copy down changes from libc

Alpha support from libc.

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.

- remove bcmp(9), bcopy(9), and bzero(9) from libkern since <sys/systm.h> has
macro which replace them with mem*() functions in #ifdef _KERNEL as noted
in man pages
- move declarations of bcopy(3) and bzero(3) into <lib/libsa/stand.h>
since they are still in libsa for some MD standalone sources
(I guess all bcmp(3) in standalone sources have been replaced with memcmp(3)
but they should be replaced with memcmp() anyway)

Use ${TOOL_M4} instead of "m4". (I only tested this fix

Move the bswap functions from libutil to libc (this bups the

merge the bnswap() assembly versions with nto* and hton* using symbols

namespace pollution.

Sync libkern with libc.

add memcmp.c memmove.S

Use the assembler version of memcpy().

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: 1.10.8;
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).

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.)

fix up for new libkern path specs

add an assembly version of ffs(), copied down from libc

locc() is unused. Remove it from the machine-independent kernel interface.

files copied from libc

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.)

This is a port of the OpenBSD pmap and trap handling code to get us

- Performance boost on some/all machines.
- Well on the way to PA2.0 (in 32bit mode) support. Several
machines probe hardware, but fail sometime after interrupts
are enabled.

Other things changed / fixed on the branch are

- update autoconf to use the OpenBSD code.
- com @ dino is very close to being supported.
- HPPA_REDZONE has been replaced with a working redzone which
is enabled with DIAGNOSTIC.
- UPAGES has been halved in size.
- power(4) from OpenBSD to fix a few bugs.
- updated list of modules from OpenBSD.
- initial ports of uturn(4), astro(4) and elroy(4).
- update some copyrights (remove advertising clause, etc.)

Thanks to mjf for some of the above, testing and listening.

Extends the Opencrypto API to allow the destination buffer size to be
specified when its not the same size as the input buffer (i.e. for
operations like compress and decompress).
The crypto_op and crypt_n_op structures gain a u_int dst_len field.
The session_op structure gains a comp_alg field to specify a compression
algorithm.
Moved four ioctls to new ids; CIOCGSESSION, CIOCNGSESSION, CIOCCRYPT,
and CIOCNCRYPTM.
Added four backward compatible ioctls; OCIOCGSESSION, OCIOCNGSESSION,
OCIOCCRYPT, and OCIOCNCRYPTM.

Backward compatibility is maintained in ocryptodev.h and ocryptodev.c which
implement the original ioctls and set dst_len and comp_alg to 0.

Adds user-space access to compression features.

Adds software gzip support (CRYPTO_GZIP_COMP).

Adds the fast version of crc32 from zlib to libkern. This should be generally
useful and provide a place to start normalizing the various crc32 routines
in the kernel. The crc32 routine is used in this patch to support GZIP.

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: 1.13.8;
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).

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.)

locc() is unused. Remove it from the machine-independent kernel interface.

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.)

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.

Rename jump label to something a little more negative. No, I'm
not doing it for cosmetic value or out of angst. See, PIC_PROLOGUE
on i386 uses the "1" label internally. Now, everything would be
fine and dandy for the first 551245 calls to random. After that
p+q is negative and the jump is taken. However, it is taken into
the middle of PIC_PROLOGUE instead of where upon superficial
examination we assumed we are jumping. This causes wrong(tm) things
to happen and "ret" triggers a jump into hyperspace.

Did a ``make copy-to-libkern'' from libc to copy libc files to libkern.
Checking them in to make people happy.

Use common sources with userland.

merge ktrace-lwp.

netbsd.org -> NetBSD.org

This was the last commit of this kind to src/sys, which is now totally
"NetBSD.org clean". Thanks for the patiance, and sorry for all the commits.

rindex() shouldn't be used in the kernel. Use strrchr() instead.

branches: 1.1.48;
Add these as well.

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.

Fix little bit, and add a few files.
current status is to see following thread.

Sync w/ libc.

branches: 1.3.14; 1.3.16; 1.3.20;
Sync with libc, and add random.S.

new RCS ID format.

copied over so lib/libc/arch not needed to build kernel.

Add m68k assembler version of __muldi3().

This is intended for 68060:
- GCC does not emit __muldi3() for 68020-40, that have 32 * 32 --> 64 mulul
- mulsl (and moveml), used in this code, are not implemented for 68010

In comparison with that from compiler_rt, this version saves:
- 12% of processing time
- 12 bytes of stack
- 50 bytes of code size
Also, slightly faster, memory saving, and smaller than libgcc version.

By examining with evcnt(9), __muldi3() is invoked more than 1000 times per
sec by kernel, which should justify to introduce assembler version of this
function.

Revert untested and unnecessary change in previous rev 1.36.

Our autobuild doesn't always reflect the latest fixes.

add mulsi3, needed by inet_addr.o

branches: 1.35.2;
Revert 1.33 and 1.34 for now, until either .INVISIBLE is reinstanciated
or random.S dropped.

Make random.S invisible for coldfire too (e.g. anything not "m68k")

use .INVISIBLE to hide random.S, instead of extra rules.

Merge riastradh-drm2 to HEAD.

Reorder a little to make clearer.

Remove some .c files accidentally left on the .S lines

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

- remove bcmp(9), bcopy(9), and bzero(9) from libkern since <sys/systm.h> has
macro which replace them with mem*() functions in #ifdef _KERNEL as noted
in man pages
- move declarations of bcopy(3) and bzero(3) into <lib/libsa/stand.h>
since they are still in libsa for some MD standalone sources
(I guess all bcmp(3) in standalone sources have been replaced with memcmp(3)
but they should be replaced with memcmp() anyway)

Don't try to build random.S on 68010.

branches: 1.24.6;
add strtoul.c, it's now used in MI code.

Added brand-new integer multiply and divide support, used only
on the m68000.

On the m68000, if and only if gcc doesn't seem to know
where libgcc.a is, fall back to one under DESTDIR.

branches: 1.21.2;
When MACHINE_ARCH is m68000, compile ffs.c and random.c
instead of ffs.s and random.s, and sneak the libgcc
integer support routines into the list of library objects.

Add a strcasecmp(), modified from chopps's strncasecmp().

branches: 1.19.12;
add memcmp.S memmove.S

Use the new .S files.

Sync with libc, and add random.S.

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

Implement assembly byte-swap functions.

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: 1.12.8;
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).
