--- Comment #9 from Tony Poppleton <tony.poppleton at gmail dot com> 2013-04-10 02:01:27 UTC ---
GCC 4.8.0 with -O2 produces something similar to the original, so the
regression noted in comment #7 and comment #8 is now resolved.
movzbl (%rdi), %eax
shrq $4, %rax
movq table(,%rax,8), %rax
ret
However the original bug from comment #1 is still present.
