Proper values for LLVMCreateTargetMachine

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,


Hi Timothy,

In this example either Host or NVPTX target machine is created and then used for code generation:

This example in turn was long ago studied from llc.cpp, I think.

So the basic idea is first to select triple, then create target for this triple, then create target machine from target, triple and extra target-specific options.

If you are compiling for native host, default triple would suffice:

Triple triple;

Hope it helps.
