# Disable unit-at-a-time mode on pre-gcc-4.0 compilers, it makes gcc use
# a lot more stack due to the lack of sharing of stacklots:
- KBUILD_CFLAGS += $(shell if [ $(call cc-version) -lt 0400 ] ; then \
- echo $(call cc-option,-fno-unit-at-a-time); fi ;)
+ KBUILD_CFLAGS += $(call cc-ifversion, -lt, 0400, \

# CPU-specific tuning. Anything which can be shared with UML should go here.
