public static record JitPassage.ErrBranch(PcodeOp from, String message) extends Record implements JitPassage.Branch
A "branch" representing an error

When execution encounters this branch, the run method throws an exception. This branch is used to encode error conditions that may not actually be encountered at run time. Some cases are:

The decoder and translator may encounter such an error, but unless execution actually reaches the error, the emulator need not crash. Thus, we note the error and generate code that will actually throw it in the translation, only if it's actually encountered.

Note that the OpGen for the specific p-code op generating the error will decide what exception type to throw.

      public ErrBranch(PcodeOp from, String message)
      Creates an instance of a ErrBranch record class.
      Parameters:
      from - the value for the from record component
      message - the value for the message record component

  • Method Details

    • 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.

    • from

      public PcodeOp from()
      Returns the value of the from record component.
      Specified by:
      from in interface JitPassage.Branch
      Returns:
      the value of the from record component

    • message

      public String message()
      Returns the value of the message record component.
      Returns:
      the value of the message record component
