[Dwarf-Discuss] DW_AT_specification chains

[Marcel Mettes]

Hello,

I was wondering what the semantics are of a series of DW_AT_specifications
that are supposed to form some kind of chain?

For example

    X1 TAG_variable
    X2     DW_AT_name = "x"
   
    Y1 TAG_variable
    Y2     DW_AT_specification = X1
    Y3     DW_AT_external = 1
    Y4     DW_AT_type = ...


    Z1 TAG_variable
    Z2     DW_AT_specification = Y1
    Z3     DW_AT_location = ...

Would this be valid or should the DW_AT_specification at offset Z2
point directly to X1?

Best regards,
Marcel
