Yes, this should get vectorized. The problem is in data dependencies
analysis. We fail to prove that s_5->a[i_16] and s_5->a[i_16] access the
same memory location. I think, it happens since when we compare the bases
of the data references (s_5->a and s_5->a) in base_object_differ_p(), we do
that by comparing the trees (which are pointers) and not their content.
I'll look into this and, I hope, I will submit a fix for that soon (I guess
using operand_equal_p instead).
I hope it helps - we have a lot of them resulting from fairly innocent
Fortran.
I'd be willing to test out your solution privately, if you prefer such a
round first ...
Thanks.
