-/* Return: the address of the first occurence of chr in str or NULL
-
-   Inputs:
-	in0:	str
-	in1:	chr
-	in2:	byte count
-
-   This implementation assumes little endian mode.  For big endian mode,
-   the instruction czx1.r should be replaced by czx1.l.
-
-   The algorithm is fairly straightforward: search byte by byte until we
-   we get to a word aligned address, then search word by word as much as
-   possible; the remaining few bytes are searched one at a time.
-
-   The word by word search is performed by xor-ing the word with a word
-   containing chr in every byte.  If there is a hit, the result will
-   contain a zero byte in the corresponding position.  The presence and
-   position of that zero byte is detected with a czx instruction.
-
-   All the loops in this function could have had the internal branch removed
-   if br.ctop and br.cloop could be predicated :-(.  */
