val is_only_pt_by_fld_or_param_nonnull : InferIR.Procdesc.t ‑> InferIR.Tenv.t ‑> Prop.normal Prop.t ‑> InferIR.Exp.t ‑> bool

val check_dereference_error : InferIR.Tenv.t ‑> InferIR.Procdesc.t ‑> Prop.normal Prop.t ‑> InferIR.Exp.t ‑> InferBase.Location.t ‑> unit

Check for dereference errors: dereferencing 0, a freed value, or an undefined value

val check_call_to_objc_block_error : InferIR.Tenv.t ‑> InferIR.Procdesc.t ‑> Prop.normal Prop.t ‑> InferIR.Exp.t ‑> InferBase.Location.t ‑> unit

Check that an expression representing an objc block can be null and raise a B1 null exception. It's used to check that we don't call possibly null blocks

val rearrange : ?⁠report_deref_errors:bool ‑> InferIR.Procdesc.t ‑> InferIR.Tenv.t ‑> InferIR.Exp.t ‑> InferIR.Typ.t ‑> Prop.normal Prop.t ‑> InferBase.Location.t ‑> InferIR.Sil.offset list Prop.prop_iter list

rearrange lexp prop rearranges prop into the form prop' * lexp|->strexp:typ. It returns an iterator with lexp |-> strexp: typ as current predicate and the path (an offsetlist) which leads to lexp as the iterator state.
