27# Much of the complexity here is for supporting cross-building.
28# If a tree does not support that, simply using plain Makefile.depend
29# should provide sufficient clue.
30# Otherwise the recommendation is to use Makefile.depend.${MACHINE}
31# as expected below.
32
33# Note: this file gets multiply included.
34# This is what we do with DIRDEPS
35
36# DIRDEPS:
37#	This is a list of directories - relative to SRCTOP, it is
38#	normally only of interest to .MAKE.LEVEL 0.
39#	In some cases the entry may be qualified with a .<machine>
40#	or .<target_spec> suffix (see TARGET_SPEC_VARS below),
41#	for example to force building something for the pseudo
42#	machines "host" or "common" regardless of current ${MACHINE}.
43#
44#	All unqualified entries end up being qualified with .${TARGET_SPEC}
45#	and partially qualified (if TARGET_SPEC_VARS has multiple
46#	entries) are also expanded to a full .<target_spec>.
47#	The  _DIRDEP_USE target uses the suffix to set TARGET_SPEC
48#	correctly when visiting each entry.
49#
50#	The fully qualified directory entries are used to construct a
51#	dependency graph that will drive the build later.
52#
53#	Also, for each fully qualified directory target, we will search
54#	using ${.MAKE.DEPENDFILE_PREFERENCE} to find additional
55#	dependencies.  We use Makefile.depend (default value for
56#	.MAKE.DEPENDFILE_PREFIX) to refer to these makefiles to
57#	distinguish them from others.
58#
59#	Each Makefile.depend file sets DEP_RELDIR to be the
60#	the RELDIR (path relative to SRCTOP) for its directory, and
61#	since each Makefile.depend file includes dirdeps.mk, this
62#	processing is recursive and results in .MAKE.LEVEL 0 learning the
63#	dependencies of the tree wrt the initial directory (_DEP_RELDIR).
64#
65# BUILD_AT_LEVEL0
66#	Indicates whether .MAKE.LEVEL 0 builds anything:
67#	if "no" sub-makes are used to build everything,
68#	if "yes" sub-makes are only used to build for other machines.
69#	It is best to use "no", but this can require fixing some
70#	makefiles to not do anything at .MAKE.LEVEL 0.
71#
72# TARGET_SPEC_VARS
73#	The default value is just MACHINE, and for most environments
74#	this is sufficient.  The _DIRDEP_USE target actually sets
75#	both MACHINE and TARGET_SPEC to the suffix of the current
76#	target so that in the general case TARGET_SPEC can be ignored.
77#
78#	If more than MACHINE is needed then sys.mk needs to decompose
79#	TARGET_SPEC and set the relevant variables accordingly.
80#	It is important that MACHINE be included in and actually be
81#	the first member of TARGET_SPEC_VARS.  This allows other
82#	variables to be considered optional, and some of the treatment
83#	below relies on MACHINE being the first entry.
84#	Note: TARGET_SPEC cannot contain any '.'s so the target
85#	triple used by compiler folk won't work (directly anyway).
86#
87#	For example:
88#
89#		# Always list MACHINE first,
90#		# other variables might be optional.
91#		TARGET_SPEC_VARS = MACHINE TARGET_OS
92#		.if ${TARGET_SPEC:Uno:M*,*} != ""
93#		_tspec := ${TARGET_SPEC:S/,/ /g}
94#		MACHINE := ${_tspec:[1]}
95#		TARGET_OS := ${_tspec:[2]}
96#		# etc.
97#		# We need to stop that TARGET_SPEC affecting any submakes
98#		# and deal with MACHINE=${TARGET_SPEC} in the environment.
99#		TARGET_SPEC =
100#		# export but do not track
101#		.export-env TARGET_SPEC
102#		.export ${TARGET_SPEC_VARS}
103#		.for v in ${TARGET_SPEC_VARS:O:u}
104#		.if empty($v)
105#		.undef $v
