--- Comment #13 from Christophe Lyon <clyon at gcc dot gnu.org> ---
I have noticed that this patch (r254758) causes errors on several tests, for
instance:
c-c++-common/builtin-arith-overflow-2.c
target: arm-none-linux-gnueabi
--with-mode thumb
--with-cpu cortex-a9
and using -march=armv5t in the runtest flags/target board
spawn -ignore SIGHUP
