From: Evgeniy Didin Date: Tue, 14 Nov 2017 05:59:56 +0000 (+0300) Subject: fwup: fix for ARC toolchain X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9d544feb8a277a43abec889450f917017d666e49;p=buildroot.git fwup: fix for ARC toolchain Building fwup package with ARC toolchain causes internal compiler error. Adding patch for ARC gcc solves this issue. In the next version of toolchain, this problem has already been taken into account.
