Class SSAInvokeDynamicInstruction


public class SSAInvokeDynamicInstruction extends SSAInvokeInstruction
Used for representing the JVML invokedynamic instruction. When generated by the Java compiler for compilation of Java lambdas / method references, the instruction components are:

The behavior of WALA for other uses of invokedynamic is currently unspecified (though it aims to not crash for any valid use).

      public SSAInstruction copyForSSA(SSAInstructionFactory insts, int[] defs, int[] uses)
      Description copied from class: SSAInstruction
      This method is meant to be used during SSA conversion for an IR that is not in SSA form. It creates a new SSAInstruction of the same type as the receiver, with a combination of the receiver's uses and defs and those from the method parameters.

      In particular, if the 'defs' parameter is null, then the new instruction has the same defs as the receiver. If 'defs' is not null, it must be an array with a size equal to the number of defs that the receiver instruction has. In this case, the new instruction has defs taken from the array. The uses of the new instruction work in the same way with the 'uses' parameter.

      Note that this only applies to CAst-based IR translation, since Java bytecode-based IR generation uses a different SSA construction mechanism.

    • toString

      public String toString(SymbolTable symbolTable)
      Mark the instruction as an invokedynamic. The String will also contain the invocation type of the boostrap method

      Parameters:
      symbolTable - the symbol table
      Returns:
      result of SSAAbstractInvokeInstruction.toString(SymbolTable) with "[invokedynamic] " pre-pended
