As to why that flag is set, I'm at a loss. I have run through GDB with both the sin and putchard examples, to try and see where they are diverging. I'm not totally sure, but I think the divergence might be happen...

For llvm-dwarfdump we need to handle relocations inside the debug info sections in order to successfully dump the dwarf info including strings. Nick sent out a partial patch that did this not too long ago and I've taken it and gone in a bit of a different direction, but kept the same basic architecture. In place of applying the relocations to the data we've read from disk I'm keeping

Having something like this available in tree would definitely be useful. For simplicity, why don't we start with support for the second style? This is the long term useful one and would be a good starting point for getting the code in tree. Can you give a pointer to the patch so that I can assess the rough complexity? If it's simple enough, I'd be happy to help get it reviewed
