As I said in the review, it may end up being faster, because of the<br>
amount of crap we'll remove from all tools and LLVM.<br>

I don't know which of them yet, but I'll certainly need CPU/FPU/ARCH<br>
names, register names, feature names and anything to populate a target<br>
description object.<br>
<br>
I moved them all into the include file because I didn't want to have<br>
to choose now and get it wrong. I realise that this might not have<br>
been the best course of action.<br>
<br>
Having said that, we can always go back. So, I'm open to suggestions.<br>
I could start with only a few per arch, and then add as we see fit. My<br>
guess is that only ARMGenRegisterInfo.inc and ARMGenSubtargetInfo.inc<br>
would be a good start, with possibly ARMGenCallingConv.inc and<br>
ARMGenInstrInfo.inc being the next ones to add for Clang's benefit.<br>
<br>
That would mean separating the calls to tablegen() between<br>
CMakeLists.txt and CMakeTblgen.txt, but that's ok.<br><br></blockquote><div><br></div><div>Other than building it, I admit that I'm curious what sort of thing you've got planned for how to vend the information.
