That is worse than the existing entries. Do you really want to replace
ifsel(CONFIG_SLIP_COMPRESSED)
select(CONFIG_SLIP slhc.o)
endif
with this?
ifeq(,$(findstring n,$(CONFIG_SLIP_COMPRESSED)$(CONFIG_SLIP))
ifneq(,$(findstring m,$(CONFIG_SLIP_COMPRESSED)$(CONFIG_SLIP)))
# compile as module
else
# compile builtin
endif
endif
I was hoping to compress the existing three lines to one.
select_cond(CONFIG_SLIP_COMPRESSED CONFIG_SLIP slhc.o)
The more standardized formats there are in kbuild, the harder it is for
users to make mistakes. What they expand to behind the scenes is a
seperate question. BTW, the test that handles 'n' as well as '' is
ifneq ($(subst n,,$(CONFIG_FOO)$(CONFIG_BAR)),)
