and land but it'll need some tests before landing.
