 # The user-driven targets are:
 #
 # universe            - *Really* build *everything* (buildworld and
 #                       all kernels on all architectures).  Define
 #                       MAKE_JUST_KERNELS or WITHOUT_WORLDS to only build kernels,
 #                       MAKE_JUST_WORLDS or WITHOUT_KERNELS to only build userland.
 # tinderbox           - Same as universe, but presents a list of failed build
 #                       targets and exits with an error if there were any.
 # worlds	      - Same as universe, except just makes the worlds.
 # kernels	      - Same as universe, except just makes the kernels.
 # buildworld          - Rebuild *everything*, including glue to help do
 #                       upgrades.
 # installworld        - Install everything built by "buildworld".
 # world               - buildworld + installworld, no kernel.
 # buildkernel         - Rebuild the kernel and the kernel-modules.
 # installkernel       - Install the kernel and the kernel-modules.
 # installkernel.debug
 # reinstallkernel     - Reinstall the kernel and the kernel-modules.
 # reinstallkernel.debug
 # kernel              - buildkernel + installkernel.
 # kernel-toolchain    - Builds the subset of world necessary to build a kernel
 # kernel-toolchains   - Build kernel-toolchain for all universe targets.
 # doxygen             - Build API documentation of the kernel, needs doxygen.
 # checkworld          - Run test suite on installed world.
 # check-old           - List obsolete directories/files/libraries.
 # check-old-dirs      - List obsolete directories.
 # check-old-files     - List obsolete files.
 # check-old-libs      - List obsolete libraries.
 # delete-old          - Delete obsolete directories/files.
 # delete-old-dirs     - Delete obsolete directories.
 # delete-old-files    - Delete obsolete files.
 # delete-old-libs     - Delete obsolete libraries.
 # targets             - Print a list of supported TARGET/TARGET_ARCH pairs
 #                       for world and kernel targets.
 # toolchains          - Build a toolchain for all world and kernel targets.
 # makeman             - Regenerate src.conf(5)
 # sysent              - (Re)build syscall entries from syscalls.master.
 # xdev                - xdev-build + xdev-install for the architecture
 #                       specified with TARGET and TARGET_ARCH.
 # xdev-build          - Build cross-development tools.
 # xdev-install        - Install cross-development tools.
 # xdev-links          - Create traditional links in /usr/bin for cc, etc
 # native-xtools       - Create host binaries that produce target objects
 #                       for use in qemu user-mode jails.  TARGET and
 #                       TARGET_ARCH should be defined.
 # native-xtools-install
 #                     - Install the files to the given DESTDIR/NXTP where
 #                       NXTP defaults to /nxb-bin.
 #
 # This makefile is simple by design. The FreeBSD make automatically reads
 # the /usr/share/mk/sys.mk unless the -m argument is specified on the
 # command line. By keeping this makefile simple, it doesn't matter too
 # much how different the installed mk files are from those in the source
 # tree. This makefile executes a child make process, forcing it to use
 # the mk files from the source tree which are supposed to DTRT.
 #
 # Most of the user-driven targets (as listed above) are implemented in
 # Makefile.inc1.  The exceptions are universe, tinderbox and targets.
 #
 # If you want to build your system from source, be sure that /usr/obj has
 # at least 6 GB of disk space available.  A complete 'universe' build of
 # r340283 (2018-11) required 167 GB of space.  ZFS lz4 compression
 # achieved a 2.18x ratio, reducing actual space to 81 GB.
 #
 # For individuals wanting to build from the sources currently on their
 # system, the simple instructions are:
 #
 # 1.  `cd /usr/src'  (or to the directory containing your source tree).
 # 2.  Define `HISTORICAL_MAKE_WORLD' variable (see README).
 # 3.  `make world'
 #
 # For individuals wanting to upgrade their sources (even if only a
 # delta of a few days):
 #
 #  1.  `cd /usr/src'       (or to the directory containing your source tree).
 #  2.  `make buildworld'
 #  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
 #  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
 #       [steps 3. & 4. can be combined by using the "kernel" target]
 #  5.  `reboot'        (in single user mode: boot -s from the loader prompt).
 #  6.  `mergemaster -p'
 #  7.  `make installworld'
 #  8.  `mergemaster'            (you may wish to use -i, along with -U or -F).
 #  9.  `make delete-old'
 # 10.  `reboot'
 # 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)
 #
 # For individuals wanting to build from source with GCC from ports, first
 # install the appropriate GCC cross toolchain package:
 #   `pkg install ${TARGET_ARCH}-gccN`
 #
 # Once you have installed the necessary cross toolchain, simply pass
 # CROSS_TOOLCHAIN=${TARGET_ARCH}-gccN while building with the above steps,
 # e.g., `make buildworld CROSS_TOOLCHAIN=amd64-gcc6`.
 #
 # The ${TARGET_ARCH}-gccN packages are provided as flavors of the
 # devel/freebsd-gccN ports.
 #
 # See src/UPDATING `COMMON ITEMS' for more complete information.
 #
 # If TARGET=machine (e.g. powerpc, arm64, ...) is specified you can
 # cross build world for other machine types using the buildworld target,
 # and once the world is built you can cross build a kernel using the
 # buildkernel target.
 #
 # Define the user-driven targets. These are listed here in alphabetical
 # order, but that's not important.
 #
 # Targets that begin with underscore are internal targets intended for
 # developer convenience only.  They are intentionally not documented and
 # completely subject to change without notice.
 #
 # For more information, see the build(7) manual page.

