things like the .note.netbsd.ident section are provided by crti/crtn.
crti/crtn also provide the _init() and _fini() routines.
crtbegin/crtend now only provide support for ctors/dtors. This paves
the way to using the "crtstuff" provided with GCC (when we upgrade to
GCC 3.3), which provides, among other things, much better C++/Java
exception handling.
and the sources now use that define, so there is no need for us to define
ABICALLS. Since that was the only use for the AINC variable, garbage-collect
it.
-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.
The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler
uses, which is what is used for things in e.g. xsrc, pkgsrc, and other
random 3rd party programs.
This is done by decoupling where a shlib is installed from how it
is located. Two new variables, SHLIBINSTALLDIR and SHLINKINSTALLDIR,
contain the former information, and key off MKDYNAMICROOT only. SHLIBDIR
and SHLINKDIR contain the latter, and key off MKDYNAMICROOT and BINDIR.
The SHLIBINSTALLDIR, SHLIBDIR, _LIBSODIR, SHLINKINSTALLDIR, and
SHLINKDIR parameters are moved to a new <bsd.shlib.mk>; see bsd.README
for usage details.
-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.
The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler

random 3rd party programs.
This means that:
+ /bin and /sbin (and the few programs in /usr/* which were statically
linked) are now dynamically linked.
+ The shared libraries that are needed by the /bin and /sbin programs
are now installed into /lib (with compatability symlinks from
/usr/lib). These are:
c crypt edit ipsec kvm m m387 termcap termlib util z
+ The shared linker is now in /libexec/ld.elf_so, and
/usr/libexec/ld.elf_so is a symlink to the former.
If you want the prior behaviour of "some applications statically linked,
the rest dynamically linked", set MKDYNAMICROOT=no in your mk.conf(5).
If you have a philosophical objection to dynamic libraries, continue
to set LDSTATIC=-static in your mk.conf(5), and please don't waste any
more time in trying to convince us why dynamic libraries are 3v1l.
two variables:
TOOLCHAIN_MISSING -- set to "yes" on platforms for which there is
no working in-tree toolchain (hppa, ns32k, sh5, x86_64).
EXTERNAL_TOOLCHAIN -- if defined by the user, points to the root of
an external toolchain (e.g. /usr/local/gnu). This enables the cross-build
framework even for TOOLCHAIN_MISSING platforms.
If TOOLCHAIN_MISSING is set to "yes", MKGDB, MKBFD, and MKGCC are all
unconditionally set to "no", since the bits are not there to build.
If EXTERNAL_TOOLCHAIN is set, MKGCC is unconditionally set to "no",
since the external toolchain's compiler is not in-sync with the
in-tree compiler support components (e.g. libgcc).

be changed in the future to "yes".
If MKDYNAMICROOT == "no", there is no change from existing behaviour
of a static /bin and /sbin (and a few programs in elsewhere).
If MKDYNAMICROOT == "yes", the following changes occur:

SHLIBDIR?= /lib
SHLINKDIR?= /lib

This results in all programs (except those "standalone" programs built
in sys/arch/*/stand) are linked dynamically, the shared linker is moved
from /usr/libexec to /lib (with a compat symlink), and the shared
libraries used by /bin and /sbin programs are moved from /usr/lib to
/lib (with compat symlinks).
as they default to using install(1) -r.
the rm can cause problems in certain situations, such as moving a library or
shared linker that install(1) depends upon to another location and replacing
it with a (sym)link.
* Don't make OBJECT_FMT dependent on USE_NEW_TOOLCHAIN. All ports
except ns32k are ELF, so set it appropriately. Allow it to be
overridden in the ns32k case.
* If ns32k && USE_NEW_TOOLCHAIN, don't build shared libraries, because
external toolchains don't support them for our a.out.
* If ns32k && OBJECT_FMT == ELF, the GNU platform is "netbsdelf".
* If ns32k && USE_NEW_TOOLCHAIN, don't attempt to build the in-tree
binutils 2.11.2, gdb 5.0, or gcc 2.95.3.
This allows us to do USE_NEW_TOOLCHAIN cross-builds to ns32k using
an external toolchain.
There were too many synchronisation problems with using the former;
including situations such as a "make clean" performed between two
installs to the same DESTDIR would result in a truncated METALOG and
the resultant sets would be missing stuff such as include files that
don't get reinstalled if they haven't changed, even with !UPDATE.
Sources for a target do not accumulate over dependency lines
when this operator is used.
An unstated implication of this is that when parallel builds are done,
each separate instance of the target can be scheduled independantly.
As a result, the linksinstall target with commands could be executed
too early during a parallel build since they didn't actually have a
dependancy on "realinstall".
To fix this, correct the linksinstall:: realinstall dependancy by
eliminating the command-less linksinstall target, and moving the
dependancy to the other linksinstall target.
Defaults to the directory determined by the _SRC_TOP_ logic (if != ""),

