From 6838495a88684e69c130cff58f96d5a78bf0e1c7 Mon Sep 17 00:00:00 2001 From: Giulio Benetti Date: Sat, 8 Apr 2023 20:45:59 +0200 Subject: [PATCH] package/matio: fix build failure due to gcc bug 99410 The matio package exhibits gcc bug 99410 when built for the Nios2 architecture with optimization enabled, which causes a build failure. As done for other packages in Buildroot work around this gcc bug by setting optimization to -O0 if BR2_TOOLCHAIN_HAS_GCC_BUG_99410=y.
