By default, the bootonce setting is reset on attempt to boot and the next
boot will use previously active BE.
By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will

bootonce dataset name is recorded in boot pool labels, bootenv area.
in case of nextboot, the nextboot_enable boolean variable is recorded in

On boot, the loader will process /boot/nextboot.conf if nextboot_enable

processing on next boot.
bootonce and nextboot features are usable in both UEFI and BIOS boot.

Use of ranlib or lorder is no longer necessary with current linkers
(probably anything newer than ~1990) and ar's ability to create an object
index and symbol table in the archive.
Currently the build system uses lorder+tsort to sort the .o files in
dependency order so that a single-pass linker can use them. However,
we can use the -s flag to ar to add an index to the .a file which makes
lorder unnecessary.
Running ar -s is equivalent to running ranlib afterwards, so we can also
skip the ranlib invocation.
Similarly, we don't have to pass the .o files for shared libraries in
dependency order since both ld.bfd and ld.lld will correctly resolve
references between the .o files.
This removes many fork()+execve calls for each library so should speed up
builds a bit. Additionally lorder.sh uses a regular expression that is not
supported by the macOS libc or glibc and results in many warnings when
cross-building (see D25989).
There is one functional change: lorder.sh removed duplicated .o files
from the linker command line which now no longer happens. I fixed the duplicates
in the base system in r364649. I also checked the ports tree for uses of
bsd.lib.mk and found one duplicate source file which I fixed in r548168.
Most ports use CMake/autotools rather than bsd.lib.mk but if this breaks any
ports that I missed in my search please let me know.
Avoiding the shell script actually speeds up the linking step noticeably: I
measured how long it takes to rebuild the .a and .so files for lib/libc using a
basic benchmark: `rm $LIBC_OBJDIR/*.so* $LIBC_OBJDIR/*.a* && /usr/bin/time make -DWITHOUT_TESTS -s > /dev/null`
Without this change ~4.5 seconds and afterwards ~3.1 seconds.
Looking at truss -cf output we can see that the number fork() system
calls goes down from 27 to 12 (and the speedup while tracing is more
noticeable: 81 seconds -> 65 seconds).
See also https://www.gnu.org/software/coreutils/manual/html_node/tsort-background.html
for some more background:
This whole procedure has been obsolete since about 1980, because Unix
archives now contain a symbol table (traditionally built by ranlib, now
generally built by ar itself), and the Unix linker uses the symbol table
to effectively make multiple passes over an archive file.
Or alternatively https://www.unix.com/man-page/osf1/1/lorder/:
The lorder command is essentially obsolete. Use the following command in
its place: % ar -ts file.a

- Support for complex netmap options, such as external memory

extensions.
- More flexibility in the netmap port bind options, such as

I noticed that when we build libraries for a different ABI (in CheriBSD) we
were calling ${XCC}/${LD} --version for every directory. It turns out that
this was caused by bsd.compat.mk explicitly setting (X_)COMPILER variables
for that build stage and this stops the _can_export logic from working.
To fix this, we change the check to only set _can_export=no if the variable
is set and it is set to a different value than the cached value.
This noticeably speeds up the tree walk while building compat libraries.
During an upstream amd64 buildworld this also removes 8 --version calls.

When using relative paths for the linker we have to transform the name
since clang does not like -fuse-ld=ld.lld and instead requires -fuse-ld=lld
(the same also applies for ld.bfd).
This is needed so that setting LD/XLD is not ignored when linking with $CC
instead of directly using $LD. Currently only clang accepts an absolute
path for -fuse-ld= (Clang 12+ will add a new --ld-path flag), so we now
warn when building with GCC and $LD != "ld" since that might result in the
wrong linker being used.
We have been setting XLD=/path/to/cheri/ld.lld in CheriBSD for a long time and
used a similar version of this patch to avoid linking with /usr/bin/ld.
This change is also required when building FreeBSD on an Ubuntu with Clang:
In that case we set XCC=/usr/lib/llvm-10/bin/clang and since
/usr/lib/llvm-10/bin/ does not contain a "ld" binary the build fails with
`clang: error: unable to execute command: Executable "ld" doesn't exist!`
unless we pass -fuse-ld=/usr/lib/llvm-10/bin/ld.lld.
This change passes -fuse-ld instead of copying ${XLD} to WOLRDTMP/bin/ld
since then we would have to ensure that this file does not exist while
building the bootstrap tools. The cross-linker might not be compatible with
the host linker (e.g. when building on macos: host-linker= Mach-O /usr/bin/ld,
cross-linker=LLVM ld.lld).

