similar to: [LLVMdev] LLVM-C headers: create native library

Aside from using the C API, you cannot create dynamic libraries with LLVM. For that you need a linker. LLVM generates assembly files (.s) and very soon it will generate object files natively (.o). The clang driver generally uses an installed gcc to do the assemble and link steps at the moment. Reid On Tue, Jul 6, 2010 at 7:51 AM, F van der Meeren <llvm-dev at code2develop.com> wrote:

I think it'd be nice to have a ToC describing what you plan to cover in the "hello world" tutorial. I'll take a look at the tutorial in the week end and send feed back.

As I have stated before, I am creating a LLVM-C tutorial. Now I expect it to be in a final draft form within 2~3 weeks, but how do I have to deliver it to the community? - File format ? - Style ? - ... Thank you, Filip

I am still having some trouble finding my way in the C++ files. Could you give me a clearer direction?

I see. I assumed it runs binutils directly.

Most of the documents (html) are generated using rst2html. So I think a patch to the rst file in llvm/tools/llvmc/doc should be fine.

If you have llvm IR then you can use 'llc' to generate c code. Try $ llc <input_llvm_ir> -march=c -o /tmp/output.c This C backend is implemented in llvm/lib/Target/CBackend - Devang

Hi, I am trying to get started with the llvm-c headers. Is there any place where I can get/retrieve documentation about it? Such as a basic tutorial, memory managment... Thank you, Filip

I thought it uses binutils. It does. But clang uses the gcc driver to invoke the binutils tools anyway. Presumably it's easier that way. Reid

Hello, I have a question concerning llvm-c. I have set up a function that needs to invoke an external method, in a other library. It has the following signature: void* NSFullUserName(void); The void* can be replaced with a i8*, that far I was able to get, but when my call is invoked, the engine gives me the following message: LLVM ERROR: Tried to execute an unknown external function: i8* ()*

I don't see why not. C is a worthy language, one that I think we should fully support. And by just providing some minor features really limits its usefulness. Right now, at this very instance it isn't usable. Except as a stepping stone to the bigger framework. But thats just my 2 cents. - Filip On 16 Sep 2010, at 19:51, Eric Christopher wrote: > > On Sep 16, 2010, at 5:35 AM, F

That won't work when you are trying to limit yourself to C and only C. Is there an LLVM-C alternative?

Hello, I am trying to emit C code from the module I just created. And this from LLVM-C. If someone could give me a pointer on how to do this in llvm (with C++) I might be able to figure it out how to do it in LLVM-C or write my own LLVM-C wrapper for it. Thank you, Filip

That was all I needed to hear :-) Because I am already at "chapter 3", which is regular expressions in C, but then made so that each regex becomes a real and true function. And doubt suddenly struck. What if my style isn't exactly what the LLVM community wants... On 01 Sep 2010, at 15:09, nessim wrote: > hey Filip, > > I'm afraid i can't give you technical

Ok I see. Of course, at runtime, it's enough for dynamic linking or for deoptimization. However, wmkit acts both as a jit and as an aot. For the aot, it means that I can not use patchpoint and that I should have two different compilation strategy. It's not so difficult, but in this case, I can not use patchpoints to generate gc's stackmap for the aot (basically, I think that I could
