+ generation process) of CTF/BTF types given a typeID.
+
+ Secondly, in the emitted BTF section, BTF Types need to be in the sorted
+ order of their type IDs. The BTF types section is viewed as an array,
+ with type IDs used to index into that array. It is essential that every
+ type be placed at the exact index corresponding to its ID, or else
+ references to that type from other types will no longer be correct.
+
+ - References to void types are converted to reference BTF_VOID_TYPEID. In
+ CTF, a distinct type is used to encode void.
+
+ - Bitfield struct/union members are converted to BTF encoding. CTF uses
+ slices to encode bitfields, but BTF does not have slices and encodes
+ bitfield information directly in the variable-length btf_member
+ descriptions following the struct or union type.
+
+ - Unrepresentable types are removed. We cannot have any invalid BTF types
+ appearing in the output so they must be removed, and type ids of other
+ types and references adjust accordingly. This also involves ensuring that
+ BTF descriptions of struct members referring to unrepresentable types are
+ not emitted, as they would be nonsensical.
+
+ - Adjust inner- and inter-type references-by-ID to account for removed
+ types, and construct the types list. */
