From 7c7c0e4406aea45b2db0a932b128960b4ef4b474 Mon Sep 17 00:00:00 2001 From: Giulio Benetti Date: Tue, 25 Jun 2019 09:02:54 +0200 Subject: [PATCH] package/git: 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 git with optimization but not when building with -O0. To work around this, if BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y we force using -O0.
