[LLVMdev] using -debug-ir to map identify IR mapping

[Muneeb Khan]

Hi,
I am using the -debug-ir pass in LLVM-3.5 opt tool to map binary information back to the IR instead of the source files.
I use the opt tool to  generate a .ll file. But when I run the llc tool on it to generate an assembly (or object) file, it gives me the following warning

warning: ignoring debug info with an invalid version (0) in 

How can I use the debug-ir functionality to achieve a mapping from the binary to the IR?
Thanks!
