// This file implements a function which calls the Generic Delta pass in order
// to reduce uninteresting DbgVariableRecords from defined functions.
//
// DbgVariableRecords store variable-location debug-info and are attached to
// instructions. This information used to be represented by intrinsics such as
// dbg.value, and would naturally get reduced by llvm-reduce like any other
// instruction. As DbgVariableRecords get stored elsewhere, they need to be
// enumerated and eliminated like any other data structure in LLVM.
