Is it possible to write LLVM IR but not using C++? I'm exceedingly terrible at C++. I was thinking, isn't it possible to write the IR using Java? I effectively have emit some sort of binary op codes to be passed into llvm right? The same thing for if I wanted to integrate a GC?

You can write LLVM IR by hand as far as that is concerned ... If you mean generating IR automatically from a program written in some language you need to use a compiler frontend based on LLVM and emit IR instead of going further with the compilation. Most of the frontends for LLVM target C like languages, but with Dragonegg you could use some of the GCC frontends to start from something else. I know that Dragonegg supports Go and not so complex java programs Marcello 2014-10-13 10:35 GMT-07:00 Dave Pitsbawn <dpitsbawn at gmail.com>:> Is it possible to write LLVM IR but not using C++? > > I'm exceedingly terrible at C++. > > I was thinking, isn't it possible to write the IR using Java?

Got it. That's much better than C++! I think you answered my question by pointing to llvmpy about the opcode part.

[http://www.llvmpy.org/]LLVM also has C bindings. I'm not aware of a tutorial specifically for these bindings, but a great reference for things along the line of "how do use LLVM as my language's backend" is the Kaleidoscope tutorial: http://llvm.org/docs/tutorial/ (which has guides for both OCaml and C++).
