Subject: the array D for the diagonal matrix in Hessian isn't needed for l2_loss problems
X-Git-Tag: v211~15
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c1b10b56a104d92a16ce255fd140c1ef686ce82b;p=liblinear

the array D for the diagonal matrix in Hessian isn't needed for l2_loss problems
so we remove it. It's now only used for lr.
