Detailed Description

This file defines a pass that propagates FortranVariableFlagsAttr attributes through HLFIR. For example, it can set contiguous attribute on hlfir.designate that produces a contiguous slice of a contiguous Fortran array. This pass can be applied multiple times to expose more Fortran attributes, e.g. after inlining and constant propagation.
