-Preserving Debug Information Intrinsics
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-These intrinsics are used to carry certain debuginfo together with
-IR-level operations. For example, it may be desirable to
-know the structure/union name and the original user-level field
-indices. Such information got lost in IR GetElementPtr instruction
-since the IR types are different from debugInfo types and unions
-are converted to structs in IR.
