+!
+! Fast SH memcpy
+!
+! by Toshiyasu Morita (tm@netcom.com)
+! hacked by J"orn Rernnecke (joern.rennecke@superh.com) ("o for o-umlaut)
+! SH5 code Copyright 2002 SuperH Ltd.
+!
+! Entry: ARG0: destination pointer
+!        ARG1: source pointer
+!        ARG2: byte count
+!
+! Exit:  RESULT: destination pointer
+!        any other registers in the range r0-r7: trashed
+!
+! Notes: Usually one wants to do small reads and write a longword, but
+!        unfortunately it is difficult in some cases to concatanate bytes
+!        into a longword on the SH, so this does a longword read and small
+!        writes.
+!
+! This implementation makes two assumptions about how it is called:
+!
+! 1.: If the byte count is nonzero, the address of the last byte to be
+!     copied is unsigned greater than the address of the first byte to
+!     be copied.  This could be easily swapped for a signed comparison,
+!     but the algorithm used needs some comparison.
+!
+! 2.: When there are two or three bytes in the last word of an 11-or-more
+!     bytes memory chunk to b copied, the rest of the word can be read
+!     without side effects.
+!     This could be easily changed by increasing the minumum size of
+!     a fast memcpy and the amount subtracted from r7 before L_2l_loop be 2,
+!     however, this would cost a few extra cyles on average.
+!     For SHmedia, the assumption is that any quadword can be read in its
+!     enirety if at least one byte is included in the copy.
