It was originally written by Sun as part of the STF (Solaris test framework).
They open sourced it in OpenSolaris, then HighCloud partially ported it to
FreeBSD, and Spectra Logic finished the port. We also added many testcases,
fixed many broken ones, and converted them all to the ATF framework. We've had
help along the way from avg, araujo, smh, and brd.
By default most of the tests are disabled. Set the disks Kyua variable to
enable them.

This code, which is basically `svnversion || svnliteversion`, generates
2 fstatat(2) for every directory in PATH for every Makefile parsed that
includes bsd.own.mk. This can add up for things like generating a Ports
index (Poudriere) or building a dependency graph for base.

OK. We don't really need a bsd.stand.mk, and it was causing a -fPIC
for the toolchain to be added (bogusly) when building on amd64. Pull
all relevant defs back into defs.mk and delete bsd.stand.mk.
This saves about 15-20k on i386 loader and zfsloader which when
combined with Lua give us a lot more stack space in those constrained
environments.
liblua glues the lua run time into the boot loader. It implements all
the runtime routines that lua expects. In addition, it has a few
standard 'C' headers that nueter various aspects of the LUA build that
are too specific to lua to be in libsa. Many refinements from the
original code to improve implementation and the number of included lua
libraries. Use int64_t for lua_Number. Have "/boot/lua" be the default
module path. Numerous cleanups from the original GSoC project,
including hacking libsa to allow lua to be built with only one change
outside luaconf.h.
Add the final bit of lua glue to bring in liblua and plug into the
multiple interpreter framework, previously committed.
Add LOADER_LUA option, currently off by default.
Presently, this is an experimental option. One must opt-in to using
this by defining WITH_LOADER_LUA and WITHOUT_FORTH. It's been
lightly tested, so keep a backup copy of your old loader handy.
The menu code, coming in the next commit, hasn't been exhaustively
tested. A LUA boot loader is 60k larger than a FORTH one, which is
80k larger than a no-interpreter one. Subtle changes in size
may tip things past some subtle limit (the binary is ~430k now
when built with LUA). A future version may offer coexistance.

Introduce WITH_/WITHOUT_LLVM_COV to match GCC's WITH_/WITHOUT_GCOV.
It is intended to provide a superset of the interface and functionality
of gcov.
It is enabled by default when building Clang, similarly to gcov and GCC.
This change moves one file in libllvm to be compiled unconditionally.
Previously it was included only when WITH_CLANG_EXTRAS was set, but the
complexity of a new special case for (CLANG_EXTRAS | LLVM_COV) is not
worth avoiding a tiny increase in build time.

libreadline.
Since gdb has been mostly deorbitted in all arches, gdbtui was only installed

libregex is a regex(3) implementation intended to feature GNU extensions and
any other non-POSIX compliant extensions that are deemed worthy.
These extensions are separated out into a separate library for the sake of
not cluttering up libc further with them as well as not deteriorating the
speed (or lack thereof) of the libc implementation.
libregex is implemented as a build of the libc implementation with LIBREGEX
defined to distinguish this from a libc build. The reasons for
implementation like this are two-fold:
1.) Maintenance- This reduces the overhead induced by adding yet another
regex implementation to base.
2.) Ease of use- Flipping on GNU extensions will be as simple as linking
against libregex, and POSIX-compliant compilations can be guaranteed with a
REG_POSIX cflag that should be ignored by libc/regex and disables extensions
in libregex. It is also easier to keep REG_POSIX sane and POSIX pure when
implemented in this fashion.
Tests are added for future functionality, but left disconnected for the time
being while other testing is done.

Another solution would be to extend the Makefile.sys.inc idea, or a .no_obj

Akin to r327783 for amd64. lld has been usable for amd64 for quite some
time, but a couple of issues remained that affected i386. These were
recently addressed upstream in lld and merged into FreeBSD (r326831,
r326879, r326897, r326957), so we can now use ld.lld on i386 as well.
Similarly to amd64 this change enables lld only as the bootstrap linker
(used to link the kernel and userland libraries and executables), while
GNU ld.bfd is still installed as /usr/bin/ld and used for ports builds.
The ports collection is essentially ready to use lld as the system
linker for amd64, but many ports still have trouble with lld on i386,
because lld defaults to -ztext, disallowing relocations against readonly
segments. Thus switching the system linker (WITH_LLD_IS_LD) will happen
later on a per-arch basis.

For some time we have been planning to migrate to LLVM's lld linker.
Having a man page was the last blocking issue for using ld.lld to link
the base system kernel + userland, now addressed by r327770. Link the
kernel and userland libraries and binaries with ld.lld by default, for
additional test coverage.
This has been a long time in the making. On 2013-04-13 I submitted an
upstream tracking issue in LLVM PR 23214: [META] Using LLD as FreeBSD's
system linker. Since then 85 individual issues were identified, and
submitted as dependencies. These have been addressed along with two
and a half years of other lld development and improvement.
I'd like to express deep gratitude to upstream lld developers Rui
Ueyama, Rafael Espindola, George Rimar and Davide Italiano. They put in
substantial effort in addressing the issues we found affecting
FreeBSD/amd64.
To revert to using ld.bfd as the bootstrap linker, in /etc/src.conf set
WITHOUT_LLD_BOOTSTRAP=yes
If you need to set this, please follow up with a PR or post to the
freebsd-toolchain mailing list explaining how default WITH_LLD_BOOTSTRAP
failed for your use case.
Note that GNU ld.bfd is still installed as /usr/bin/ld, and will still
be used for linking ports. ld.lld can be installed as /usr/bin/ld by
setting in /etc/src.conf
WITH_LLD_IS_LLD=yes
A followup commit will set WITH_LLD_IS_LD by default, possibly after
Clang/LLVM/lld 6.0 is merged to FreeBSD.

Several checks assume .CURDIR is resolved, such as for determining RELDIR from
SRCTOP/.CURDIR. If -C is used then the path is no longer resolved like it was
before which is problematic for symlinked source trees. A similar change was
also made to ports post bmake-20170301.
This fixes 'make -C <symlinked path> buildworld' using the wrong OBJDIR.

This will cause an error if the wanted OBJDIR is not writable. Previously it
would cause the files to generate to the source tree. This was too obscure and
things like buildworld really expect a proper OBJDIR layout.

This warning checks whether a constant is out of range of the integer
type. An example is `comparison of 'u_int' > 4294967295 is always false`
and in this case the warning makes sense.
However, when the type is a typedef that can be either 64 or 32 bits the
if condition is only tautological in some configurations so this should
not be a warning that fails the build.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Commit these apart because compile testing doesn't guarantee I didn't made
some nasty mistake. No functional change intended.
This also makes it so that top-level build targets do not immediately create
the OBJDIR. Only sub-make targets will do so. This avoids creating object
directories for targets like 'make check-old' or creating unneeded
MACHINE.MACHINE_ARCH directories during 'make tinderbox'.
