183

* library function memmove() for most cases.
329
+
* However, where the source and/or destination references
330

* an instruction RAM or ROM or a data RAM or ROM, that
331

* source and/or destination will always be accessed with
332

333
+
* types of devices).

+
*
335
+
* !!!!!!! XTFIXME:
336
+
* !!!!!!! Handling of IRAM/IROM has not yet
337
+
* !!!!!!! been implemented.
338
+
*
339
+
* The (general case) algorithm is as follows:
340
+
* If end of source doesn't overlap destination then use memcpy.
341
+
* Otherwise do memcpy backwards.
342
+
*
343
+
* Register use:
344
+
* a0/ return address
345
+
* a1/ stack pointer
346
+
* a2/ return value
347
+
* a3/ src
