llvm dev - Aug 2014 - [LLVMdev] llvm::Triple support for haswell-enabled x86_64

I'm working on LLDB and we have a bunch of code that is manually
manipulating triples and doing a bunch of nasty stuff to account for the
fact that llvm::Triple doesn't currently have a way to detect x86_64h.

Is this something that llvm::Triple could be modified to support?  Either
as a new ArchType, or a new SubArchType?

Sure, go for it. It’d be a fairly natural fit for a SubArchType.

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?
