From 8d8d4ecaf1bc22a89d0f373e9d1655f59f283480 Mon Sep 17 00:00:00 2001 From: Giulio Benetti Date: Tue, 21 May 2019 15:39:26 +0200 Subject: [PATCH] package/glibmm: work around gcc bug 85180 With Microblaze Gcc version < 8.x the build hangs due to gcc bug 85180: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180. The bug shows up when building glibmm with optimization but not when building with -O0. To work around this, if BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y, we force using -O0.
