+/// An OpenMP dialect related pass for FIR/HLFIR which performs some
+/// pre-processing of MapInfoOp's after the module has been lowered to
+/// finalize them.
+///
+/// For example, it expands MapInfoOp's containing descriptor related
+/// types (fir::BoxType's) into multiple MapInfoOp's containing the parent
+/// descriptor and pointer member components for individual mapping,
+/// treating the descriptor type as a record type for later lowering in the
+/// OpenMP dialect.
+///
+/// The pass also adds MapInfoOp's that are members of a parent object but are
+/// not directly used in the body of a target region to it's BlockArgument list
+/// to maintain consistency across all MapInfoOp's tied to a region directly or
+/// indirectly via an parent object.
