Use the standard build rules.

branches: 1.100.16;
remove a bunch of "@echo done" from the tail of rules. these messages
were vaguely useful back when we didn't run make -j, but now you end
up with a single line "done" every so often, with no idea what it is
for. very few other targets claim they're done so just remove these.

Order library object build.

Sprinkle more done messages.

branches: 1.97.6;
Revert previous revision. It bkeaks profiling kernel builds.
LIBISPRIVATE unconditionnally set MKPROFILE to no, preventing
profiling kernel library.

Simplify by using LIBISPRIVATE?= yes

branches: 1.95.24; 1.95.28;
Change the use of formally undocumented features, which have now been
made to fail. Specifically, change
.ifdef(SYMBOL) -> .ifdef SYMBOL or .if defined(SYMBOL),
and corresponding for .ifndef.

Also correct one error in lib/libm/Makefile (.ifdef (${MKCOMPLEX} != "no")?!?).

Split variables out of Makefile into Makefile.libkern so that we
can easily just .include it for the proper SRCS etc. definitions
in case we're interested in the files but not in building an actual
libkern.{a,o}. for librump

replace bitmask_snprintf(9) with snprintb(3)

Add new ptree (Patricia / RADIX tree) implementation to NetBSD.

Our qsort() is inappropriate for kernel use because it makes recursive
calls. Replace it with a kheapsort() function in kernel. Pointed out
by tron@.

Make qsort() available in libkern.

branches: 1.89.2; 1.89.4; 1.89.6; 1.89.10;
Move rb.c from sys/lib/libkern to common so it can be in both libc and libkern.

Include cpuset.

Add strsep(3) to libkern.

To avoid code duplication, move strsep.c to the kernel/userland
common files.

Soon I will commit source-address selection (options IPSELSRC).
It will use strsep(3).

Merge kernel and userland rmd160 and sha2 implementation.
XXX: We still install rmd160.h and sha2.h in /usr/include/crypto, unlike
the other hash functions which get installed in /usr/include for compatibility.

- Move strtoll.c and strtoull.c from libc/stdlib to common/libc/stdlib.
- Add strtoll.c and strtoull.c to libkern.

branches: 1.81.2; 1.81.4;
Add src/common/include to include header search path so that
standalone programs can be built without installed ${DESTDIR} tree.
Okayed by christos, and should close PR 33431.

Support for building proplib in the kernel.

Move strtoumax.c from libc/stdlib to common/libc/stdlib and include it
in libkern. Required for new code coming soon.

branches: 1.78.2;
Provide BCD<->binary conversion in libkern and turn <dev/clock_subr.h>'s
FROMBCD()/TOBCD() macros into wrappers around it, resulting in both
smaller code footprint and elimination of possible issues due to
multiple evaluation of macro arguments.

Suggested by Simon Burge and Anders Gavare on tech-kern.

branches: 1.77.4; 1.77.6; 1.77.8; 1.77.10;
Use common sources with userland.

merge ktrace-lwp.

put mcount.c in the normal object list, so that "make depend" works.
use a gcc attribute to prevent it from being instrumented.

Redo previous; don't add mcount.po to POBJS when MKPROFILE=no.

Create mcount.po only when MKPROFILE != no.

branches: 1.72.4;
nuke trailing whitespace

branches: 1.71.8; 1.71.10;
Add xlat_mbr_fstype - converts mbr type to disklabel type

branches: 1.70.2;
add strl{cpy,cat} to libkern. code from lib/libc/string (originally from openbsd).

If LIBKERN_ARCH is defined, use that as the architecture-specific
subdirectory. Needed for the x86_64 32bit compile case.

set LLIBS= so we don't try to check the lint lib against llib-lc.ln

Unconditionally add strstr.c. Bill Studenmund.

Add strstr() to libkern. For now, it's only used in i386 (for processor
identification).

Updated version of cscope/mkid support. Check libkern and compat lib
for source files. Also include header files in mkid run.

have arc4random(9).

branches: 1.63.8; 1.63.10;
MKfoo=no -> NOfoo

Undefine DESTDIR; we don't want the special DESTDIR <bsd.lib.mk>
handling for kernel libraries.

XXX this build method should be replaced by something more sane

Move _insque()/_remque() to libkern. Once remaining uses would
be converted to <sys/queue.h> macros, _insque()/_remque() would be eliminated
altogether.

branches: 1.60.2; 1.60.4;
Don't set ARCHSUBDIR to empty string.

