public static record JitType.LongJitType(int size) extends Record implements JitType.SimpleJitType<Types.TLong,JitType.LongJitType>
The p-code types for integers of size 5 through 8, i.e., that fit in a JVM long.

  • Field Details

  • Constructor Details

    • LongJitType

      public LongJitType(int size)
      Compact constructor to check the size
      Parameters:
      size - the size in bytes

  • Method Details

    • forSize

      public static JitType.LongJitType forSize(int size)
      Get the type for an integer of the given size 5 through 8
      Parameters:
      size - the size in bytes
      Returns:
      the type
      Throws:
      IllegalArgumentException - for any size not 5 through 8

    • pref

      public int pref()
      Description copied from interface: JitType
      The preference for this type. Smaller is more preferred.
      Specified by:
      pref in interface JitType
      Returns:
      the preference

    • nm

      public String nm()
      Description copied from interface: JitType
      Part of the name of a JVM local variable allocated for this type
      Specified by:
      nm in interface JitType
      Returns:
      the "type" part of a JVM local's name

    • bType

      public Types.TLong bType()
      Description copied from interface: JitType.SimpleJitType
      The JVM type of the variable that can represent a p-code variable of this type
      Specified by:
      bType in interface JitType.SimpleJitType<Types.TLong,JitType.LongJitType>
      Returns:
      the primitive type (not boxed)

    • ext

      public JitType.LongJitType ext()
      Description copied from interface: JitType
      Extend this p-code type to the p-code type that fills its entire host JVM type.

      This is useful, e.g., when multiplying two int3 values using imul that the result might be an int4 and so may need additional conversion.

      Specified by:
      ext in interface JitType
      Specified by:
      ext in interface JitType.SimpleJitType<Types.TLong,JitType.LongJitType>
      Returns:
      the extended type

    • asInt

      public JitType.LongJitType asInt()
      Description copied from interface: JitType.SimpleJitType
      Re-apply the integer behavior to this type

      This may be slightly faster than JitTypeBehavior.INTEGER.resolve(this), because each type can pick its int type directly, and integer types can just return this.

      Specified by:
      asInt in interface JitType.SimpleJitType<Types.TLong,JitType.LongJitType>
      Returns:
      this type as an int

    • legTypesBE

      public List<JitType.LongJitType> legTypesBE()
      Description copied from interface: JitType
      Get the p-code type that describes the part of the variable in each leg

      Each whole leg will have the type JitType.IntJitType.I4, and the partial leg, if applicable, will have its appropriate smaller integer type.

      Specified by:
      legTypesBE in interface JitType
      Specified by:
      legTypesBE in interface JitType.LeggedJitType<Types.TLong,JitType.LongJitType>
      Returns:
      the list of types, each fitting in a JVM int, in big-endian order.

    • legTypesLE

      public List<JitType.LongJitType> legTypesLE()
      Description copied from interface: JitType
      Get the p-code type that describes the part of the variable in each leg

      Each whole leg will have the type JitType.IntJitType.I4, and the partial leg, if applicable, will have its appropriate smaller integer type.

      Specified by:
      legTypesLE in interface JitType
      Returns:
      the list of types, each fitting in a JVM int, in little-endian order.

    • 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 '=='.
      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.

    • size

      public int size()
      Returns the value of the size record component.
      Specified by:
      size in interface JitType
      Returns:
      the value of the size record component
