Subject: fix isl_qpolynomial_fold_reset_dim
X-Git-Tag: isl-0.04~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f0a93a211d458c17f0333d136f3288a30698ade0;p=platform%2Fupstream%2Fisl.git

fix isl_qpolynomial_fold_reset_dim

In particular, the old version wouldn't cow and it wouldn't change
the dimension of the nested isl_qpolynomials.
