llvm dev - Apr 2013 - [LLVMdev] extracting variables' values at interrupt

Dear all
I have a question and I really appreciate any help.
I'm trying to extract variable values at interrupt of some program. And I
want to do that from JIT.
The situation is that the JIT will interrupt at certain point of executing some
code and tries to get the variables' values.
Any help about that?

This is effectively exactly what a debugger does when introspecting the state of
a running program. Your JIT'ed code will need to use the program's debug
information to get what it wants.

Thanks a million for replying.
I've tried to search about debugger in general and debug in LLVM, but I
couldn't find the answer. Could you please suggest where to look for
debugging info in LLVM? I\m kind of new to LLVM system.
Besides, I want to get these values in the JIT execution engine itself not in
the jitted code.
Thanks again.
