-!
-! 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.
