A long time ago, when I devised the grammar and structure of the Microsoft C++ name mangling scheme (decorated names), the document describing the object model and the name decoration scheme were made publically available. Perhaps this is still available publically, or perhaps Microsoft might be willing to share an up to date definition of the name-decoration grammar, especially in light of the

I tried, but seemed not to work. For example, when I run a command as below: c++filt _ZNSt4listIiSaIiEEaSERKS1_ The output remains the same as the input symbol. By the way,

Hi, We have a demangler for the Itanium ABI, but looks like we don't have one for the MSVC-style symbols. Is there any good demangler we can import to LLVM? If there's no suitable demangler, I'd like to write one. Currently, we are using `UnDecorateSymbolName` function, but the function is available only on Windows (which is problematic when you are doing a cross-build), and the

You can get the demangled name like so: $ c++filt _ZStlsISt11char_traitsIcEERSt13basic_ostreamIcT_ES5_PKc std::basic_ostream<char,

Hi, everyone! I'm new here trapped by a simple problem for days. When LLVM translates C++ source code to IR, it will add a prefix to the function name. For example: source code: int foo(){ return 1; } IR form: define i32 @_Z3foov() #0 { entry: ret i32 1, !dbg !20 } The getName() method returns _Z3foov, then how can I get foo? I know the debugging information is contained in

Hello all, I'm getting started on a project using LLVM's opt tool to do static analysis, printing call graphs and such. When compiling C programs to IR (and eventually to call graphs), function names remain the same (main, function1, function2 etc.), but when compiling the same program as C++, the function names often have cruft added to them (_Z9function1v, _Z9function2v etc.) which

Hello! We want to implement in-process symbolizer for {Address,Thread}Sanitizer testing tools that would be based on LLVM libraries. I've noticed that llvm-nm (as well as other tools) doesn't demangle C++ names. Is it true, that LLVM doesn't have the code that is capable of that, and if yes, are there any plans to add it? Depending on something like libiberty.a doesn't seem like a

When I use llvm-2.5 to compile gnash which is a GNU flash movie player, some errors appeared as follow: llvm-ld: error: Cannot link in module '../libcore/.libs/libgnashcore.a(movie_root.o)': Linking globals named '_ZNKSt6vectorIN5gnash8geometry7Range2dIfEESaIS3_EE4sizeEv': symbols have different visibilities!

I tree to compile the LLVM ORC JIT examples. But I'm stuck in some problems I can't solve my own. First at all I compile with C++14 enabled with latest stable LLVM and clang, this means 4.0.1. I get the following error. Do I missed some specific compile option? Compilation looks like this here. |CompilingcontribJIT.cpp PWD:/home/ikuehl/projects-llvm/TurboLisp/domainEngineer

After converting a piece of C++ code to C one of the functions that are generated is this: _ZStlsISt11char_traitsIcEERSt13basic_ostreamIcT_ES5_PKc Where is it defined and where can I find the source for it? I need the source to compile it with a C compiler (AMPC) that will convert the C code to Java Bytecode. If the above function is in C++ then I need to convert it to C first. Here's the
