bsd.own.mk: rename to CC_WNO_ADDRESS_OF_PACKED_MEMBER

Provide a single variable
CC_WNO_ADDRESS_OF_PACKED_MEMBER
with options for both clang and gcc, to replace
CLANG_NO_ADDR_OF_PACKED_MEMBER
CC_NO_ADDR_OF_PACKED_MEMBER
GCC_NO_ADDR_OF_PACKED_MEMBER

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

don't error array-bounds and packed-member issues with GCC 9.

- 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

No need to specify COMPAT_AS anymore.
Now, it is automatically determined from OPT_MODULAR.

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.

HAVE_GCC28 -> HAVE_EGCS, and make it match gcc 2.9 as well. Also,
make the use of -Wno-uninitialized explicit, don't rely on a compiler
hack to do it for us.

- 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. :)

Don't define "mc68020". Nothing uses it.

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

Add -Werror and -Wmissing-prototypes, like most other ports do.

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

distclean is a synonym for cleandir

Specify a non-profiling C rule.

Add -Wno-main conditional on compiler being gcc 2.8 or egcs. (This adds
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)

FP in kernel) in CFLAGS.

Move strip(1) flags into a separate variable, so that $STRIP can

Add the %MAKEOPTIONSAPPEND token at the end of the file, after the
common Makefile.kern.inc has been included.

branches: 1.96.6; 1.96.10;
The traditional C preprocessor is fixed in GCC 3.3 now, so no need
to skip -traditional-cpp for HAVE_GCC3.

Don't use -traditional-cpp if HAVE_GCC3.

Get rid of the XDEFS thing; the new toolchain provides a proper
cross compilation environment.

branches: 1.93.8; 1.93.10;
add "-m68030" for sun3x, addresses PR 15312.

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\""

- pull in opt_kgdb.h where necessary
- replace opt_kgdb_machdep.h with opt_kgdb.h
- defparam opt_kgdb.h:
KGDB_DEV KGDB_DEVNAME KGDB_DEVADDR KGDB_DEVRATE KGDB_DEVMODE
- move from opt_ddbparam.h to opt_ddb.h:
DDB_FROMCONSOLE DDB_ONPANIC DDB_HISTORY_SIZE DDB_BREAK_CHAR SYMTAB_SPACE
- replace KGDBDEV with KGDB_DEV
- replace KGDBADDR with KGDB_DEVADDR
- replace KGDBMODE with KGDB_DEVMODE
- replace KGDBRATE with KGDB_DEVRATE
- use `9600' instead of `0x2580' for 9600 baud rate
- use correct quotes for options KGDB_DEVNAME="\"com\""
- use correct quotes for options KGDB_DEV="17*256+0"
- remove unnecessary dependancy on Makefile for kgdb_stub.o
- minor whitespace cleanup

branches: 1.89.2;
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.

branches: 1.88.2;
Set MACHINE_ARCH explicitly in Makefiles for which it is constant.
Also, since config(8) now explcitly sets MACHINE, there is no need
to do it here in the Makefile.

branches: 1.87.2;
define _KERNEL_OPT as well as _KERNEL. we will use this in the future to
get kernel "opt_foo.h" headers, rather than _KERNEL && !_LKM.

branches: 1.86.2;
switch sun3 to ELF. highlight include:
add "%" prefix to register names in assembly code.
change assembly functions to return values in %a0 instead of %d0.
C symbols no longer prepend an underscore, adjust assembly code for this.
32-bit values are now 32-bit aligned instead of 16-bit aligned,
adjust structure packing and padding to override this where necessary.
make EXEC_ELF std, make EXEC_AOUT and COMPAT_AOUT_M68K optional.
use the MI loadfile() instead of several home-grown versions.

Add -D__m68k__ to XDEF.
It is required by sys/compat/linux/common/linux_exec.h.

XXX: -undef is still required?

delete obsolete comment

convert to use genassym.cf & genassym.sh, as other ports do

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.

HAVE_GCC28 -> HAVE_EGCS, and make it match gcc 2.9 as well. Also,
make the use of -Wno-uninitialized explicit, don't rely on a compiler
hack to do it for us.

Revert STRIPPROG -> STRIP

Add "dependall" target for comfort.

STRIP -> STRIPPROG

Change STRIPFLAGS=-g for cross-toolchains.

branches: 1.76.2;
be more efficient when doing the SYSTEM_LD_TAIL for -g kernels: don't
copy them just to strip them, use strip -o.

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. :)

branches: 1.74.4;
Don't define "mc68020". Nothing uses it.

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

Add -Werror and -Wmissing-prototypes, like most other ports do.

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

distclean is a synonym for cleandir

Specify a non-profiling C rule.

Add -Wno-main conditional on compiler being gcc 2.8 or egcs. (This adds
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)

Merge arch/sun3x into arch/sun3

branches: 1.66.2;
Make sure CPP, AR, AS, and RANLIB are defined.

Define LORDER, NM, and TSORT here, like we do the rest of the tools.

