Before this commit, all arch/arm/cpu/${CPU}/config.mk except ARMv8 had the same option: $(call cc-option,-mshort-load-bytes,$(call cc-option,-malignment-traps,)) This commit moves it into arch/arm/config.mk. If the compiler does not support the option, it is ignored by $(call cc-option,...). So this commit gives no harm to ARMv8. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> --- FYI: gcc 3.4.6 Manaul says -mno-alignment-traps Generate code that assumes that the MMU will not trap unaligned accesses. This produces better code when the target instruction set does not have half-word memory operations (i.e. implementations prior to ARMv4). Note that you cannot use this option to access unaligned word objects, since the processor will only fetch one 32-bit aligned object from memory. The default setting is -malignment-traps, since this produces code that will also run on processors implementing ARM architecture version 6 or later. This option is deprecated and will be removed in the next release of GCC.
