similar to: Clang function naming conventions

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 everyone, I'm working on a library for runtime introspection of C++ programs, for example, getting stack traces, decorating logs with source file information, etc. It currently uses LLVMObject and LLVMDebugInfo. There's a feature I want to add, but it requires that I understand where on the stack local variables are located. For this to work on x86-64, I would need to do whole

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 want to declare a function that matches C ABI. Do I need to transform declarations like void @f(%struct.A %a) into void @f(%struct.A* byval %a) myself or LLVM can do it for me? Is this what "ccc" calling convention means? - Paweł -------------- next part -------------- An HTML attachment was scrubbed... URL:

It is $target dependent. I’m curious what makes you think it is $host dependent.

Thanks Jon. Actually I tried “x86_64-linux”, but it makes the test “Unsupported” from my linux machine, and it was because my test is under clang, not llvm. It seems that clang doesn’t support “x86_64-linux” yet. Thanks again!

I don't see a way to create a ConstantDataVector from Constant or form APFloat though. Did I oversee that? Is the solution to had a new get function in ConstantDataVector to allow that? Any hint on what would be the right fix otherwise?

Eric, Attached are patches for llvm and clang that implement this. I've made 'none' a component that must be added explicitly (i.e. don't turn arm-eabi into arm--none-eabi, but rather turn it into arm--unknown-eabi) to try to reduce surprises. It also keeps the normalization logic a bit simpler than it would otherwise have to be. SPIR triples were one place where I was

Thanks Dan and Jon. I made an incorrect assumption that the "use" iterator was actually giving me the "user" when de-referencing it. Did it always have this behavior in previous LLVM versions? I've seen lots of examples of the "use" iterator being dereferenced and resulting Instruction pointer being treated as the "user"? Thanks, Zack On Tue, Jun 9,

Well, it is going to be "CMake only". Anyone who depends on autotools is going to be stuck on whatever the last revision is that we shipped with it. And I really don't see it being feasible

Does anybody else have an opinion on this issue? I'm planning to submit a patch which would add a new get method for ConstantDataVector taking an ArrayRef<Constant*> and use that in the few places in constant propagation where convertToFloat is used. Let me know if you think there is a more obvious way to do it. Right now the only way to create a ConstantDataVector are those method:

Jon, I need to create a database of basics blocks and their execution time. The only thing I'm concerned is if a block A is more expensive than a block B. Do you think that even with the overhead I would be able to get the A > B information? Like: overhead + time(A) > overhead + time(B) => A > B. If so, I'm not too much concerned about the accuracy. Not sure if I was clear,
