Re: vectorization, scheduling and aliasing

Hi Richard,

Here is the relevant block from the dump:

<bb 3>:
  __vect_var__26_6 = *__vect_p_14_19;
  *__vect_p_18_25 = __vect_var__26_6;
  # PT = nonlocal { __PARM_RESTRICT_2 } (restr)
  __vect_p_22_11 = __vect_p_14_19 + 8;
  # PT = nonlocal { __PARM_RESTRICT_1 } (restr)
  __vect_p_27_12 = __vect_p_18_25 + 8;
  __vect_var__26_45 = *__vect_p_22_11;
  *__vect_p_27_12 = __vect_var__26_45;

I guess that it recognizes the restrict pointer so I don't understand
why later it creates a dependency between the insns.
Do you see here something relevant?

Thanks, Roy.
