--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.  Trunk aligns stuff:

fact:
.LFB0:
        .cfi_startproc
        testl   %edi, %edi
        movl    $1, %eax
        je      .L4
        .p2align 4,,10
        .p2align 3
.L3:
        imull   %edi, %eax
        subl    $1, %edi
        jne     .L3
        rep ret
        .p2align 4,,10
        .p2align 3
.L4:
        rep ret
        .cfi_endproc

this all is probably a BB reorder / cfg cleanup issue.
