Enum Class FloatEqualOpGen

java.lang.Object
java.lang.Enum<FloatEqualOpGen>
ghidra.pcode.emu.jit.gen.op.FloatEqualOpGen
All Implemented Interfaces:
BinOpGen<JitFloatEqualOp>, CompareFloatOpGen<JitFloatEqualOp>, OpGen<JitFloatEqualOp>, Serializable, Comparable<FloatEqualOpGen>, Constable, org.objectweb.asm.Opcodes
public enum FloatEqualOpGen extends Enum<FloatEqualOpGen> implements CompareFloatOpGen<JitFloatEqualOp>
The generator for a float_equal.

This uses the float comparison operator generator and simply emits Opcodes.FCMPL or Opcodes.DCMPL depending on the type and then Opcodes.IFEQ.

    • values

      public static FloatEqualOpGen[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static FloatEqualOpGen valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
