I suggest you take a look in include/llvm/Support/Host.h

Ciao, Duncan.

I know about getDefaultTargetTriple().

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 too.

Maybe this is related to why llvm::InitializeNativeTarget() fails.
All of this is in my v3c-storyboard project, sb/tests/hello-world3-test.cpp.

I even tried outputting the target triple information myself to the 
header of the .ll file. No luck.
