[lldb-dev] JIT debugging and Windows

[Tim Holy]

Hi Andrew,

I've been lurking on this list for months, hoping to see a message like this 
one. It really is Christmas :)

Over at the Julia project (http://julialang.org/), we're in need of a good 
debugger. Is your project in a public repository? If so, would you be willing 
to point to a branch or series of commits that shows how far along you are? 

I agree it would be great to see LLDB support this use case.

Best,
--Tim
