libl is needed for config(8), which is a bootstrap-tool. It is possible to
build a system WITHOUT_TOOLCHAIN to exclude lex and thus, libl. We still
need to support building from this kind of host, though.

explanation. These can likely both be scoped more clearly, but this will

r335653 flipped the order in which hints/env files are concatenated to match
the order in which vars are processed by the kernel. This is the other
hammer to drop.
Use nv(9) to de-dupe entries within a single `hint` or `env` file, using the
latest value specified for a key. This leaves some duplicates if a variable
is specified in multiple hint/env files or via `envvar` in a kernel config,
but the reversed order of concatenation (from r335653) makes this a
non-issue as the latest-specified version will be seen first.
This change also silently rewrote hint bits to use the same sanitization
process that ian@ wrote for r335642. To the kernel, hints and env vars are
basically the same thing through early boot, then get merged into the
dynamic environment once kmem becomes available and the dynamic environment
is created. They should be subjected to the same restrictions.
libnv has been added to -legacy for the time being to support the build of
config(8) with the new cnvlist API.

Currently the mtree calls in Makefile.inc1 all change the directory owner
to match the spec file. However, we should not be doing this during
distributeworld if -DNO_ROOT is passed. Additionally, when creating the
WORLDTMP directory hierachy there is no need to change the owner to root so
we now always pass the -W flag when populating WORLDTMP.
This is also required for building FreeBSD on Linux/Mac since the required

This works similar to WITH_SYSTEM_COMPILER added in r300354. It only
supports lld via WITH_LLD_BOOTSTRAP.
When both SYSTEM_COMPILER and SYSTEM_LINKER logic passes then libclang
will not build in cross-tools. If either check fails though then
libclang is built.
The .info is reworked to notify when libclang will be built since if
either clang or lld needs to be rebuilt, but not the other, the
notification can lead to confusion on why "clang is building".
-fuse-ld= is not used with this method so some combinations of compiler
and linker are expected to fail.
A new 'make test-system-linker' target is added to see the logic results.
Makefile.inc1:
CROSS_BINUTILS_PREFIX support had to be moved higher up so that XLD
could be set and MK_LLD_BOOTSTRAP disabled before checking SYSTEM_LINKER
logic as done with SYSTEM_COMPILER. This also required moving where
bsd.linker.mk was read since XLD needs to be set before parsing it. This
creates a situation where src.opts.mk can not test LINKER_FEATURES or
add LLD_BOOTSTAP to BROKEN_OPTIONS.

9.3 is the final 9.x release and does not contain the r286035 fix.
10.3 is the first 10.x release with the fix. Thus, in practice 10.3 is

MAKEOBJDIR, and MAKELEVEL=1 in the environment. This causes the mm-mtree makes
to not do some basic setup of OBJROOT and only use this special
MAKEOBJDIRPREFIX case which fails to empty out MAKEOBJDIRPREFIX for further
nested makes, such as a tree walk. If that tree walk sets OBJROOT/OBJTOP such

This takes longer but should reliably produce working binaries.
The old version linked against system libraries and headers
which would be a problem if building a native-xtools against
a newer source than the host system. With a proper sysroot made
first this is not a problem.
This also allows:
- NXBDIRS to be built in parallel
- NXBDIRS to be installed to NXBDESTDIR in parallel
- SYSTEM_COMPILER logic to work again. Note that because this change
is adding a sysroot phase the compiler may be built up to twice now.
The first is the "cross-compiler" even though it is for the native
architecture, but it is still built to ensure the latest compiler
is used to generate the binaries, unless SYSTEM_COMPILER allows
/usr/bin/cc to be used. Then the target compiler is built
which is actually a cross-compiler since it runs on native host
but generates TARGET.TARGET_ARCH binaries.
Note this also changes the path used for the OBJDIR. It used to use
/usr/obj/target.target_arch/nxb/<srcdir> for objects and

- NXBDESTDIR can be specified for where to install or queried with
`make -f Makefile.inc1 TARGET=... TARGET_ARCH=... -V NXBDESTDIR`
This could potentially be improved to reuse an existing sysroot. The
problem is with building the SUBDIR_OVERRIDE list it needs to use a
different OBJDIR since it is building all statically. We don't want to
pollute the existing 'buildworld' OBJDIR and cause confusion on the next
build. Using a separate OBJDIR for the 'everything' phase mostly works
except for some things like linking in INTERNALLIBS that exist in the
other OBJDIR.

The idea here is that, provided upstream pkg(8) maintainers accept
the proposed change, the kernel.ucl will contain a post-install

new userland is installed on the running new kernel. At present,
this functionality does not exist in pkg(8), but will help ensure
the upgrade path follows that from UPDATING. To work around this
for now, evaluate ASSUME_ALWAYS_YES, and prompt the user if they
wish to proceed if not set to true.

