So the bug is not reported upstream. If it's not required for gcc6, then perhaps we should add a BR2_TOOLCHAIN_GCC_AT_LEAST_6 condition, so that this chunk gets a chance to be removed at some point in the future. > +# gcc bug internal compiler error: in merge_overlapping_regs, at regrename.c:304 > +ifeq ($(BR2_microblaze),y) I.e.: ifeq ($(BR2_microblaze):$(BR2_TOOLCHAIN_GCC_AT_LEAST_6),y:) > +VLC_CONF_ENV += CFLAGS="$(TARGET_CFLAGS) -O0" > +VLC_CONF_OPTS += --disable-optimizations > +endif Thanks, Thomas

Override gcc optimization flags with -O0. The workaround is not required for gcc6 anymore, but gcc6 is disabled for microblaze, because it breaks startup of the system somehow. So the bug is not reported upstream.
