ExceutionEngine -> ExecutionEngine

First mention in main body text

I mention that you need LLVM installed, and that's all you need beyond a standard OS X developer tools install. The command for building the code is at the top of the full source listing here:

It's odd that you never explicitly mention the tool chain or language or other requirements for actually building this code. It looks like C++, and I know that LLVM or parts of it are in C++... Are the tutorials you mention pre-requisites for understanding this article? What other prerequisites are there?

I haven't done a whole lot with GC, but enough to be familiar. I don't know if I could do your suggestion but I'll put it on the list and think about it. In the meantime, check out "info gc-roots" and "info gc-references" in gdb if you don't already know about them.

Another great topic would be how to go about tracking down "over-rootedness" issues when running in a garbage collected environment. It doesn't seem like the current tools help very much here. Are you doing anything with GC Mike?

Thanks for the suggestion, sounds like a good one. I've added it to the pool.

I'd love to see a tutorial on Core Audio. If you want a more specific request: capturing, and maybe converting close to real time, an audio input?

Yep, running the optimizations is trivial. Next week's example will have them integrated, but that page tells you everything you need to know.

It doesn't seem much complicated:

You just need to know what optimization passes to use...

It would be great to run the LLVM standards optimizations on the intermediate representation before generating native code.
Do you know how to do that?

Really interesting stuff! Looking forward to next week's installment...
