[Bug tree-optimization/61980] ICE: in compute_affine_dependence, at tree-data-ref.c:4233 with -fcheck-data-deps


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61980

--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
It's intended for debugging only:

@item -fcheck-data-deps
@opindex fcheck-data-deps
Compare the results of several data dependence analyzers.  This option
is used for debugging the data dependence analyzers.
