In fact there are other regressions in this code (+ is 3.3's asm and - is 3.4's asm) (random4 
function):
-.L11:
        cmpl    %edi, %esi
-       jae     .L10
+       jae     .L11
+.L9:
        call    random4
        movzbl  .LC0(%eax), %eax
        movb    %al, (%ebx)
        incl    %ebx
        incl    %esi
-       jmp     .L11
-.L10:
+       cmpl    %edi, %esi
+       jb      .L9
+.L11:
