[LLVMdev] a problem of jit debug

[Reid Kleckner]

Yes, to be clear, the support in LLVM for debugging JITed code only
works on Linux, so far as I know.  I made an attempt to make it work
on Darwin, but it didn't get anywhere.

You should still be able to debug your application on Windows if frame
pointers are preserved, you just won't be able to examine the frame
itself.
