;; The test checks, that Fortran dynamic arrays are being correctly represented
;; by SPIR-V debug information
;; Unlike 'static' arrays dynamic can have following parameters of
;; DICompositeType metadata with DW_TAG_array_type tag:
;; Data Location, Associated, Allocated and Rank which can be represented
;; by either DIExpression or DIVariable (both local and global).
;; This test if for expression representation.
;; FortranDynamicArrayVar.ll is for variable representation.
