+ * Removed 10/2016. ARGI_FIXED_TARGET was used for these operators:
+ * from_BCD
+ * to_BCD
+ * to_decimal_string
+ * to_hex_string
+ * to_integer
+ * to_buffer
+ * The purpose of this type was to disable "implicit result conversion",
+ * but this was incorrect per the ACPI spec and other ACPI implementations.
+ * These operators now have the target operand defined as a normal
+ * ARGI_TARGETREF.
