[LLVMdev] making emitInlineAsm protected

It may be moot because Reed is currently rewriting the patch to avoid using EmitInlineAsm and EmitRawText but I wanted to question something here.

I'm thinking that hasRawTextSupport() shouldn't be the condition used inside EmitInlineAsm. I think it would be more correct to have a useRawTextSupport() predicate that can return hasRawTextSupport() for (sub)targets that haven't implemented their MC layer, and false for those that have. What do you think?
