- * This means we cannot use the byte-swapping load/store instructions

- * For 16-bit, 24-bit, and (on UC series) 32-bit loads, we instead use
- * the LDINS.B instruction, which gcc fails to utilise with the
- * generic code.  GCC also fails to use plain LD.W and ST.W even for
- * AP processors, so we override the generic code.  The 64-bit
