Hi,

I've written some Deimos interface for LLVM.
https://github.com/jkm/deimos-llvm/commits/master

I'd like to get some feedback on those.
Firstly to finish these and secondly to finish some guidelines that I'd
like to propose to be published on dlang.org.

Very interesting. I'd be interested in making some D Native 
feeling bindings, because the LLVM C bindings are A, 
inconsistent, and B, complete shit. So this is interesting.

Building a better wrapper on top of these would be nice. Can you give examples for A and B? Jens

The verbs used change from function to function. I can't remember any off the top of my head, but I run into bunch when using it for SDC. As to B, they're incomplete, undocumented, and awkward to use. No reflection on your fine work, of course. :)

I see. Maybe they will improve.

Yeah. I just translated those header files. I haven't written them. Jens

I tried with my port of the Kaleidoscope, apart from some comestic changes, it worked like a charm ! (Using LLVM 3.0) Here's the diff: https://github.com/mlarouche/llvm-d-tutorial/commit/8e3b53a1040db672c16fd0685bd0e6fd7d075b48#main.d

Thanks. To be honest I took your main.d to verify that it works. But I'm unsure what kind of examples to add to make sure it works. Just want something simple but complete. Jens

Are the bindings for 3.0 or 3.1? I'm asking because at least some enum members have changed (don't exactly remember which).

Ok great, then I can throw away my bindings :) (unfortunately I couldn't publish them because of my former employee...). Btw. regarding Barnard's comment about LLVM-C, I partially agree. Several additions/modifications were necessary in my case to be able to make the compiler fully work. I wonder if it's feasable to compile LLVM using DMC and then use extern(C++) to make an object oriented interface at some point, possibly using SWIG or something. But well.. apart from some missing features, I think the C interface is actually OK to work with, once you get over the missing documentation, so maybe it's really not worth the time.

I thought it doesn't yet support C++? But anyways, next time I have to make bindings for a C library I'll definitely try dstep.

No, it doesn't support C++. I was thinking about generating bindings for the C API. -- /Jacob Carlborg

The fact that the LLVM C++ API uses templates quite heavily might turn out to be a problem in that regard. I didn't have a look at how feasible it would be to just »pre-instantiate« all the needed combinations, though. David
