With today's 4.1.x snapshot and on x86_64, I get this at -O2:
----------------
.L4:
        mov     %edx, %eax
        incl    %edx
        cmpl    %edx, %ecx
        movl    %esi, (%rdi,%rax,4)
        jne     .L4
----------------
and this at -O2 -fno-ivopts
----------------
.L4:
        mov     %edx, %eax
        incl    %edx
        cmpl    %ecx, %edx
        movl    %esi, (%rdi,%rax,4)
        jb      .L4
----------------

That means we get the same bad code there in both cases :-(
