sync with libc source: remove DEFS.h

new RCS ID format.

auto-copied from libc

Revert previous. christos fixed the root cause.

Make sparc64 32-bit kernel buildable.

Move that majority of the 'SRCS+= foo.c' into the main Makefile.libkern.
Any .S files added by the arch/*/Makefile.inc cause the .c file to
be excluded.
Specific exclusions added using NO_SRCS to match previous files.
At least sparc, sparc64, i386, amd64 and vax GENERIC still build.
(There is a fubar with the naming of the byte-swap files ...)

Split the lines that add .c to SRCS from those that add .S
No changes (apart from the order) intended.

branches: 1.32.74;
merge ktrace-lwp.

Use ${TOOL_M4} instead of "m4". (I only tested this fix
for sparc but not sparc64 or alpha yet.)

Noticed problem when building NetBSD/sparc from a Linux/i386 host
that didn't have "m4".

branches: 1.30.8;
Add '.SUFFIXES: .m4' here, now that <sys.mk> doesn't provide it anymore.
It appears that .PATH.m4: needs it.
Should fix problem noted in private mail by Markus W Kilbinger.

don't need bcmp() and bzero()

branches: 1.28.10;
Add strtoul.c, otherwise kernels using "wi* at pcmcia?" do not work
anymore.

Why only four archs provide this is beyound me.

branches: 1.27.2;
Sync with libc: use bzero-based assembly version of memset().

branches: 1.26.2;
Add a strcasecmp(), modified from chopps's strncasecmp().

branches: 1.25.2;
Add .PATH.m4

branches: 1.24.4;
don't list any *.S files in SRCS multiple times, once is enough.

branches: 1.23.2;
add memcmp.c

Move random() from kernel.

Don't list bcopy.c here, since we only want memcpy() and not bcopy().
XXX What a kluge!

We need memcpy().

Add some missing things.

add rules like those in libc to build strchr() and strrchr() (the latter
is being added to libkern by this commit). remove strchr.c from
archs' Makefile.inc files to go along with this. (If an arch has
a .S version, it should be copied down and added to the apropriate
Makefile.inc.)

add memchr() to libkern

Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern.
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.

branches: 1.15.8;
add strchr() to libkern. strchr.c copied from libc's "index.c", but with
appropriate definitions so that it'll build strchr(), and so that it builds
correctly in libkern (needed to #define NULL).

Remove `chmod 444's.

Add machine-independent assertion-checking support. macros are:

assert() which always does assertion checking
unless "NDEBUG" is defined.

KASSERT() which does assertion checking if DIAGNOSTIC
is defined.

KDASSERT() which does assertion checking if DEBUG is
define. This macro exists for compatibility
with existing ports' assertion checking macros.
(Assertion checking is not typically an
"expensive" operation, and DIAGNOSTIC should be
used for inexpensive consistency checks.)

Remove memset.c; it is not currently used, and .c files should belong in
the MI portion of libkern. When/if we move to use mem* routines in the kernel
we can add it to the MI portion/write a memset.s.

add strncasecmp.c to ports' libkern Makefile.inc's. When adding a new
source file to libkern, it should be added to _ALL_ ports makefiles if
it is machine-independent and used by machine-independent code (in
this case adosfs). (There are several arguments that say that
strncasecmp should not be in libkern at all, and i think they're
good ones, but as long as ADOSFS needs it to link, it has to be here
for all architectures.)

Remove setjmp() and ffs().

G/c this stale copy of SYS.h. It has not been updated since 1999. It
has not been used since an unused copy of setjmp.S has been removed
from here in 2002 (i386 removed its own in 1999).

Remove memset.c; it is not currently used, and .c files should belong in

we can add it to the MI portion/write a memset.s.

don't include user-land headers in libkern files when compiling for
the kernel. memset.c does not belong here. it either belongs in
the MI libkern directory, or does not belong in libkern at all.

Back out previous change.

Provide a memset() for the i386 (assembly version), and move memset.c
out into the libkern proper in case other ports want to use it.
i386 kernels with COMPAT_LINUX should compile now.
