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.

distclean is a synonym for cleandir

FP in kernel) in CFLAGS.

Set CWARNFLAGS to:
-Werror -Wall -Wstrict-prototypes -Wmissing-prototypes
-Wcast-qual -Wno-format
(if not already set). -Wno-format is necessary because of the few
bits of code in the tree that use NetBSD's special kernel printf()
formats, and because there are a few bits of code that try to use the 'q'
modifier to print int64_t's (but int64_t's are only 'long' on the
alpha, not 'long long').

compile .S files with cpp | sed | as, to work around a bug with the

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.

Abstract out a large chunk of the kernel build machinery so that new
build features (such as ross's DEBUGLIST) can easily be applied to all
ports. This should reduce the complexity of each port's kernel
Makefile considerably. Line counts:

Roll i386, alpha, sparc, and vax over to the new build machinery.

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.

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. :)

Be less drastic when running strip(1) on DEBUG=-g kernels.

Fix bug exposed by new "mkdep" program:
"${SFILES}" is empty so that "cc" will fail with "No input files"
during "mkdep".

Some minor, mostly costmetic, changes to CPPFLAGS/CFLAGS.

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

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.)

1. Always link at the high address, now that we can use free ram below
the kernel on most platforms, including all of the entry-level platforms.
2. Kill the comments and options for load address selection.

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

branches: 1.27.2;
* 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.

Set CWARNFLAGS to:
-Werror -Wall -Wstrict-prototypes -Wmissing-prototypes
-Wcast-qual -Wno-format
(if not already set). -Wno-format is necessary because of the few
bits of code in the tree that use NetBSD's special kernel printf()
formats, and because there are a few bits of code that try to use the 'q'
modifier to print int64_t's (but int64_t's are only 'long' on the
alpha, not 'long long').

compile .S files with cpp | sed | as, to work around a bug with the
ELF-outputting version of the assembler. (It was dying when it saw
some CPP line number markers.) This is temporary. (Workaround suggested
by Matt Thomas.)

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'.

kill 'microcode' Makefile.inc include, define CWARNFLAGS with ?=.

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.

include 'microcode' dependencies, in case the aic7xxx driver is ever made
to work on 64-bit systems or in case other drivers need it eventually.

add -Werror -Wall -Wstrict-prototypes -Wmissing-prototypes as
CWARNFLAGS in the Makefile, but (for the time being, i.e. until that
works) override that with 'makeoptions' in std.alpha.

add -O2 to the optimization flags. A reason why optimization seemed
to fail on some systems was never found; hopefully it's gone away (or
was never really there).

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'.

Fix mkdep problems due to missing flags.

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

Clone these, and fix many bugs.

preliminary Alpha support. note that NOT ALL OF THE MODIFICATIONS TO
THE REST OF THE KERNEL ARE IN THE TREE YET. Also, some of this is
_incredibly_ hack-ish, etc., but it works.

- 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.

build features (such as ross's DEBUGLIST) can easily be applied to all
ports. This should reduce the complexity of each port's kernel
Makefile considerably. Line counts:

227 arch/i386/conf/Makefile.i386.orig
98 arch/i386/conf/Makefile.i386
227 arch/alpha/conf/Makefile.alpha.orig
99 arch/alpha/conf/Makefile.alpha
219 arch/sparc/conf/Makefile.sparc.orig
102 arch/sparc/conf/Makefile.sparc
215 arch/vax/conf/Makefile.vax.orig
102 arch/vax/conf/Makefile.vax
253 conf/Makefile.kern.inc

Roll i386, alpha, sparc, and vax over to the new build machinery.

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: 1.66.2;
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: 1.65.2; 1.65.4;
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.

Fix new DEBUGLIST feature.

Add DEBUGLIST mechanism. Example config line:
makeoptions DEBUGLIST="uvm* trap ufs*"
This turns on -g for only those files matching a DEBUGLIST pattern word.

branches: 1.62.2;
delete obsolete comment

generate dependencies for assym.h for make depend, fix dependency
for maxusers (make assym.h depend on Makefile)

remove rules for genassym.c, it's no longer pertinent

convert to use common genassym.cf

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

branches: 1.53.2;
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. :)

Be less drastic when running strip(1) on DEBUG=-g kernels.