Save and restore (also known as suspend and resume) permits a snapshot
to be taken of a guest's state that can later be resumed. In the
current implementation, bhyve(8) creates a UNIX domain socket that is
used by bhyvectl(8) to send a request to save a snapshot (and
optionally exit after the snapshot has been taken). A snapshot
currently consists of two files: the first holds a copy of guest RAM,
and the second file holds other guest state such as vCPU register
values and device model state.
To resume a guest, bhyve(8) must be started with a matching pair of
command line arguments to instantiate the same set of device models as
well as a pointer to the saved snapshot.
While the current implementation is useful for several uses cases, it
has a few limitations. The file format for saving the guest state is
tied to the ABI of internal bhyve structures and is not
self-describing (in that it does not communicate the set of device
models present in the system). In addition, the state saved for some
device models closely matches the internal data structures which might
prove a challenge for compatibility of snapshot files across a range
of bhyve versions. The file format also does not currently support
versioning of individual chunks of state. As a result, the current
file format is not a fixed binary format and future revisions to save
and restore will break binary compatiblity of snapshot files. The
goal is to move to a more flexible format that adds versioning,
etc. and at that point to commit to providing a reasonable level of
compatibility. As a result, the current implementation is not enabled
by default. It can be enabled via the WITH_BHYVE_SNAPSHOT=yes option
for userland builds, and the kernel option BHYVE_SHAPSHOT.

Now that LLD 10 is out, and required patches have landed, we are now ready
to finally switch away from the ancient in-tree ld.bfd.
Special thanks to Fangrui Song for many hours of work on getting the
32-bit powerpc lld ready for prime-time.

Original commit message:
bsd.lib.mk: Do not include bsd.incs.mk for INTERNALLIB
f we're building an internal lib do not bother including bsd.incs.mk so we
will not install the headers.
This also "solves" a problem with pkgbase where a libXXX-development package
is created and due to how packages are created we add a dependency to a
libXXX package that doesn't exists.

Delete the conditions that forcibly disabled GOOGLETEST and LLDB for

Also delete the complicated method of defaulting LIBCPLUSPLUS to YES.

We no longer support older C++ compilers, so do not need to explicitly
test for C++11 support.
After r339946 we stopped running `cc --version` during cleandir/obj
stages, so stopped setting COMPILER_FEATURES. This in turn meant
lib/libomp was excluded from the clean stage in a normal buildworld
(i.e., one without -DNO_CLEAN), and this is what caused recent build
failures with errors about missing ittnotify_static.c.
This commit should obviate the need for the workaround committed in
r359083. Thanks to bdrewery for the insight and for pushing for a
correct fix. There are more cleanups to be done, but this change is
a simplification and an improvement over r359083.

This allows simplification of Makefiles where some SUBDIR entries depend
on two things (e.g. something that depends on C++ and some other knob).

The vectx API, computes the hash for verifying a file as it is read.
This avoids the overhead of reading files twice - once to verify, then
again to load.
For doing an install via loader, avoiding the need to rewind
large files is critical.
This API is only used for modules, kernel and mdimage as these are the
biggest files read by the loader.
The reduction in boot time depends on how expensive the I/O is
on any given platform. On a fast VM we see 6% improvement.
For install via loader the first file to be verified is likely to be the
kernel, so some of the prep work (finding manifest etc) done by
verify_file() needs to be factored so it can be reused for
vectx_open().
For missing or unrecognized fingerprint entries, we fail
in vectx_open() unless verifying is disabled.
Otherwise fingerprint check happens in vectx_close() and
since this API is only used for files which must be verified
(VE_MUST) we panic if we get an incorrect hash.

Now that we no longer have GCC 4.2.1 in the tree and can assume FreeBSD
is being built with a C++11 compiler available, we can use BSDL dtc
unconditionally and retire the GPL dtc.
GPL dtc now has FreeBSD CI support via Cirrus-CI to help ensure it
continues to build/work on FreeBSD and is available in the ports tree
if needed.
The copy of (copyfree licensed) libfdt that we actually use is in
sys/contrib/libfdt so the extra copy under contrib/dtc/libfdt can be
removed along with the rest of the GPL dtc.

With the retirement of GCC 4.2.1 we can assume the host compiler supports
C++11, and can simplify the Clang and LLD defaults. Clang and lld are now
enabled by default everywhere, and are used as the bootstrap compiler and
linker for all targets except MIPS.

As described in Warner's email message[1] to the FreeBSD-arch mailing
list we have reached GCC 4.2.1's retirement date. At this time all
supported architectures either use in-tree Clang, or rely on external
toolchain (i.e., a contemporary GCC version from ports).
GCC 4.2.1 was released July 18, 2007 and was imported into FreeBSD later
that year, in r171825. GCC has served us well, but version 4.2.1 is
obsolete and not used by default on any architecture in FreeBSD. It
does not support modern C and does not support arm64 or RISC-V.
Thanks to everyone responsible for maintaining, updating, and testing
GCC in the FreeBSD base system over the years.
So long, and thanks for all the fish.

Binutils has already been reduced to installing ld only on powerpc32
and as only on amd64. (Also objdump on every arch supported by binutils
2.17.50.) Although BINUTILS_BOOTSTRAP serves no purpose on MIPS there
is no reason to have a special case for it.
