I know there's been developments in C++/D interop.  I'm wondering what parts are missing to be able to use the LLVM IR Codegeneration libraries in a D application?  I figured I'd ask the LDC guys since you have experience with both LLVM and D. Thanks.

You mean llvm bindings? https://github.com/deadalnix/SDC/tree/master/libd-llvm/import/llvm/c

Hi Jonathan!

There are several D bindings for LLVM which you can use.
The drawback is that they all use the C interface which is sometimes a bit limited. I am not aware that there is a binding for the C++ interface.

So is SDC just a rewrite of LDC in D?

No, SDC is a D compiler written from scratch in D, using LLVM as backend library.

As LLVM is written in C/C++ bindings are required to use it with D. The SDC binding is one of several existing D bindings for LLVM.

Kai, Just curious.  When LDC moves to DDMD, is the plan to continue to use the LLVM C++ interface, perhaps making the C++ glue layer simple enough that D can handle properly, or will there be a switch to the LLVM C interface?

Hi Dan!

I think that the C interface of LLVM does not expose all the stuff LDC is using. We will end with having a C++ glue layer. This could also have a good side effect: we can try to encapsulate the API differences in the glue layer.
