implementation of the two intrinsics is actually very
similar. In this case, the difference would be that
llvm.stackmap does not reserve space for patching, while
llvm.patchpoint does.</blockquote>

given that stackmap takes an argument indicating the
number of nops to emit as well, but it's not worth
debating this any more. Let's move on. We can revisit
this once I'm actually using the new intrinsics and can
provide real concrete feedback. <span

I want this to be clear when we expose the intrinsics to other
developers. I’ve been making an effort to improve the docs: <a

Please let me know where clarification is needed</blockquote>
I responded in the review. The only big thing that might be worth
discussion here is the "full resume" semantics which are mentioned
at the very end. This seemed to disagree with our previous
discussion. Let me know if you're either a) unclear at what I was
getting at or b) believe the "full resume" semantics were a key part
of the intrinsic. In either case, we should probably hash it out
here. <br>
