...y "engine", though, it will automatically choose between these two options for you. This seems like a useful thing to have. For a list of all possible components, run: llvm-config --components You should be able to pick any LLVM library by name.[1] Cheers, Eric [1] Except "LLVMBackend.o", which clashes with the virtual "backend" component, and can only be pulled in by another library. Maybe I should rename the virtual "backend" component. :-(

Hi, I am new to LLVM and I find TableGen language really cryptic. The reference manual to the language is not helpful either. I can look at the existing .td file and reverse engineer but I am looking for a detailed manual. Specifically, I have below questions: 1. What is a basic syntax for writing a dag? From the lang ref manual I can see that its something like operator followed by ArgList which
