The current naming scheme adds the `dfs$` prefix to all DFSan-instrumented functions. This breaks mangling and prevents stack trace printers and other tools from automatically demangling function names. This new naming scheme is mangling-compatible, with the `.dfsan` suffix being a vendor-specific suffix: https://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling-structure With this fix, demangling utils would work out-of-the-box.
