- * Notably, this entire approach is somewhat error prone, and in the event

-! 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 minimum 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.

-/* Imported into Linux kernel by Richard Curnow.  This is used to implement the
-   __copy_user function in the general case, so it has to be a distinct
-   function from intra-kernel memcpy to allow for exception fix-ups in the
-   event that the user pointer is bad somewhere in the copy (e.g. due to
-   running off the end of the vma).
-
-   Note, this algorithm will be slightly wasteful in the case where the source
-   and destination pointers are equally aligned, because the stlo/sthi pairs
-   could then be merged back into single stores.  If there are a lot of cache
-   misses, this is probably offset by the stall lengths on the preloads.

-! 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 minimum 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.

- *    * cost partly independent of range size