Use MACHINE_CPU to find the architecture subdir, or MACHINE_ARCH if that
exists. Same algorithm as libc uses.

Use arm arch directory for arm32 as well as arm26.

prepare for sh3e[bl] split

Create a shared set of ARM sources for libkern and move arm26 over to using
them.

These are identical to the current arm32 sources with the following exceptions:
- References to C labels are wrapped in _C_LABEL().
- Function returns have an alternate version inside #ifdef __APCS_26__.

add md4c.c

make CMSG_ALIGN always synchronize with kernel's idea of ALIGNBYTES.
ancillary data alignment will be ALIGNBYTES, not sizeof(long) - 1, from now.

CMSG_xx will NOT resolve into constant. if you use CMSG_xx to allocate
arrays, you'll lose.

bump shlib minor for libc.

NOTE: if you are on top of arch with ALIGNBYTES != sizeof(long) - 1,
you need to recompile IPv6-related binaries. there is no way to guarantee
backward compat in this aspect. sorry for this. this should be the last
backward compat breakage for IPv6-related ancillary data manipulation.
(we still have PR 9516 for unix-domain sockets...)

branches: 1.53.2;
move intoa() from libsa:net.c to libkern, turn inet_ntoa() into a macro,
nuke ip_convertaddr()

Build libraries for kernel/standalone code from within their compilation
directories and use .PATH to lookup the source files.
(Formerly, the libs were built from the source dirs, with MAKEOBJDIR
set to the compilation directory.)
This solves 2 problems:
-"mkdep" and "make" are now consistent about the file lookup, this fixes
bad interactions with amd reported in PR bin/7374 (Arne Juul) and
lossage reported by Andrew Gillham ("obj" dirs and relative paths still
don't work well together)
-kernel compile trees can be moved around without forcing a new
"make depend" - fixing PR kern/4021 by Martin Husemann

Add inet_addr.c (for nfs_bootparam.c)

branches: 1.50.4;
make the mipse[lb]->mips translation really work
(the S/// doesn't work as I'm now telling the 3rd time),
put the translation onto a separate line to make it more understandable

Makefile ${MACHINE_ARCH} changes for mips{eb,el}, as suggested by
Izumi Tsutsui <tsutsui@ceres.dti.ne.jp>

no need to add ${OBJS} to POBJS here, bsd.lib.mk does it automatically.

convert from NOxxx= to MKxxx=no.
include <bsd.own.mk> if testing a MKxxx variable.

replace several special targets with stub .c files, as in libc/string

fix silly comment typo

make libkern build memmove() properly

branches: 1.43.2;
Make the combination "profiled kernel" and "${KERN_AS} == "library""
work too. (mcount.po was forgotten)

Add a small string pattern matching function to facilitate pcmcia cis string
matches.

add sha1.c, and build it.

Build memcpy() out of bcopy() by default.

update to match (now-fixed) libc rules for strchr and strrchr.
Brokenness pointed out by Matthias Drochner.

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.)

Use LORDER, TSORT

branches: 1.36.8;
Back out BUILDDIR and NOINSTALL changes.

Use new NOINSTALL option for libraries that are used only during the build
of a program, and not installed into the final system.

Use libinstall::, not install:, to prevent instaling LIB.

Build md5c.c

allow includers to specify library-specific CPP flags via ${LIB}MISCCPPFLAGS

branches: 1.31.6;
Add anchors so that only exactly `-I. is modified.

Convert the -I. to -I${.OBJDIR}, so that the `machine symlink is available.

We dont need to pass down COMPATDIR and KERNDIR.

Run the child make in the source directory, so that nothing here needs to be
changed when the compile directory is outside the source tree.

Make sure we clean up libkern.o and libkern.po, too. Closes PRs 1951
and 2387.

don't get rid of the -D_KERNEL in KERNCPPFLAGS

Simplify, and add support for passing CPPFLAGS.

set, don't add to, CFLAGS from KERNCFLAGS. Do assignment of CC and
CFLAGS earlier, so that the arch-specific Makefile can add to them.

Build libkern as one .o file, so that all symbols defined therein are
always available to loadable modules.

Remove old .PATH directives that referenced libc source.
Libkern has its own copies of all the requisite source files.

Add the ability to override KERNREL and KERNDST.

Build libkern in the kernel compilation directory, like libcompat.

slight cleanup/reorg. don't use quad code on the alpha.

Change a dependency to work when not using `all' target.
