;; This test exercises the cross-CU production of type information. Due to
;; unfortunate inputs, when the DW_TAG_variable for the global
;; @a_struct_field8typeDataE is produced it will be done in the CU for 2.cpp.
;; However, the type information for the "a_struct" structure type will have
;; already been produced in 3.cpp's CU. Thus, we'll be creating a DIE in one
;; CU from another CU. Check that when we do so, we get the source file
;; identifier correct -- if the FileID came from the wrong CU then we'd end
;; up with a false declaration file.
;;
;; Due to unrelated reasons there are two copies of the "typeData" static member
;; in this LTO-linked IR -- if that ever gets fitxed, it's fine to drop the
;; duplicate DW_TAG_variable, but we want to keep testing the DW_AT_decl_file
;; that's created across a CU boundary.
