; Checks that DW_AT_decl_file attribute is correctly set for
|

; template function declaration. When using full LTO we likely

|
; end up having multiple CUs in a single DWARF file, and it is
|
|
; possible that we add template function declaration DIE from
|
|
; CU#1 to structure type DIE from CU#2. In such case we should
|
|
; add source line attributes on behalf of CU#2, not CU#1
