|
|
# Much of the complexity here is for supporting cross-building.
|
|
# If a tree does not support that, simply using plain Makefile.depend
|
|
# should provide sufficient clue.
|
|
# Otherwise the recommendation is to use Makefile.depend.${MACHINE}
|
|
# as expected below.
|
|
|
|
# Note: this file gets multiply included.
|
|
# This is what we do with DIRDEPS
|
|
|
|
# DIRDEPS:
|
|
# This is a list of directories - relative to SRCTOP, it is
|
|
# normally only of interest to .MAKE.LEVEL 0.
|
|
# In some cases the entry may be qualified with a .<machine>
|
|
# or .<target_spec> suffix (see TARGET_SPEC_VARS below),
|
|
# for example to force building something for the pseudo
|
|
# machines "host" or "common" regardless of current ${MACHINE}.
|
|
#
|
|
# All unqualified entries end up being qualified with .${TARGET_SPEC}
|
|
# and partially qualified (if TARGET_SPEC_VARS has multiple
|
|
# entries) are also expanded to a full .<target_spec>.
|
|
# The _DIRDEP_USE target uses the suffix to set TARGET_SPEC
|
|
# correctly when visiting each entry.
|
|
#
|
|
# The fully qualified directory entries are used to construct a
|
|
# dependency graph that will drive the build later.
|
|
#
|
|
# Also, for each fully qualified directory target, we will search
|
|
# using ${.MAKE.DEPENDFILE_PREFERENCE} to find additional
|
|
# dependencies. We use Makefile.depend (default value for
|
|
# .MAKE.DEPENDFILE_PREFIX) to refer to these makefiles to
|
|
# distinguish them from others.
|
|
#
|
|
# Before each Makefile.depend file is read, we set
|
|
# DEP_RELDIR to be the RELDIR (path relative to SRCTOP) for
|
|
# its directory, and DEP_MACHINE etc according to the .<target_spec>
|
|
# represented by the suffix of the corresponding target.
|
|
#
|
|
# Since each Makefile.depend file includes dirdeps.mk, this
|
|
# processing is recursive and results in .MAKE.LEVEL 0 learning the
|
|
# dependencies of the tree wrt the initial directory (_DEP_RELDIR).
|
|
#
|
|
# TARGET_SPEC_VARS
|
|
# The default value is just MACHINE, and for most environments
|
|
# this is sufficient. The _DIRDEP_USE target actually sets
|
|
# both MACHINE and TARGET_SPEC to the suffix of the current
|
|
# target so that in the general case TARGET_SPEC can be ignored.
|
|
#
|
|
# If more than MACHINE is needed then sys.mk needs to decompose
|
|
# TARGET_SPEC and set the relevant variables accordingly.
|
|
# It is important that MACHINE be included in and actually be
|
|
# the first member of TARGET_SPEC_VARS. This allows other
|
|
# variables to be considered optional, and some of the treatment
|
|
# below relies on MACHINE being the first entry.
|
|
# Note: TARGET_SPEC cannot contain any '.'s so the target
|
|
# triple used by compiler folk won't work (directly anyway).
|
|
#
|
|
# For example:
|
|
#
|
|
# # Always list MACHINE first,
|
|
# # other variables might be optional.

|
# TARGET_SPEC_VARS = MACHINE TARGET_OS
