llvm dev - Jun 2019 - Build libclang.dll exporting C APIs for both Clang and LLVM

Hi,

I would like to use both LLVM and Clang C APIs via the runtime ffi of
a scripting language.

Is it possible to build a libclang.dll that embeds both llvm and clang
and exports the Clang and LLVM C APIs (and no C++ symbols) using
mingw64?

Did anyone tried that before?

Thanks!

Possible? Sure. Is this supported in the current build system? No.

Not that I'm aware of.

To do it you would basically need to grab the LLVM C export list that
llvm/tools/llvm-shlib generates, and add that the the clang exports list that
clang/tools/libclang contains. That would give you LLVM + libClang. If you need
other Clang CAPIs you'd also need to build a mechanism for generating those
export lists.

Totally possible, but not supported.
