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

OK. Thank you. What I want to do is: Fix source code in-place, then feed it to compiler normally. I assume I can fix source code in-place using clang::SourceManager, but I cannot find the appropriate API. Now I know that way is infeasible. Thanks again. 2011/5/5 Joshua Warner <joshuawarner32 at gmail.com> > Wen-Han, > > It sounds like there are two problems here: first is

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.

No, the LLVM Mangler class really only does low-level manglings like '_' prefixing, stdcall mangling on Windows, and escaping funny symbols. The Clang mangler, however, does what you want. But, you'll need to feed it a clang AST in order to get a name out. Depending on the parameters of your function, this may be easy or hard. On Thu, May 9, 2013 at 8:38 AM, B B <blackbox.dev.ml

Hi, To use DTrace on some C++ code, I found that Apple''s implementation had another option "-xmangled". Its usage could be found here: http://blog.mozilla.com/dmandelin/2008/02/14/dtrace-c-mysteries-solved/ And it could be found in Apple''s man page: http://developer.apple.com/documentation/Darwin/Reference/ManPages/man1/dtrace.1.html Is it possible to have that

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.

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?

Hi all, in this case: ... int* p = ... int* q = p; ... How can I know that data-flow from p to q, i.e., which LLVM pass of header files could I use?

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

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, I have a strange problem with Samba on RedHat 7.2. In one directory there is many files with similar long file name (10+ digit file name for many pictures). When I dir this directory, I can see many files with different long file name, but with exactly the same short file name. There is about 3-5 files with the same 8.3 DOS file name. I really don't understand how can it happen and what
