This is meant to install a new BE (boot environment) given a fully built
world/kernel. In addition to installing world and kernel in the new BE,
it also automatically performs /etc updates (using etcupdate or mergemaster)
and package updates (using pkg).
Because this process is performed in a new BE, it reduces the need for a
second reboot. It also means a reboot into a partially updated system (due
to install or hardware failure) can't happen.

This will still build the compiler for the target but will not build the
bootstrap cross-compiler in the cross-tools phase. Other toolchain
bootstrapping, such as elftoolchan and binutils, currently still occurs.
This will utilize the default CC (cc, /usr/bin/cc) as an external compiler.
This is planned to be on-by-default eventually.
This will utilize the __FreeBSD_cc_version compiler macro defined in the
source tree and compare it to CC's version. If they match then the
cross-compiler is skipped. If [X]CC is an external compiler (absolute
path) or WITHOUT_CROSS_COMPILER is already set, then this logic is skipped.
If the expected bootstrap compiler type no longer matches the found CC
compiler type (clang vs gcc), then the logic is skipped. As an extra
safety check the version number is also compared from the compiler to
the tree version.
Clang:
The macro FREEBSD_CC_VERSION is defined in:
lib/clang/include/clang/Basic/Version.inc
For clang -target will be used if TARGET_ARCH != MACHINE_ARCH. This
is from the current external toolchain logic. There is currently an
assumption that the host compiler can build the TARGET_ARCH. This
will usually be the case since we don't conditionalize target arch
support in clang, but it will break when introducing new
architectures. This problem is mitigated by incrementing the version
when adding new architectures.
GCC:
The macro FBSD_CC_VER is defined in:
gnu/usr.bin/cc/cc_tools/freebsd-native.h
For GCC there is no simple -target support when TARGET_ARCH !=
MACHINE_ARCH. In this case the opportunistic skip is not done. If we
add proper support for this case in external toolchain logic then it
will be fine to enable.
This relies on the macros being incremented whenever any change occurs
to these compilers that warrant rebuilding files. It also should never
repeat earlier values.

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 dramatic time savings with a full cache.

This speeds up buildworld by 16% on my system and buildkernel by 35%.
Rather than calling mkdep(1), which is just a wrapper around 'cc -E',
use the modern -MD -MT -MF flags to gather and generate dependencies during
compilation. This flag was introduced in GCC "a long time ago", in GCC 3.0,
and is also supported by Clang. (It appears that ICC also supports this but I
do not have access to test it). This avoids running the preprocessor *twice*
for every build, in both 'make depend' and 'make all'. This is especially
noticeable when using ccache since it does not cache preprocessor results from
mkdep(1) / 'cc -E', but still speeds up compilation with the -MD flags.
For 'make depend' a tree-walk is still done to ensure that all DPSRCS
are generated when expected, and that beforedepend/afterdepend and
_EXTRADEPEND are all still respected. In time this may change but for now
I've been conservative. The time for a tree-walk with -j combined with
SUBDIR_PARALLEL is not significant. For example, it takes about 9 seconds
with -j15 to walk all of src/ for 'make depend' now on my system.
A .depend file is still generated with the various rules that apply to
the final target, or custom rules. Otherwise there are now
per-built-object-file .depend files, such as .depend.filename.o. These
are included directly by make rather than populating .depend with a loop
and .depend lines, which only added overhead to the now almost-NOP 'make
depend' phase.
Before this I experimented with having mkdep(1) called in parallel per-file.
While this improved the kernel and lib/libc 'make depend' phase, it resulted
in slower build times overall.
The -M flags are removed from CFLAGS when linking since they have no effect.
Enabling this by default, for src or out-of-src, can be done once more testing
has been done, such as a ports exp-run, and with more compilers.

Also add a stdlib.h wrapper, which declares the function, otherwise the
compiler may assume it returns int, which can cause segfaults on LP64
architectures.

Clang's OpenMP support will emit Intel OpenMP API library calls,
and will therefore require libiomp (or whatever name is settled on).
An up-to-date version of libgomp is included in ports or pkg GCC.
Thus, there is no reason to build base libgomp without base system GCC.

pwrite(2) syscalls are wrapped to provide compatibility with pre-7.x
kernels which required padding before the off_t parameter. The
fcntl(2) contains compatibility code to handle kernels before the
struct flock was changed during the 8.x CURRENT development. The
shims were reasonable to allow easier revert to the older kernel at
that time.
Now, two or three major releases later, shims do not serve any
purpose. Such old kernels cannot handle current libc, so revert the
compatibility code.
Make padded syscalls support conditional under the COMPAT6 config
option. For COMPAT32, the syscalls were under COMPAT6 already.
Remove WITHOUT_SYSCALL_COMPAT build option, which only purpose was to
(partially) disable the removed shims.

I was originally planning on removing the phase-of-moon (pom), clock
(grdc), and caesar cipher (caesar, rot13) utilities as well, but after
I committed r278616 I received an astonishing volume of email informing
me that those are still being widely used. Much to my relief, nobody
reported continuing to use the punch card utilities in production.
The final step will be to merge src/games into src/usr.bin.

update paths; and include everything in the "base" distribution.
The "games" distribution being optional made sense when there were more
games and we had small disks; but the "games-like" games were moved into
the ports tree a dozen years ago and the remaining "utility-like" games
occupy less than 0.001% of my laptop's small hard drive. Meanwhile every
new user is confronted by the question "do you want games installed" when
they they try to install FreeBSD.
The next steps will be:
2. Removing punch card (bcd, ppt), phase-of-moon (pom), clock (grdc), and
caesar cipher (caesar, rot13) utilities. I intend to keep fortune, factor,
morse, number, primes, and random, since there is evidence that those are
still being used.
3. Merging src/games into src/usr.bin.
This change will not be MFCed.
