- Determine KERN_AS automatically depending on whether OPT_MODULAR is
set or not, in the same way as libcompat.

- Specify OPT_MODULAR in the port Makefile instead of KERN_AS.

Now, KERN_AS=library is used for kernels without module(7) for all ports.

OK christos

- Allow multiple .BEGIN targets

We use .BEGIN for our own cleanup and won't ever need DTS support - so
avoid inclusion of dts.mk by defining _SKIP_DTS

Default kernel builds to USE_SSP=yes.

Ignore unused arguments for clang as we pass assembler flags and the

not known to clang accordingly.

Revert previous, not needed after sys/conf/Makefile.kern.inc rev. 1.215.

We preprocess .s files, so add ${INCLUDES} to AFLAGS

Need assym.h for libkern

Explicitly set KERN_AS (this could be done in /usr/src/sys/conf/Makefile.*)
so that modules work, on config files that did not set it explicitly. All
the files now use the standard logic, except the ones that set KERN_AS=obj
and Makefile.usermode which sets KERN_AS=library.

Add assym.h dependencies.

Refactor in_cksum/in4_cksum/in6_cksum implementations:
- All three functions are included in the kernel by default.
They call a backend function cpu_in_cksum after possibly
computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
The default implementation is moderate fast on most platforms
and provides a 32bit accumulator with 16bit addends for L32 platforms
and a 64bit accumulator with 32bit addends for L64 platforms.
It handles edge cases like very large mbuf chains (could happen with
native IPv6 in the future) and provides a good base for new native
implementations.
- Modify i386 and amd64 assembly to use the new interface.

This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

instead of specifying the start of the data section in the makefile,

Convert existing ath users to new Makefile, except for amd64, which needs
the rules due to needing to conditionally postprocess the HAL object file.

Macppc needs a a non-ELF HAL (EABI) object, so take care of that by default
in the atheros include file.

Reorganize ath layout as requested by sam@ and suggested by dyoung@ in
http://mail-index.netbsd.org/tech-net/2006/03/15/0000.html.

The new layout almost precisely matches FreeBSD, and should make
future imports much easier.

At the same time, import the current 0.9.16.16 HAL from FreeBSD. According
to sam@, this is the proper version we should be using.

Remove workarounds for bugs in the old compiler.

The traditional C preprocessor is fixed in GCC 3.3 now, so no need
to skip -traditional-cpp for HAVE_GCC3.

put an explicit .MAIN target before the .if make() condition; apparently
.MAIN must be defined for the implicit target rule to kick in
this fixes compilation with call like 'make', i.e. without specified target

another option would be to move the .if make() condition after config(8)
generated goo, since config(8) implicitly generates a .MAIN: directive too,
but the MD .if make() really belongs into (7) misc settings section IMHO

create a "sparc" symlink as well. sync kernels.

Don't use -traditional-cpp if HAVE_GCC3.

branches: 1.45.4;
Fix up compiler options:

1) Get things right for 32-bit kernels

2) Always use medium any memory model for 64-bit kernels for the moment.

Roll the rest of the ports over to the new MI kernel build machinery.
Any problems reported by testers have been fixed, and massive
cross-compiling of kernels has shown that any problems that remain
with actually building kernels are not related to this.

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

branches: 1.42.2;
Change defaults for kernel compiles. Default all to USETOOLS?=no and have
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.

Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.

Per request of mrg@netbsd.org, use MACHINE_ARCH of "sparc" for 32-bit
sparc64 kernels, thus defaulting to using the 32-bit "sparc" target
toolchain.

Clean up the 32-bit vs. 64-bit kernel configuration stuff:
- Put all options necessary to build a 64-bit kernel into std.sparc64-64,
which can be included after std.sparc64.
- Change the logic used to enable 64-bit kernels. The kernel Makefile now
uses an LP64 make variable, and explicitly sets compiler flags and linker
scripts to generate 32-bit or 64-bit kernels.

Warning police. Mostly useless format warnings. Switch Makefile for
kernel compiles to the warning flags that other ports also use.

Separate user and kernel address spaces and move the kernel down to
0x0000000001000000 -- 0x00000000f0000000, below the PROM where the
PROM thinks we should be.

Get kernel profiling to work. Now if only gprof worked....

Er, eliminate the -p link option as well, which just outputs huge amounts
of spooge.

Nuke lderr.

Slight rearrangement.

Separate COPTS from CFLAGS to fix problems w/unoptimized files, and add
lfs_loop.c to the list that breaks optimization.

Override optimization for files that break gcc.

branches: 1.23.2;
Add "install" target, so "make install" after building the kernel
does something useful. The target can be redefined by putting a
install-kernel-${MACHINE_NAME} target that fits your needs into
/etc/mk.conf.

Make /etc/mk.conf optional for kernel builds.

copy the "sparc" clean/cleandir target code, so that "cleandir" actually does a "clean"

don't use -Wuninitialized

Fix a couple more references to STRIPPROG.

Use STRIP instead of STRIPPROG since install uses STRIP and I don't want to
define two different variables.

Add "dependall" target for comfort.

STRIP -> STRIPPROG

Change STRIPFLAGS=-g for cross-toolchains.

Switch libkern back to a library 'cause bzero's back in locore.s.

Move KERNBASE down from 0xf8000000 to 0xf1000000, just beyond the PROM.

be more efficient when doing the SYSTEM_LD_TAIL for -g kernels: don't

Switch over to NetBSD/sparc ELF for 32-bit userland.

clean up a bit after jason :)

- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
$INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.

this makes "prefix" actually work in a usable manner, and now i can move
on to fixing compiler warnings (errors) in the ESP code. :)

only set LD to /usr/ccs/bin/ld if it exists. avoid empty SFILES.

branches: 1.8.4;
remove lderr in "make clean"

Add -Wpointer-arith warning since `void *' arithmetic is not ANSI C.

change handling of libkern:
-sys/lib/libkern builds as library per default (as it was documented all
the time)
-ports able to LKM set "KERN_AS=obj" explicitely in their Makefiles
(for now; should depend on actual "option LKM" or -better- functions
included for LKM use should be pulled in by a stub)
-always link libcompat before libkern - libkern stuff can be referred to
by libcompat, but not the other way

Periodic update: now starts probing devices.

- use UVM by default.
- clean up the Makefile a bit to be less solaris-centric :)
- add support for compat_sparc32 (32bit compat module for NetBSD/sparc). this
isn't yet fully tested but it mostly written and compiles if not totally
links yet.

Merge paddr_t changes into the main branch.

allow ${SIZE} to be set from the environment, also allow using genassym.sh (both for cross compiling).
