Ah, I was afraid of that, because I do care very much about
optimization -- it's the main reason I'm planning on using llvm for my
compiler backend in the first place.

Any guess at where to start investigating why LLVMInstCombine.lib
might be missing? If there had been an error during the attempt to
compile it, would the build process have stopped there, or just
skipped it and kept going new?

That certainly sounds plausible. How do I build llvm in release mode?
The makefile generated by cmake doesn't include 'debug' and 'release'
targets.

That seems plausible. If it's a bug in Kaleidoscope itself rather than
the libraries, it's not very important.
