Record Class JitNopOp

java.lang.Object
java.lang.Record
ghidra.pcode.emu.jit.op.JitNopOp
Record Components:
op - the p-code op
All Implemented Interfaces:
JitOp
public record JitNopOp(PcodeOp op) extends Record implements JitOp
The use-def node for a JitPassage.NopPcodeOp or an inlined PcodeOp.CALLOTHER.

When a callother is inlined, we preserve the original op for bookkeeping, but ensure that no code is emitted for it by wrapping it in this use-def node class.

  • Constructor Details

    • JitNopOp

      public JitNopOp(PcodeOp op)
      Creates an instance of a JitNopOp record class.
      Parameters:

      true if removable

    • link

      public void link()
      Description copied from interface: JitOp

      Specified by:
      link in interface JitOp

    • unlink

      public void unlink()
      Description copied from interface: JitOp
      Remove this op from the JitVal.uses() of each input operand, and (if applicable) unset the JitOutVar.definition() of the output operand.

      unlink in interface JitOp

    • inputs

      public List<JitVal> inputs()
      Description copied from interface: JitOp
      The input operand use-def nodes in some defined order
      Specified by:
      inputs in interface JitOp
      Returns:
      the list of inputs

    • typeFor

      public JitTypeBehavior typeFor(int position)
      Description copied from interface: JitOp
      Get the required type behavior for the input at the given position in JitOp.inputs()
      Specified by:
      typeFor in interface JitOp
      Parameters:
      position - the input position
      Returns:
      the behavior

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()

      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • op

      public PcodeOp op()
      Returns the value of the op record component.
      Specified by:
      op in interface JitOp
      Returns:
      the value of the op record component
