Dunno what export actually does -- drivers/acpi/Makefile has been this way for many years. I believe that -Os is the right way to build the ACPI code. I see that src/Makefile now has ifdef CONFIG_CC_OPTIMIZE_FOR_SIZE KBUILD_CFLAGS += -Os else KBUILD_CFLAGS += -O2 endif so maybe we are now being redundant? > > +ACPI_CFLAGS := -Os > > + > > +ifdef CONFIG_ACPI_DEBUG > > + ACPI_CFLAGS += -DACPI_DEBUG_OUTPUT > > +endif > > + > > +EXTRA_CFLAGS += $(ACPI_CFLAGS) > A better way: > > ccflags-$(CONFIG_ACPI_DEBUG) := -DACPI_DEBUG_OUTPUT > > Note: EXTRA_CFLAGS is deprecated in favour of ccflags-y. can do. thanks, Len Brown, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