Generate assym.h into assym.h.tmp first, then move it. (safety)
Add a dependency for stub.o:Makefile

branches: 1.63.2;
use common genassym.awk

define SIZE?=size, and use ${SIZE} instead of size. makes cross
compilation easier

PR/4162: Chris Jones: make cleandir does not work properly; it does not
remove the object files and the .depend file in the kernel build directory.

Kill vestiges of Locore.c.

branches: 1.59.4;
Fixup dependencies

Add -fno-defer-pop to COPTS (helps ddb backtrace).
Add AFLAGS=-m68020 and use it with ${AS} commands.
Depend kgdb_stub.o on Makefile (KGDBDEV, KGDBRATE).

Get rid of HOSTED_CC.

branches: 1.56.2;
change :: to :

Nuke some options GENERIC residue.

Nuke some GENERIC residue.

Make this compile with -Werror -Wall -Wstrict-prototypes
(finally! yea!) Also get rid of __BROKEN_INDIRECT_CONFIG

* Replace explicit -O2 in CFLAGS with COPTS macro. Default COPTS?= -O2.
Lets users over-ride with makeoptions COPTS="..." in kernel config files.

Leave `mandatory' flags (like -msoft-float which on m68k enforces no
FP in kernel) in CFLAGS.

Move strip(1) flags into a separate variable, so that $STRIP can
be passed to subordinate make(1)s. Remove $TOUCH. Add HOSTED_CC,
HOSTED_CPPFLAGS, and HOSTED_CFLAGS, and use them when depending genassym.

Wrap the default definition of `S' in `.ifndef'.

Put into . Remove hooks for `config-dependent' and
`device-driver' flags.

* Add a HOSTED_C_C variable, which strips `-p', `-pg', and
`-nostdinc', and use it when building genassym.
* Use `-nostdinc' just to be sure we're self-contained.

* Define CWARNFLAGS and MKDEP in some moderately consistent fashion.
* Make S expand to an absolute path at compile time.
* Use `-S' rather than `-x' to remove debugging symbols.
* Garbage collect unused variables.
* Reverse a handful of port-specific changes that do not correspond to
the common build model and are not needed.

Take control over the kernel libraries so cross-build is easier.

Several minor changes to make cross-compilation easier.
(I do most compiles on a sparc these days...)

Make `make depend' work for libraries.

Do not build vnode_if.[ch] for each kernel. Build them once, like the
various syscall sources/headers, and just compile them. From PR 2142, OK'd
by mycroft.

Define build programs with `?=', so they can be overridden with `makeoptions'.

keep static symbols

Fix mkdep problems due to missing flags.

Use `-traditional-cpp' when building .s and .S files.

Clone these, and fix many bugs.

assym.s -> assym.h
(Some ports did this already.)

LOCORE -> _LOCORE

Switch to ncr_si (will just do PIO for now) and cleanup

branches: 1.34.2;
Compile the kernel with -Werror -fno-builtin.

Add ${LIBKERN} ${LIBCOMPAT} to SYSTEM_DEP so they are built.
Move ${DEBUG} from ${CC} to ${CFLAGS} for compatibility.

Makefile.`arch`: - Add -lcompat
- Change clean: target to be a double dep one,
so libraries can use the clean target too
- Add genassym to the clean targets

Retool for native build.

Merged locore code back into locore.s

Removing -DKERNEL, transition to _KERNEL has been completed

Added -D_KERNEL to CFLAGS alongside each -DKERNEL.

Minor tweaks: avoid accidental FPU instructions,
allow DEBUG=-O override on the make command line.

Include vnode_if.c in mkdep args.

Cleanup (cpp flags just once)

Lots of changes. Fairly stable now.

new RCS ID format.

Turn on optimization.

Add mising dependency

branches: 1.20.2;
Move vnode_if.o earlier in the OBJ list.

Update for new FS code (vnode_if.*)

SCSI driver works!

Make conf.o depend on the Makefile

fixed to use new queue stuff. random diffs to make ddb stuff mostly compile

cleanup

boots, presents shell prompt, and doesn't crash immediately

sun3 port works under NetBSD-current now. rcsids probably fucked

Now works with current tree, as opposed to the july 8th tree in which it was
written.
Requires magnum infrastructure now, particularly the clock stuff.
Fails to exec init because the /sbin/init binary
is a sunos binary. Next step is to integrate sunos compatibility code
from /sys/compat/sunos, and the amiga port.
Does not yet implement MACHINE_NOCONTIG support.

[from glass Mon Nov 22 21:22:45 PST 1993 home tag: home2]

some cleanup, better than sending adam reminder notes

sun3 port updated. netboot integrated.

snapshot. for uploading. gets lost in swtch after enablertclock()

cute bug that mycroft fixed in the hp300 stuff

runs up to and including configure().
todo: exceptions, interrupt support, make isrs affect vector table
kernel/user stacks

make config -g work, add timesink config

gets to consinit() and blows up

it links with out any unresolved symbols, last few are just stubs
because we aren't likely to get near execing init for a while

Fri Jul 30 16:52:00 PDT 1993:
snapshot. things compile but don't link. pmap stuff compiles but
just starting work on interfacing it to the vm system. current projects
appear to be both physical memory and virtual memory maps.

use gas; add support for more stuff

initial commit. little of this actually works
