; Check that the "inlinedAt" attribute of a DILocation references another
; DILocation that is marked as distinct.  Note that the checks for distinct
; DILocations do not include the column number as SPIR-V does not allow for
; representing this info (except for NonSemantic.Shader.DebugInfo.200). For
; this specification we check that the column number is preserved during
; translation.