Normally META_MODE ignores host files for "meta mode" decisions on whether a
file should be rebuilt or not. This is because a simple installworld can
update timestamps and cause the next build to rebuild all host tools, when the
previous ones may not have any changes in the source tree. These tools are
normally still ABI compatible. They are only rebuilt if NO_META_IGNORE_HOST is
set from the workaround/hack in r301467.
One of the major problems with this is when a host tool has objects spread
across many revisions that have mixed-ABI. For example, if struct stat were to
change on the host, some objects for a tool may have different ideas of that
struct's definition. If just 1 source file were modified and rebuilt and
linked into the tool, then that toll will have mixed-ABI objects and crash.
This exact thing happened with the ino64 commit in r301467 followed by a
trivial update to libbfd in r318750. The resulting binary would crash in

FreeBSD does not guarantee kernel forward compatibility (that is,
running a newer userland on an older kernel). The documented upgrade
procedure specifies that installkernel should be performed, followed by
a reboot and then installworld. As a sanity check when installing onto
the running system (DESTDIR is / or unset), attempt to run "sh echo OK"
using rescue from the objdir. If rescue fails (e.g., because the system
has not been rebooted and the "old" kernel lacks a system call required
by the to-be-installed world), abort the installation.
This should avoid ino64 foot-shooting when the proper upgrade procedure
is not followed.

Right after cross-tools, a compiler-metadata.mk file is created that
stores all of the bsd.compiler.mk metadata. It is then read in
with a fail-safe during installworld time.
The file is explicitly removed when invoking cross-tools to ensure that
a stale file is not left around from odd manual 'make _cross-tools' ->
'make installworld' invocations.
This fixes several issues:
- With WITH_SYSTEM_COMPILER (default yes on head and no on releng/11.0):
If you build on a system where the bootstrap compiler does not
build due to the host compiler matching the in-tree one, but then
installworld on another system where that logic fails (a
bootstrap compiler is needed), the installworld immediately fails
with:
sh: cc: not found
Note that fixing this logic may then hit a case where a rebuild is
attempted in installworld. Normally cc would be ran with
'CFLAGS+=ERROR-tried-to-rebuild-during-make-install' to cause an
error such as:
cc: error: no such file or directory: 'ERROR-tried-to-rebuild-during-make-install'
However, now it will just fail with the 'cc: not found' error.
Inspection of the compile line will show
'ERROR-tried-to-rebuild-during-make-install'; It's not useful to
set CC to anything other than 'cc' during install as it is more
helpful to see the attempted compile rather than some other bogus
error.
- This now avoids running bsd.compiler.mk (cc executions) even more
during installworld. There are compiler-dependent SUBDIR in the
tree which required having a compiler during install.
There is at least 1 case where CC is still executed in the install,
such as from a LOOKUP!= in secure/lib/libcrypto/Makefile.inc checking
for 'vzeroall' support. This is not significant for installworld
as the lookup has a fallback (and hides its error) and only modifies CFLAGS,
thus it's not worth fixing.

In a cross-build, the build-tools are native host binaries. We do not
want to rebuild them when building for the target. Bmake previously
did not support checking .NOMETA on an existing target, so .NOMETA_CMP
was used here. However, .NOMETA_CMP still triggers meta mode conditions
if the number of commands or the command changes. In r312467 the paths
to build ncurses files were modified and thus triggered meta mode to
rebuild the build tools (make_keys, make_hash) in ncurses during the
target build. Bmake 20160604 committed in r301462 changed .NOMETA to
also skip meta mode logic for an existing .meta file as well, thus it
is now the proper fix here.
I explored moving the build-tools output to WORLDTMP/tools with
relatively good success, but have concerns that doing so would be
problematic for downstream vendors who use LOCAL_TOOL_DIRS and
expect the tools to be in current OBJDIR for the target. It also
adds more complexity into finding the tools during target build
and handling of where they are for rescue/rescue and
mkcsmapper_static/mkesdb_static which should really not be connected in

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

WANT_COMPILER_TYPE==gcc set from the SYSTEM_COMPILER logic that can

-target doesn't leak into a GCC build.
- When using a cross-compiler GCC (with a default sysroot or arch) and also
passing --sysroot, it basically forgets all internal paths for
libraries. We've already worked around this quite a bit for
the external toolchains. Now for the in-tree bootstrap cross-compiler
GCC, also pass in the needed -B${WORLDTMP}/usr/lib to find the crt
object files, but also -isystem and -L to fix the paths. This creates
quite a spammy build log, but it is clear and still achieves the goals
