Class OneLevelInliner

java.lang.Object
  harpoon.Analysis.Quads.DeepInliner.OneLevelInliner

public class OneLevelInliner
extends Object

OneLevelInliner contains the code that inlines a single CALL instruction. This class is used by DeepInliner, but can also be used separately, for inlining call paths of length 1.

To perform inlining, use the static method OneLevelInliner.inline.

Method Detail

inline

public static Map<Quad,Quad> inline(CALL cs,
                                    HMethod callee,
                                    CachingCodeFactory ccf)

Parameters:

cs - The call instruction to be inlined.

callee - The callee whose body should replace cs. In case of a virtual call with a single possible callee, this callee is not obvious from the structure of the call (it may require a full-program call graph). Therefore, we require that the callee is passed explicitly.

ccf - The caching code factory that generates the code for callee and for the caller of callee (the method that cs belongs to). We perform the inlining by mutating the cached code for the caller. Must produce QuadNoSSA or QuadRSSx IR (otehr IRs are too complex to generate code for).

Returns:

A map that assigns to each quad from the code of callee (as provided by ccf), the corresponding quad from the copy of callee's body that replaces cs.
