--- Comment #4 from Sanjay Patel <spatel+llvm at rotateright.com> ---
As of r233582, this looks fixed. The code near the end that used to be wrong is
now correct:

    movb    $-1, %cl
    movb    $1, %ch
    movb    %cl, %al
LBB0_3:                                 ## %fn1.exit
    movl    L_b$non_lazy_ptr, %edx
    movb    %cl, 12(%edx)
    movb    %ch, 12(%edx)
