similar to: [LLVMdev] llvm-c headers: How to call external function?

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 am going to post my first chapter, just to see if it is acceptable. Any feedback is good feedback for me.

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.

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

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

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.

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

Hi, Is it possible to create a .dll / .so / .dylib by only using the LLVM-C headers ? If so, I cannot find it. Filip

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:

Dear R-devel: The following code seems to allow one function to permanently modify a calling function. I did not expect this would be allowed (short of more creative gymnastics) and wonder if it is really intended. (I can see other ways to accomplish the intended task of this code [e.g. via match.call instead of substitute below] that do not trigger the problem, but I don't think that is

I really need your help guys, I am using the AGI mode in meetme application, and I want that AGI should wait for an input from the client/user i.e. a digit and then proceed, but I have used that AGI function agi->wait_for_digit(), but no use....my agi just passes, or ignores this function, where AGI should stop here and wait for the input.... .....my extension in my

Hi Filip, It's best to email llvmdev, not me directly. A place to start helping is to start working on a new tutorial! :) -Chris On Jul 5, 2010, at 2:29 PM, F van der Meeren wrote: > Will there be any change in this situation? > And if not, how can I help? > > Filip > > On 04 Jul 2010, at 19:34, Chris Lattner wrote: > >> >> On Jul 4, 2010, at 12:40 AM,

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

Hi all, assume the following problem: a function call takes a function object and a data variable and calls this function with this data on a remote host. It uses serialization to pass both the function and the data via a socket connection to a remote host. The problem is that depending on the way we call the same construct, the function may be serialized to include the data, which was not

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 R-Helpers: I?m trying to fit the same linear model to a bunch of variables in a data frame, so I was trying to adapt the codes John Fox, Spencer Graves and Peter Dalgaard proposed and discused yesterday on this e-mail list: for (y in df[, 3:5]) { mod = lm(y ~ Trt*Dose, data = x, contrasts = list(Trt = contr.sum, Dose = contr.sum)) Anova(mod, type = "III") } ## by John Fox or for

I initially sent this to the biocore mailing list - but it was suggested that r-devel would also find it interesting. Many of us use a macro like #define CALL_DEF(fname, nargs) { #fname, (DL_FUNC)&fname, nargs} for use in function registration for use with .Call. For example, using the example from R Extension manual, if we want to register a C function myCall with three arguments, we

Quick question regarding multicore versions of mapply. Package 'multicore' provides a parallelized version of 'lapply', called 'mclapply'. I haven't found any parallelized versions of 'mapply', however (although one can use the lower level function 'parallel', it becomes harder to control the number of spawned processes etc). Is anyone aware of a
