Sungkeun Cho 020cd199b5 [cost] Use type of Provider.get Summary: This diff uses a type parameter of `Provider.get` to decide whether assigning expensive cost to the function call or not. For example, if the type is small one like `Provider<Integer>`, it be evaluated to have a unit cost, otherwise a linear cost. To get the return type of `Provider.get`, I added a simple analyzer that collects "casted" types backwards. In Sil, while the function call statement loses the return type, e.g, ``` n$5=_fun_Object Provider.get()(n$3:javax.inject.Provider); ``` the `n$5`'s value is usually casted to a specific type at some point later. ``` &$irvar0:java.lang.Object=n$5 n$8=&$irvar0:java.lang.Object* n$9=_fun___cast(n$8:java.lang.Object*,sizeof(t=java.lang.Integer;sub_t=( sub )(cast)):void) ``` So, the analyzer starts from the cast statements backward, collecting the types to cast for each variables.
