I am doing a strange project, I don't have the ast to join the line number information inside, then I am xxir (my own definition of intermediate code format) turn llvmir use
```c
LLVMInstructionSetDebugLoc (r, loc);
```
Added line number information, but now there is a problem, llvmir and dwarfdump line number information is different, dwarfdump line number information has a part of 0 line
```
attributes #0 = { "frame-pointer"="all" "frame-reserved-slots"="16" }
attributes #1 = { nocallback nofree nosync nounwind readnone willreturn }
attributes #2 = { nounwind readonly }
attributes #3 = { cold }

```
What could be the reason for this?
