When -O2 is enabled result is 0xFF (255) which is incorrect. The code generated
for the following shift operation:
13: return (left right);
+00AB: C004RJMP PC+0x0005

I already generated a simple testcase (although different)in
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39635. The comments from Andy in
the linked report might be worth reproducing here

Confirmed with gcc 4.4.0. Using switch -O0 with avr-gcc 4.4.0 (-mmcu=atmega128)
gave the result 0 while -O1 gave 0xFF

Adding additional version numbers in the known-to-fail field from comment in
duplicate bug #39635. Still waiting to hear if bug is present in 4.4.

Please try using gcc 4.4 (HEAD). Anatoly Sokolov (AVR port maintainer) has
indicated to me that he does not see this bug when using HEAD/4.4.