NETBSDSRCDIR has been provided for use by the various NetBSD source
Makefiles to find the top of the NetBSD source tree, and isn't
affected by the inheritance properties of _SRC_TOP_, nor does it
have the magic BSDOBJDIR baggage that BSDSRCDIR is stuck with.
determined, since BSDSRCDIR's default of /usr/src might not exist and the
calculation of _SRC_TOP_OBJ_ would then generate a warning :-(.
_SRC_TOP_ can now == "" if make(1) (or a parent make(1)) was started
outside of the NetBSD source tree.
Now, if _SRC_TOP_ != "", BSDSRCDIR defaults to ${_SRC_TOP_} and
BSDOBJDIR defaults to the objdir of ${BSDSRCDIR}.
Failsafe defaults for BSDSRCDIR (/usr/src) and BSDOBJDIR (/usr/obj)
are provided later in the file.
This should result in a usable BSDSRCDIR default (i.e, _SRC_TOP_ if
running from within the source tree), with safe fallbacks as appropriate
(/usr/src, as always), meaning that BSDSRCDIR should be able to be used
instead of _SRC_TOP_ in the source tree, although I need to carefully
test this. *aaaiiiieeee!!!*. (Now I understand some of Todd's pain :)

The net effect of these changes depends on how the variables are set:
1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so
2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so
3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed
it (kernel and libc).
The current version of the gas assembler in the tree (2.11.2) already
defaults to generating object files for "-Av9 -64", supporting V9
instructions in ELF64 object format. "-Av9a" is only needed for specific
parts of the NetBSD base sources, and not for all third-party code.
Wrap assignments of various tools within USETOOLS_BINUTILS and
USETOOLS_GCC (names reflect the FSF packages the tools are provided

of these packages.
can be specified in mk.conf: AR, AS, LD, NM, OBJCOPY, OBJDUMP,
RANLIB, SIZE, and STRIP.
This, along with some symlinks in TOOLDIR, makes it much easier to
test different versions of the GNU toolchain (e.g. binutils-current).
as it calls troff/etc without any leading pathnames. Otherwise the tools
version is fairly useless as the installed system version will be used to
build all manpages
The dependency should be against the TOOLDIR files (is USETOOLS=yes) but
installs will always use ${DESTDIR}/usr/share/tmac.
Without this if people do not have /usr/share/tmac/tmac.andoc on their
systems while building the build will break in the groff areas due to
the dependency rules.
i.e. if the root of the object tree doesn't exist then complain and exit.
This makes both sections consistant to each other (MAKEOBJDIR specifies an
exact directory so there's no root per se to check so nothing can really be
done there).
Use the old setup for MAKEOBJDIRPREFIX but also add a new check for
_SRC_TOP_OBJ_ and use that if it's set. This allows a make release using
build.sh (which uses MAKEOBJDIR patterns) to function correctly on r/o
source tree's.
INSTALL_FILE does.
2) Patch around a bug that has been biting people in which bsd.own.mk
attempts to cd into space when building outside of the tree. I may
have a better solution for the whole thing later.
make bsd.lib.mk use INSTALL_SYMLINK instead of mv and ln -s.
Note: There is still one weird case I left alone, in which symlinks
get built in the objdir. I didn't want to log metadata for those links
so I left the old machinery in for them.
XXX do we even need that elaborate dance for the ln's in the objdir?
0) rename UNPRIVILEGED UNPRIVED. It was too long. We'll argue about if
we should replace it with yet something else later. It currently
logs metadata by default. We'll argue more about that later too.
1) create a _SRC_TOP_OBJ_ variable pointing at the /usr/src objdir so
we know where to dump metadata.
2) Add a METALOG variable pointing at the default location for the
metadata log. (This may be moved or renamed -- the location is just
for testing.)
3) Add a HOST_INSTALL_FILE used in host tools Makefiles instead of
INSTALL_FILE, which doesn't include ${INSTPRIV} (i.e -U -M ${METALOG})
4) Add INSTALL_LINK, INSTALL_SYMLINK for use in other .mk files so we
can get rid of explicit uses of ln. Slightly clean up INSTALL_FILE.
It is infeasible for some ARM ports to use anything but ELF/new-toolchain,
and this allows for the ARM ports that aren't ready for ELF to stay at
MACHINE_ARCH == arm32 until they're ready. The rest of the ARM ports
have a userbase such that if a flag day happens with the compiler (there
are a couple of ABI issues still being discussed), that it won't matter
so much.

* Remove the MKTOOLS logic. This was linked to the "make build" hack,

* Redo the GNU configure/make logic to make it fit reasonably in a
BSD make wrapper. Use new ${.ALLTARGETS} variable to scan for
targets in $(srcdir), and mark them with .MADE: to prevent rebuilding.
* Only build cross tools in src/tools; remove some messy logic in
src/usr.* and src/gnu/usr.* that would do target filename rewriting
(improves consistency and readability).
* Add the ability to build cross gdb at tool build time by setting
