[LLVMdev] How to get an LLVM-compiled executable which could be debugged using gdb

I didn't really understand what you are asking.  If you are compiling using
clang, llvm-gcc or dragonegg then add the -g argument to the command line to
get debug info in the final program, exactly like when compiling with gcc.

Ciao, Duncan.
