- * This helper does the inverse operation of
- * SHUFFLE_32BIT_LOAD_RESULT_TO_64BIT_DATA.
- *
- * We need to do this when we are going to use untyped write messsages that
- * operate with 32-bit components in order to arrange our 64-bit data to be
- * in the expected layout.
- *
- * Notice that callers of this function, unlike in the case of the inverse
- * operation, would typically need to call this with dst and src being
- * different registers, since they would otherwise corrupt the original
- * 64-bit data they are about to write. Because of this the function checks
- * that the src and dst regions involved in the operation do not overlap.
