llvm dev - Jun 2009 - [LLVMdev] LLVM Compiler Infrastructure and GDB debugger

Hi Artem,

GDB only works with native applications.  If you compile your code to  
a native executable with -g, then debug info should work for you.   
However, if you've built your own backend, then you may need to add  
the debug info hooks etc.  If you have further questions, please email  
the llvmdev mailing list instead of me directly, thanks!

-Chris
