Looks like the classic data dependence test can be improved:
A[0] does not overlap with A[1], and so there is no dependence:
Data ref a:
#(Data Ref:
# bb: 6
# stmt: points[D.2720_36][0] = start$0_8(D);
# ref: points[D.2720_36][0];
# base_object: points
# Access function 0: 0
# Access function 1: (int) {0, +, 1}_2;
#)
Data ref b:
#(Data Ref:
# bb: 6
# stmt: points[D.2720_36][1] = D.2723_40;
# ref: points[D.2720_36][1];
# base_object: points
# Access function 0: 1
# Access function 1: (int) {0, +, 1}_2;
#)
affine dependence test not usable: access function not affine or constant.
(dependence classified: scev_not_known)
)

--- Comment #3 from Sebastian Pop <spop at gcc dot gnu.org> 2011-02-01 23:28:33 UTC ---
I think that the problem is (again) the type of the induction variables that we
create in graphite: in pr33866.c we have
D.2720_37 = (int) graphite_IV.5_34;
and this (int) confuses the data reference analysis.

More specifically, the code that is now confused by the (int) cast is:
dr_analyze_innermost (dr);
dr_analyze_indices (dr, nest, loop);
in create_data_ref.

There might be overlap with PR47341 (also casts that confuse dependency info)?

Is this fixable for the 4.6.0 release or would that be to invasive for stage 4?

Checking the failures in vect.exp at r176905 with -fgraphite-identity enabled
at -O2, we seem to have picked up a bunch for -flto at -m32 on
x86_64-apple-darwin11...