 # Building a world goes through the following stages
 #
 # 1. legacy stage [BMAKE]
 #	This stage is responsible for creating compatibility
 #	shims that are needed by the bootstrap-tools,
 #	build-tools and cross-tools stages. These are generally
 #	APIs that tools from one of those three stages need to
 #	build that aren't present on the host.
 # 1. bootstrap-tools stage [BMAKE]
 #	This stage is responsible for creating programs that
 #	are needed for backward compatibility reasons. They
 #	are not built as cross-tools.
 # 2. build-tools stage [TMAKE]
 #	This stage is responsible for creating the object
 #	tree and building any tools that are needed during
 #	the build process. Some programs are listed during
 #	this phase because they build binaries to generate
 #	files needed to build these programs. This stage also
 #	builds the 'build-tools' target rather than 'all'.
 # 3. cross-tools stage [XMAKE]
 #	This stage is responsible for creating any tools that
 #	are needed for building the system. A cross-compiler is one
 #	of them. This differs from build tools in two ways:
 #	1. the 'all' target is built rather than 'build-tools'
 #	2. these tools are installed into TMPPATH for stage 4.
 # 4. world stage [WMAKE]
 #	This stage actually builds the world.
 # 5. install stage (optional) [IMAKE]
 #	This stage installs a previously built world.

 # bootstrap-tools: Build tools needed for compatibility. These are binaries that
 # are built to build other binaries in the system. However, the focus of these

 # libraries, augmented by -legacy, in addition to the libraries built during
 # bootstrap-tools.
 #
 _bt=		_bootstrap-tools
 
 # We want to run the build with only ${WORLDTMP} in $PATH to ensure we don't
 # accidentally run tools that are incompatible but happen to be in $PATH.
 # This is especially important when building on Linux/MacOS where many of the
 # programs used during the build accept different flags or generate different
 # output. On those platforms we only symlink the tools known to be compatible
 # (e.g. basic utilities such as mkdir) into ${WORLDTMP} and build all others
 # from the FreeBSD sources during the bootstrap-tools stage.
 # We want to build without the user's $PATH starting in the bootstrap-tools
 # phase so the tools used in that phase (ln, cp, etc) must have already been
 # linked to $WORLDTMP. The tools are listed in the _host_tools_to_symlink
 # variable in tools/build/Makefile and are linked during the legacy phase.
 # Since they could be Linux or MacOS binaries, too we must only use flags that
 # are portable across operating systems.
 
 # If BOOTSTRAP_ALL_TOOLS is set we will build all the required tools from the
 # current source tree. Otherwise we create a symlink to the version found in
 # $PATH during the bootstrap-tools stage.
 # When building on non-FreeBSD systems we can't assume that the host binaries
 # accept compatible flags or produce compatible output. Therefore we force
 # BOOTSTRAP_ALL_TOOLS and just build the FreeBSD version of the binary.

 # In the following, the first 'rm' in a series will usually remove all
 # files and directories.  If it does not, then there are probably some
 # files with file flags set, so this unsets them and tries the 'rm' a
 # second time.  There are situations where this target will be cleaning
 # some directories via more than one method, but that duplication is
 # needed to correctly handle all the possible situations.  Removing all
 # files without file flags set in the first 'rm' instance saves time,
 # because 'chflags' will need to operate on fewer files afterwards.
 #
 # It is expected that BW_CANONICALOBJDIR == the CANONICALOBJDIR as would be
 # created by bsd.obj.mk, except that we don't want to .include that file
 # in this makefile.  We don't do a cleandir walk if MK_AUTO_OBJ is yes
 # since it is not possible for files to land in the wrong place.
