Hello, I was looking at sys::getDefaultTargetTriple() (file: lib/Support/Unix/Host.inc ) and there is something unclear to me. std::string sys::getDefaultTargetTriple() { StringRef TargetTripleString(LLVM_DEFAULT_TARGET_TRIPLE); std::pair<StringRef, StringRef> ArchSplit = TargetTripleString.split('-'); // Normalize the ar...

Hello everyone, First of all, this is my first posting here, so feel free to tell me if I'm asking the wrong questions in the wrong place. I've discovered that the target triple normalization which used to be done at all times on sys::getDefaultTargetTriple() has been removed, due to the fact that most users of this function explicitly call Triple::normalize() on its result. This has however broken our compiler, which is built upon the LLVM C API, which relied on the default Windows target triple (x86_64-pc-win32 in our case) being normalized to x86_6...

What I don't know is how to get this information into the llvm::Module so that it gets output with an llvm::raw_os_ostream in a way that clang understands. If I could use it with llvm-as without it having to make assumptions, to build shared libraries and programs, that would be great t...

Sounds good, I'll give it a try sooner or later. I've never messed with triples, so is there anything I need to be aware of so I don't break any code on other platforms? In particular, I want llvm::sys::getDefaultTargetTriple() to return me this new haswell-aware triple, so what do I need to do to ensure that I don't break anyone else who is running one of these systems and previously had a different default triple?

I can't seem to get LLVMCreateTargetMachine to work on my box (MBP i7 OS X 10.8). What should the values of triple, cpu and features be? I'm just looking for a way to get this up and going for now, I don't need specific optimizations. No matter what I send the function, I always get nil back. I'm giving it LLVMGetFirstTarget as the target value. Thanks for the help, Timothy
