https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94969 --- Comment #8 from bin cheng --- Root cause is in build_classic_dist_vector -> constant_access_functions which adds unit distance vector only in case of constant access function. It should cover invariant cases. Testing a patch. Thanks

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94969 --- Comment #6 from Richard Biener --- Before Richards change we likely gave up on the mismatch in access function dimensionality for f[b] vs. f[b].e but now we compute a dependence distance of zero.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94969 --- Comment #5 from Richard Biener --- So I think the issue is not dependence testing but loop distribution accepting a zero dependence distance as OK. Of course dependence analysis is quite useless here since the accesses are to the same locati
