# The user-driven targets are:
#
# universe - *Really* build *everything* (buildworld and
# all kernels on all architectures).
# tinderbox - Same as universe, but presents a list of failed build
# targets and exits with an error if there were any.
# 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.
# update - Convenient way to update your source tree(s).
# 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.
# 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.
#
# "quick" way to test all kernel builds:
# _jflag=`sysctl -n hw.ncpu`
# _jflag=$(($_jflag * 2))
# [ $_jflag -gt 12 ] && _jflag=12
2013-07-07 20:44:04 +00:00
# make universe -DMAKE_JUST_KERNELS JFLAG=-j${_jflag}
#
# 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 6GB of diskspace available. A complete 'universe' build requires
# about 100GB of space.
#
# 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)
#
# See src/UPDATING `COMMON ITEMS' for more complete information.
#
# If TARGET=machine (e.g. powerpc, sparc64, ...) is specified you can
# cross build world for other machine types using the buildworld target,
2002-06-24 05:14:54 +00:00
# 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.

Add built-in ccache build support via WITH_CCACHE_BUILD option. ccache is mostly beneficial for frequent builds where -DNO_CLEAN is not used to achieve a safe pseudo-incremental build. This is explained in more detail upstream [1] [2]. It incurs about a 20%-28% hit to populate the cache, but with a full cache saves 30-50% in build times. When combined with the WITH_FAST_DEPEND feature it saves up to 65% since ccache does cache the resulting dependency file, which it does not do when using mkdep(1)/'CC -E'. Stats are provided at the end of this message. This removes the need to modify /etc/make.conf with the CC:= and CXX:= lines which conflicted with external compiler support [3] (causing the bootstrap compiler to not be built which lead to obscure failures [4]), incorrectly invoked ccache in various stages, required CCACHE_CPP2 to avoid Clang errors with parenthesis, and did not work with META_MODE. The option name was picked to match the existing option in ports. This feature is available for both in-src and out-of-src builds that use /usr/share/mk. Linking, assembly compiles, and pre-processing avoid using ccache since it is only overhead. ccache does nothing special in these modes, although there is no harm in calling it for them. CCACHE_COMPILERCHECK is set to 'content' when using the in-tree bootstrap compiler to hash the content of the compiler binary to determine if it should be a cache miss. For external compilers the 'mtime' option is used as it is more efficient and likely to be correct. Future work may optimize the 'content' check using the same checks as whether a bootstrap compiler is needed to be built. The CCACHE_CPP2 pessimization is currently default in our devel/ccache port due to Clang requiring it. Clang's -Wparentheses-equality, -Wtautological-compare, and -Wself-assign warnings do not mix well with compiling already-pre-processed code that may have expanded macros that trigger the warnings. GCC has so far not had this issue so it is allowed to disable the CCACHE_CPP2 default in our port. Sharing a cache between multiple checkouts, or systems, is explained in the ccache manual. Sharing a cache over NFS would likely not be worth it, but syncing cache directories between systems may be useful for an organization. There is also a memcached backend available [5]. Due to using an object directory outside of the source directory though you will need to ensure that both are in the same prefix and all users use the same layout. A possible working layout is as follows: Source: /some/prefix/src1 Source: /some/prefix/src2 Source: /some/prefix/src3 Objdir: /some/prefix/obj Environment: CCACHE_BASEDIR='${SRCTOP:H}' MAKEOBJDIRPREFIX='${SRCTOP:H}/obj' This will use src*/../obj as the MAKEOBJDIRPREFIX and tells ccache to replace all absolute paths to be relative. Using something like this is required due to -I and -o flags containing both SRC and OBJDIR absolute paths that ccache adds into its hash for the object without CCACHE_BASEDIR. distcc can be hooked into by setting CCACHE_PREFIX=/usr/local/bin/distcc. I have not personally tested this and assume it will not mix well with using the bootstrap compiler. The cache from buildworld can be reused in a subdir by first running 'make buildenv' (from r290424). Note that the cache is currently different depending on whether -j is used or not due to ccache enabling -fdiagnostics-color automatically if stderr is a TTY, which bmake only does if not using -j. The system I used for testing was: WITNESS Build options: -j20 WITH_LLDB=yes WITH_DEBUG_FILES=yes WITH_CCACHE_BUILD=yes DISK: ZFS 3-way mirror with very slow disks using SSD l2arc/log. The arc was fully populated with src tree files and ccache objects.

Create a new MACHINE_ARCH for Freescale PowerPC e500v2 Summary: The Freescale e500v2 PowerPC core does not use a standard FPU. Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processor unit, which doubles as a FPU. The PowerPC SPE ABI is incompatible with the stock powerpc ABI, so a new MACHINE_ARCH was created to deal with this. Additionaly, the SPE opcodes overlap with Altivec, so these are mutually exclusive. Taking advantage of this fact, a new file, powerpc/booke/spe.c, was created with the same function set as in powerpc/powerpc/altivec.c, so it becomes effectively a drop-in replacement. setjmp/longjmp were modified to save the upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible by the SPE). Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does not support double-precision floating point. Also, without a new MACHINE_ARCH it would be impossible to provide binary packages which utilize the SPE. Additionally, no work has been done to support ports, work is needed for this. This also means no newer gcc can yet be used. However, gcc's powerpc support has been refactored which would make adding a powerpcspe-freebsd target very easy. Test Plan: This was lightly tested on a RouterBoard RB800 and an AmigaOne A1222 (P1022-based) board, compiled against the new ABI. Base system utilities (/bin/sh, /bin/ls, etc) still function appropriately, the system is able to boot multiuser.
