#	This Makefiles contains the common targets and definitions for
#	all kernels. It is to be included in the Makefiles for specific
#	implementation architectures and processor architecture dependent
#	modules: i.e.: all driving kernel Makefiles.

#

#
#	All C objects depend on inline files. However, cc(1) doesn't generate
#	the correct dependency info. Also, these Makefiles don't contain a
#	separate list of C-derived object files (but it is light weight to
#	let the assembler files think they depend upon this when they don't).
#	Fortunately, the inline files won't change very often. So, for now,
#	all objects depend on the inline files. Remove this when the inliner
#	is fixed to drop correct dependency information.
#
$(OBJECTS): $(INLINES)

#
#	Partially link .o files to generate the kmod. The fake dependency
#	on modstubs simplifies things...
#	ELFSIGN_MOD is defined in the individual KCF plug-in modules Makefiles,
#	and will sign the ELF objects using elfsign(1).
