/* A jump function for a callsite represents the values passed as actual
parameter or can apply one simple binary operation to it (such jump
functions are called polynomial).
- IPA_JF_KNOWN_TYPE is a special type of an "unknown" function that applies
- only to pointer parameters. It means that even though we cannot prove that
- the passed value is an interprocedural constant, we still know the exact
- type of the containing object which may be valuable for devirtualization.
-
Jump functions are computed in ipa-prop.c by function
update_call_notes_after_inlining. Some information can be lost and jump
functions degraded accordingly when inlining, see
