[LLVMdev] llvm get globals definition line number

[Alexandru Ionut Diaconescu]

However, I do have:

    !924 = metadata !{i32 786484, i32 0, null, metadata !"r", metadata
!"r", metadata !"", metadata !841, i32 19, metadata !56, i32 0, i32 1, i32*
@r} ; [ DW_TAG_variable ] [r] [line 19] [def]

with on which `!0` is indirectly dependent and there is `!llvm.dbg.cu =
!{!0}` .
