--- Comment #18 from Uroš Bizjak <ubizjak at gmail dot com> --- I have committed the bugfix part of the patch [1] to mainline SVN, and will backport it to other release branches. The addition of new VIA CPUs is not a regression fix, so the patch will be applied to mainline only. Please post the patch to the gcc-patches@ mailing list, following the usual contribution rules [2]. [1] https://gcc.gnu.org/ml/gcc-patches/2016-06/msg00044.html [2] https://gcc.gnu.org/contribute.html
