interesting ... just curious, why did they delete "-debug-ir" to begin with
Also, it's extremely interesting that gdb and lldb can be used to debug
LLVM IR. How does your code work (on a high level)? A high level
explanation will help me understand what you've done better.
>From first glance, my idea is slight different because your code interfaces
with gdb and lldb while i'm more interested in making the debugger itself
(sort of an extended interpreter).
