Record Class JitCatenateOp

java.lang.Object
java.lang.Record
ghidra.pcode.emu.jit.op.JitCatenateOp
Record Components:
out - the use-def variable node for the output
parts - the inputs to be concatenated
All Implemented Interfaces:
JitDefOp, JitOp, JitSyntheticOp
public record JitCatenateOp(JitOutVar out, List<JitVal> parts) extends Record implements JitDefOp, JitSyntheticOp
The synthetic use-def node for concatenation.

These are synthesized when memory/register access patterns cause multiple use-def variable nodes to be "read" at the same time. E.g., consider AL and AH to be written and then AX read.

      public JitCatenateOp(JitOutVar out, List<JitVal> parts)
      Compact constructor for validation
      Parameters:
      out - the use-def variable node for the output
      parts - the inputs to be concatenated

  • Method Details

    • link

      public void link()
      Description copied from interface: JitOp
      Add this op to the JitVal.uses() of each input operand, and (if applicable) set the JitOutVar.definition() of the output operand to this op.
      Specified by:
      link in interface JitDefOp
      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.
      Specified by:
      unlink in interface JitDefOp
      Specified by:
      unlink in interface JitOp

    • iterParts

      public Iterable<JitVal> iterParts(boolean bigEndian)
      Iterate over the parts from most to least significant
      Parameters:
      bigEndian - the byte order off the machine
      Returns:
      an iterable over the parts

    • 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

    • partType

      public JitTypeBehavior partType()
      We'd like every part to be an int.
      Returns:
      JitTypeBehavior.INTEGER

    • type

      public JitTypeBehavior type()
      Description copied from interface: JitDefOp
      The required type behavior for the output
      Specified by:
      type in interface JitDefOp
      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()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      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.

    • out

      public JitOutVar out()
      Returns the value of the out record component.
      Specified by:
      out in interface JitDefOp
      Returns:
      the value of the out record component

    • parts

      public List<JitVal> parts()
      Returns the value of the parts record component.
      Returns:
      the value of the parts record component
