Hi Nick, Bigcheese, When lld is used to link C++ code, it would be required to demangle symbol names by default/user driven option. The Gnu linker has the following options :- --demangle=[style] --no-demangle I found that clang/llvm-symbolizer use __cxx_demangle function. I would think that lld also need to call the same function, and I think the way we want to demangle is to have the function in LinkingContext as various flavors may choose to use different API's to demangle symbol names. The API's that would be in LinkingContext would be :-...

...r? Or use whatever one is natively available, and fall back to not demangling if the native demangler cannot demangle the given symbol name (e.g. an MSVS symbol on when running on linux). a) The function would be non-virtual. b) I am not planning to write a demangler. I was planning on using abi::__cxx_demangle if there was one available and the first character in the symbol was a _. If MSVC was defined, we would use the Undecorate API.
