; Test loading metadata which was not aware of versioned language names
; nor of the DW_AT_LLVM_language_dialect attribute.
;
; The CU metadata record in this fixture predates both the
; sourceLanguageVersion field (Record index 22) and the dialect field
; (Record index 23). The MetadataLoader must default the dialect to 0
; ("no dialect specified") when the record is shorter than 24 elements,
; and the AsmWriter must omit the dialect attribute since it defaults to
; zero (printDwarfEnum skips zero values).
