I’m using an existing pass called ModuleDegbugInfoPrinter, run it with “-analyze -module-debuginfo” It should print out all the debug information of a module.

For the CompileUnit part, what is exactly a “compile unit” ? A module? a file ? or what ?

In my case, it only prints out one module, which indicates a runtime library source file, and among all the subPrograms it printed out, there is no one coming from user code. So I think either the Compile units are missing or the debug information for user functions are missing. Any clue on why this happened ? (I used -g option when I got the .bc code)
