Constant fold shifts, turning this loop:

.LBB_Z5test0PdS__3:     # no_exit.1
        fldl data(,%eax,8)
        fldl 24(%esp)
        faddp %st(1)
        fstl 24(%esp)
        incl %eax
        movl $16000, %ecx
        sarl $3, %ecx
        cmpl %eax, %ecx
        fstpl 16(%esp)
        #FP_REG_KILL
        jg .LBB_Z5test0PdS__3   # no_exit.1

into:

.LBB_Z5test0PdS__3:     # no_exit.1
        fldl data(,%eax,8)
        fldl 24(%esp)
        faddp %st(1)
