  • Constructor Details

    • Entrypoint

      protected Entrypoint(IMethod method)
      Parameters:
      method - the method to be called for this entrypoint

  • Method Details

    • makeSite

      public CallSiteReference makeSite(int programCounter)
      Create a call site reference representing a call to this entrypoint
      Parameters:
      programCounter - the bytecode index of the synthesize call
      Returns:
      the call site reference, or null if failed to find entrypoint

    • makeArgument

      protected int makeArgument(AbstractRootMethod m, int i)
      Add allocation statements to the fake root method for each possible value of parameter i. If necessary, add a phi to combine the values.
      Returns:
      value number holding the parameter to the call; -1 if there was some error

    • equals

      public boolean equals(Object obj)
      Overrides:
      equals in class Object

    • addCall

      public SSAAbstractInvokeInstruction addCall(AbstractRootMethod m)
      Add a call to this entrypoint from the fake root method
      Parameters:
      m - the Fake Root Method
      Returns:
      the call instruction added, or null if the operation fails

    • getMethod

      public IMethod getMethod()
      Returns:
      the method this call invokes

    • getParameterTypes

      public abstract TypeReference[] getParameterTypes(int i)
      Returns:
      types to allocate for parameter i; for non-static methods, parameter 0 is "this"

    • getNumberOfParameters

      public abstract int getNumberOfParameters()
      Returns:
      number of parameters to this call, including "this" for non-statics
