similar to: [LLVMdev] Importing existing function declarations into LLVM C++ API

Hi, I'm trying to find a solution to the following problem: I need to generate a mangled name for given C++ function. Could I use llvm Mangler class for it?

Hello, I'm trying to link a large in-house C++ library into R. So far, I've managed to to most of what I want, but I have one remaining question and a suggestion. The suggestion first: I've found it useful to put #ifdef __cplusplus extern "C" { #endif and #ifdef __cplusplus } #endif around the function prototypes in Rinternals.h (in

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

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

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

By the way, does anyone know of a project which *does* call into Clang's mangling framework from outside? I'd be interested to know purely out of curiosity. Cheers. Tim.

If you want to get the original name by a library function, as Jonathan mentioned, you can call __cxa_demangle in cxxabi.h. However, this API is only available in gcc. If you want something more portable, try glog or libibert, notice libibert is GPL licensed.

How would LLVM provide support for mangling? And what tools actually need it? I also wonder if we need more from a demangler than just a string. I know linker

I have encountered a need for manually generating the mangled name of an arbitrary C++ function. The only way I currently know how to do this is to generate a dummy C++ source file, compile it, and look at the output. This approach is so ugly that I would like for it never to see the light of day. The c++filt tool generates demangled C++ names given the mangled ones, which is the opposite

Hi Xinmin, I have updated the clang patch using the standard name mangling you suggested - I was not fully aware of the C++ mangling convention “_ZVG”. I am using “D” for 64-bit NEON and “Q” for 128-bit NEON, which makes NEON vector symbols look as follows: _ZVGQN2v__Z1fd _ZVGDN2v__Z1ff _ZVGQN4v__Z1ff Here “Q” means -> NEON 128-bit, “D” means -> NEON 64-bit Please notice that although

Howdy, I'm working with some external code written in C++, which I would like to call via dyn.load() and .C() from R. The function prototype looks like: gaRemin(int *, float *, float *, int *, float *, float *, float *, float *, float *) but to call this function from R using .C() I have had to use the mangled version of this

The DynamicLibrarySearchGenerator is using the getAddressOfSymbol method, which (under the hood) is basically issuing an appropriate dlsym lookup, and that does not find

Hi Francesco, a bit more information. GCC veclib is implemented based on GCC VectorABI for declare simd as well. For name mangling, we have to follow certain rules of C/C++ (e.g. prefix needs to _ZVG ....). David Majnemer who is the owner and stakeholder for approval for Clang and LLVM. Also, we need to pay attention to GCC compatibility. I would suggest you look into how GCC VectorABI can
