Sorry for typing too fast... Of course, load of %ebp is here:

foo:
        pushl   %ebp
        pushl   %edi
        pushl   %esi
        pushl   %ebx
        subl    $1032, %esp
        leal    8(%esp), %ebp            <<<<<<< load of %ebp
        movl    1052(%esp), %eax
        andl    $15, %eax
        shrl    $2, %eax
        negl    %eax
        andl    $3, %eax
        je      .L2
        movl    $0, %ecx
.L4:
        movl    1052(%esp), %edx
        movl    %ebp, (%edx,%ecx,4)

And just for fun, without vectorization, following code is produced:

foo:
        subl    $1024, %esp
        movl    1028(%esp), %ecx
        movl    %esp, %edx
        movl    $1, %eax
.L2:
        movl    %edx, -4(%ecx,%eax,4)
        incl    %eax
        cmpl    $11, %eax
        jne     .L2
        addl    $1024, %esp
        ret
