built-in.o

好像是有 Makefile 的 folder，依照Makefile 和 Kconfig .config 的內容，會將有用到的 *.o link 成 built-in.o 然後最後 再把所有的 built-in.o link 成 vmlinux built-in.o 的 Make rule 在 scripts/Makefile.build ifdef builtin-target quiet_cmd_link_o_target = LD $@ # If the list of objects to link is empty, just create an empty built-in.o cmd_link_o_target = $(if $(strip $(obj-y)),\ $(LD) $(ld_flags) -r -o $@ $(filter $(obj-y), $^) \ $(cmd_secanalysis),\ rm -f $@; $(AR) rcs $@) $(builtin-target): $(obj-y) FORCE $(call if_changed,link_o_target) targets += $(builtin-target) endif # builtin-target
