IR.DecompiledExp.vpath * IR.Typ.t option
find the dexp, if any, where the given value is stored also return the type of the value if found
val hpred_is_open_resource :
IR.Tenv.t ->
'a Prop.t ->
Predicates.hpred ->
IR.PredSymb.resource option
Check whether the hpred is a |-> representing a resource in the Racquire state

IR.Procname.t option ->
IR.Exp.t ->
IR.Exp.t ->
IR.Exp.t ->
IR.Procdesc.Node.t ->

in terms of a source expression using the formal parameters of the call
val explain_divide_by_zero :

string option ->
bool * Absint.Localise.error_desc
Produce a description of a leak by looking at the current state. If the current instruction is a variable nullify, blame the variable. If it is an abstraction, blame any variable nullify at the current node. If there is an alloc attribute, print the function call and line number.