Fix generation of locore.s dependencies.

branches: 1.49.2; 1.49.4; 1.49.6;
Do all the fancy printf format checking.

Fix bug exposed by new "mkdep" program:
"${SFILES}" is empty so that "cc" will fail with "No input files"
during "mkdep".

Some minor, mostly costmetic, changes to CPPFLAGS/CFLAGS.

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

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.)

1. Always link at the high address, now that we can use free ram below
the kernel on most platforms, including all of the entry-level platforms.
2. Kill the comments and options for load address selection.
3. Kill the default -g.

Make sure CPP, AR, AS, and RANLIB are defined.

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

--Add handcrafted stack frame directives to locore.s palcode vector
--entries / remove kernel entry from locore / reorganize vector entry
--code. Enables access to stack frames transitively w.r.t. palcode
--vectors, e.g. upward traceback works, inverting (possibly several)
--kernel vectors. Until now, all trackbacks ended at the first-reached
--instance of trap(), which was totally useless as there is no mystery
--to trap->panic->cpu_reboot

branches: 1.37.2;
use common genassym.awk

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.

lie to the compiler when doing mkdep so that it depends .s files correctly.

branches: 1.34.2;
* move COPTS out of the 'program variables' section of the makefile and
into the 'argument variables' section.
* define variables for CPP and SIZE, defaulting to cpp and size, respectively.
* kill HOSTED_C*, since it's no longer used.
* use ${SIZE} rather than using 'size' directly, so it can be overridden for
cross-builds.
* generate assym.h via assym.s and an awk script.

clean up NetBSD RCS ID strings

Nuke some options GENERIC residue.

Nuke some GENERIC residue.

update for new kernel library Makefile.inc rules

make load address settable via LOADADDRESS make option

branches: 1.28.2;
for now, -Wcast-qual is just not practical in the kernel

branches: 1.27.2;
* 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.

Set CWARNFLAGS to:
-Werror -Wall -Wstrict-prototypes -Wmissing-prototypes
-Wcast-qual -Wno-format
(if not already set). -Wno-format is necessary because of the few
bits of code in the tree that use NetBSD's special kernel printf()
formats, and because there are a few bits of code that try to use the 'q'
modifier to print int64_t's (but int64_t's are only 'long' on the
alpha, not 'long long').

compile .S files with cpp | sed | as, to work around a bug with the
ELF-outputting version of the assembler. (It was dying when it saw
some CPP line number markers.) This is temporary. (Workaround suggested
by Matt Thomas.)

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'.

kill 'microcode' Makefile.inc include, define CWARNFLAGS with ?=.

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.

include 'microcode' dependencies, in case the aic7xxx driver is ever made
to work on 64-bit systems or in case other drivers need it eventually.

add -Werror -Wall -Wstrict-prototypes -Wmissing-prototypes as
CWARNFLAGS in the Makefile, but (for the time being, i.e. until that
works) override that with 'makeoptions' in std.alpha.

add -O2 to the optimization flags. A reason why optimization seemed
to fail on some systems was never found; hopefully it's gone away (or
was never really there).

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'.

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.)

wholesale update from my NetBSD/Alpha source tree. Includes:
Support for AXPpci CPUs,
Support for AlphaStation 600 CPUs,
new boot block structure, which requires an 'installboot'
program and works a lot like the NetBSD/sparc boot blocks.

Compile the kernel with -fno-builtin.

update for all the latest bells and whistles

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

Removing -DKERNEL, transition to _KERNEL has been completed

kill some non-gnu-tools cruft, allow rest of programs to be parameterized

Added -D_KERNEL to CFLAGS alongside each -DKERNEL.

preliminary Alpha support. note that NOT ALL OF THE MODIFICATIONS TO
THE REST OF THE KERNEL ARE IN THE TREE YET. Also, some of this is
_incredibly_ hack-ish, etc., but it works.
