...eturns input string) if demangling is not available, the string is not a mangled symbol, or demangling was turned off (--no-demangle). Then, you just wrap a demangle() call around every use. Are you mentioning that one demangle function in LinkingContext ? One demangle method wouldnt work as the ItaniumABI uses one method to demangle, ARMCXXABI uses a different method, and MSVC uses a different one. I am not sure about Mach-O here ? > The __cxa_demangle function has an odd interface that requires a malloc allocated block. Having demangle() return a std::string means yet another allocation.

...and see how it helps. Let's assume the below is true and it won't work on OSX as described (i'm certainly in no place to disagree). Some data points: 1. LLDB works just fine on Darwin (it appears to do the same thing we did in gdb, staring at source/Plugins/LanguageRuntime/CPlusPlus/ItaniumABI/ItaniumABILanguageRuntime.cpp) 2. GDB does not work on Darwin at all for any real debugging right now (You can't debug llvm with it, for example). There are barely working versions here and there. The startup time to debug an "opt" binary from llvm is well over 2 minutes alone to g...

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
