To: gcc-bugs
Rotate patterns that split byte sized rotates into moves do not correctly
consider overlap of operands.
This was noted on a similar but different shift bug
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39635
and detailed here
http://lists.gnu.org/archive/html/avr-gcc-list/2009-03/msg00158.html
Bug raised to reference separate testcase and fix.
