From: Alexey Brodkin Date: Wed, 27 Jul 2016 12:51:32 +0000 (+0300) Subject: toolchain/gcc/arc-2016.03: Fix building on hosts with gcc 6.x X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7cc31b52e11ff19a7e7d467be4c3dc0e5755e7a9;p=openwrt%2Fstaging%2Fyousong.git toolchain/gcc/arc-2016.03: Fix building on hosts with gcc 6.x On attempt to build ARC toolchain on the host with gcc 6.1 I saw the same failure as described in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69959 This change adds a back-port of the fix from upstream gcc, see https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=233572 Note the fix is already a part of gcc-5.4 and gcc-6.1 so no need for the same fix for others.
