I understood that this patch will let us set ASFLAGS from the command-line. You mentioned CFLAGS because that's how we could indirectly set ASFLAGS, right? If so, looks good to me. >> --- a/Makeconfig >> +++ b/Makeconfig >> @@ -1047,7 +1047,7 @@ endif >> ifndef ASFLAGS >> ASFLAGS := $(filter -g% -fdebug-prefix-map=%,$(CFLAGS)) >> endif >> -ASFLAGS += -Werror=undef $(ASFLAGS-config) $(asflags-cpu) >> +override ASFLAGS += -Werror=undef $(ASFLAGS-config) $(asflags-cpu) >> >> ifndef BUILD_CC >> BUILD_CC = $(CC) > >Ping?

Correct, but it also affects compilation of C sources, so it is not always desirable to use this. > If so, looks good to me. Thanks for the review! Florian
