Hello, Does anybody know whether the functionality of generating C code from LLVM IR is still available? As described in the document of getting started with VS, to compile IR to C you can use "llc -march=c hello.bc". But it no longer works.

Found it in 2.6 release note. It is no longer considered as release criteria and no more maintenance on this.

Thanks for Anton's reply. Does anybody have an idea of roughly how much effort is required to make intel asm printer to be usable? If it is within weeks, probably I can give it a try.

The required efforts equal to ones required to write new assembler. "Too weak to be usable" means "it's not possible to represent many important constructs with masm/nasm/fasm". -- With best

...nd line option that is required for generating NASM assembly code. Looked into the document and command line help. But I cannot find anything that helps. I would appreciate it if anyone could provide some hint. BTW: The getting started document with Visual Studio looks very out-of-dated.

That's correct. Use AT&T asm printer and GNU as everywhere. Everything else is too weak to be usable and thus one should consider intel asm printer to be of "listing quality". -- With

Could you give me some examples of such constructs that are not possible to represent with MASM/NASM/FASM but are able to represent with gas?

...cument with regard to relavent problems at that time. Probably I don't need a fully functional production quality assembler for my purpose. If I could find out that the gap between the current llc and what I need is not huge, I would like to enhance the llc Intel ASM printer by myself.
