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
buildworld.

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

* Building the big llvm, clang and lldb libraries as shared (private)

* Adding other components from the LLVM project, such as lld.
There were a few issues.
- In-tree GCC won't have X_COMPILER_TYPE defined but will have
WANT_COMPILER_TYPE==gcc set from the SYSTEM_COMPILER logic that can
be used. Make the clang check specific to clang as well to ensure
-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

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.

- The -L WORLDTMP/usr/lib is not needed as GCC is already adding in
-L =/usr/lib internally with --sysroot. It does not do this for
header include paths though, thus passing -isystem =/usr/include is
still needed.
For the forced libc++ usage:
- Use -isystem rather than -I for libc++ headers.
- Use -std=c++11 rather than gnu++11.
- Use -nostdinc++ to ensure GCC's headers don't leak in.

This overrides the cross-compiler's default sysroot to use the WORLD32's
sysroot for building the lib32 libraries. Previously the cross-compiler
would default the sysroot to the 64bit WORLDTMP and -B/-L/-isystem flags
were used to build using the lib32 files. This leads to multiple issues
discussed later. Some extra headers are now needed to be staged since the
64bit WORLDTMP is not referenced at all for headers. The 64bit WORLDTMP
is still used via PATH for build tools. Overriding the default
target/arch is retained in the CC/CXX overrides.
This allows reverting the LDSCRIPT rewriting in installworld from r296921 and
r235122, thus allowing read-only objdirs to work for installing again.
This removes the need for _LDSCRIPTROOT.
This allows progressing the change to always use --sysroot for the build

profile, development, debug, or any combination of the four.
This created significant overhead when adding new packages

Instead of test(1)-ing if the <packagename>.ucl file exists,

This is to fix 'make all' causing it to recurse on both 'all' and 'buildconfig'
due to 'buildconfig' being in ALL_SUBDIR_TARGETS and being a dependency of
'all'.
This now adds all of the '*includes', '*files' targets as subdir targets,
allowing them to recurse.
This also removes the need for some 'realinstall' hacks in bsd.subdir.mk since
it no longer recurses; only 'install' will recurse and call the proper
'beforeinstall', 'realinstall', and 'afterinstall' in each sub-directory.
This fixes 'make includes' and 'make files' to not be a rerolled ${MAKE}
sub-shell but to rather just recurse on 'inclues' and 'files'. This avoids
various issues such as the one fixed in r289462. As such revert Makefile.inc1
back to using 'includes' which avoids an extra tree walk and parallelizes
the includes phases better.
Makefile.inc1 includes a guard so that 'make all' will not use SUBDIR_PARALLEL,
added in r289438. This is so users do not get a probably broken build if they
run 'make all' from the top-level. Before the change in this commit, the
workaround for 'make everything' was 'par-all' which would depend on 'all' and
cause a proper parallel recursion. Now that will not work so a new
_PARALLEL_SUBUDIR_OK is used to allow it.
This is still part of an effort to combine bsd.(files|incs|confs).mk and move
some of its logic out of bsd.subdir.mk, as attempted in r289282 and reverted in
r289331. This commit fixes the problems found there which was mostly double
recursing during 'includes' which would recurse on itself and 'buildincludes'
and 'installincludes', all in parallel. The logic is still in bsd.subdir.mk
for now.
I've been cautious about this commit but have experienced no breakage on the
tree except for the 'par-all' case which was already a hack. If something foo
is depending on something bar that should recurse, it is very likely that the
foo target is being recursed on already meaning that bar will still effectively
recurse once sub-directories call foo.

Say it with me, "I will not chain commands with && in Makefiles"
This was originally fixed and explained quite well by bde@ in r36074. The
initial bmake integration caused 'set -e' to stop being used which lead to
r252419. Later 'set -e' expectations were fixed with bmake in r254980.
Because of the && here, errors would be ignored when building in parallel and
a dependency failed. Such as bootstrap-tools since it builds everything in
parallel. If any tool failed in obj/depend/all, it would just ignore the error
and continue to build. This later would result in cascaded errors that only
confused the real issue. This could also cause commands after the failed
command to still execute, leading to more confusion.
This should be fine if the command is in a sub-shell such as: (cmd1 && cmd2)

The bootstrap-tools are supposed to be host tools, which in most cases, use

During the target build in buildworld the target headers are staged into
