Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.

Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

Add libc glue for libtre.
tre will be compiled without approx and wchar/mulibyte support to

This needs a lot of testing.

Only enabled when USE_LIBTRE is set to `yes'.

1. fix build problem CITRUS=no
2. make CITRUS={yes,no} knob friendly with libc/compat.

Add the constant database reader (cdbr(3)) and writer ((cdbw(3)).
They implement a space efficent write-once database with fast access
path. Switch the services(5) database to use cdb. The size of the
database file decreases from 2.1MB disk space to 307KB. Access
performance is about the same if setservent(0) is used and about an
order of magnitude faster otherwise. services_mkdb defaults to the new
format, but can optionally create the old db(3) format as well for
statically linked legacy applications.

Provide the phony "tags" target as previous. Make it depend on the real
target. In case someone assumes the target as an interface.

Make the local "tags" target an absolute path, ${.OBJDIR}/tags, otherwise
it conflicts with the "tags" target defined in bsd.own.mk, which is .PHONY,
which causes you to re-build "tags" everytime you re-run make.

Change (slightly) the way NO_SRCS is processed, update big comment!
Now the .c file is removed from SRCS for both .S and .c in NO_SRSC.
The .c file is added to LSRCS for .S files in NO_SRCS.
(.S files in SRCS have the same treatment - but also get compiled.)
Allows vax build to be fixed.
Also the previous version failed to add to LSRCS correctly.

If SRCS contains any .S files then remove the corresponding .c file from
SRCS and add to LSRCS (for lint).
Change the 'string' Makefiles so that the arch/*/string/Makefile.inc
need only specify the .S files for that architecture and not the .c
files for all the files they don't override.

TOOL_CONFIG TOOL_CRUNCHGEN TOOL_CTAGS TOOL_DB TOOL_EQN TOOL_FGEN
TOOL_GENCAT TOOL_GROFF TOOL_HEXDUMP TOOL_INDXBIB TOOL_INSTALLBOOT

TOOL_FOO?= foo
and for the ${USETOOLS}=="yes" case in <bsd.own.mk>, provide override:

Document all of these in bsd.README.

This cleans up a chunk of potential (and actual) namespace collision
within our build infrastructure, as well as improves consistency in
the share/mk documentation and provision of appropriate defaults for
each of these variables.

refine i18n stuffs.
- add libc/citrus directory.
this directory contains the common stuffs not only for locale
but also other facilities relating to i18n (e.g. iconv).
- To keep the binary compatibility for the ctype modules easily,
the interface between libc and the modules is simplified.
- For the future integrated extension, module pool is renamed
from "/usr/lib/runemodule" to "/usr/lib/i18n".
In the future, this directory will contain the modules for "iconv",
"collation", etc.
- some cosmetic changes.
- Bug fix for runetype.h; __attribute__((__packed__)) is placed at
the wrong position and it is invalid unintentionally.
But, the all members of the structures seem well-aligned. Thus,
this bug causes no problem, hopefully.

HEADS UP:
- /usr/lib/rumemodule is obsoleted. If you use the multibyte locales,
you need to install /usr/lib/i18n/* from sys/lib/i18n_module .
- The binary compatibility of /usr/share/locale/*/LC_CTYPE is probably kept.
Perhaps, the bug fix about __packed__ mentioned above breaks the
compatibility... Be careful especially on 64bit platforms.

No need to reference .OBJDIR here.

Make it possible for ctags to be a host tool.

* Add user-controlled mk.conf variables
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".

- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.

- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs

* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz

* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.

* Always install /sbin/init statically (for now)


The net effect of these changes depends on how the variables are set:

1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so

2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so

3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed

Create shared ARM source for libc, and move arm26 port over to using it.
The code is (almost) a direct copy of the current arm26 sources.
It's identical to the current arm32 sources, with the following exceptions:
- _C_LABEL is used on references to C labels from assembler.
- Function returns in assembler have APCS-26 versions in #ifdef __APCS_26__.
- It uses SoftFloat 2a rather than SoftFloat 1a.

The first two of these should be inconsequential. I believe that SoftFloat 2a
should work on arm32 and be backward-compatible with existing code, but this
is not obviously true. For now, arm32 remains using its own bits of libc.

Ignore empty translation unit errors.

Provide the phony "tags" target as previous. Make it depend on the real

Make the local "tags" target an absolute path, ${.OBJDIR}/tags, otherwise

which causes you to re-build "tags" everytime you re-run make.

Change (slightly) the way NO_SRCS is processed, update big comment!
Now the .c file is removed from SRCS for both .S and .c in NO_SRSC.
The .c file is added to LSRCS for .S files in NO_SRCS.
(.S files in SRCS have the same treatment - but also get compiled.)
Allows vax build to be fixed.
Also the previous version failed to add to LSRCS correctly.

If SRCS contains any .S files then remove the corresponding .c file from
SRCS and add to LSRCS (for lint).
Change the 'string' Makefiles so that the arch/*/string/Makefile.inc
need only specify the .S files for that architecture and not the .c
files for all the files they don't override.

refine i18n stuffs.
- add libc/citrus directory.
this directory contains the common stuffs not only for locale
but also other facilities relating to i18n (e.g. iconv).
- To keep the binary compatibility for the ctype modules easily,
the interface between libc and the modules is simplified.
- For the future integrated extension, module pool is renamed
from "/usr/lib/runemodule" to "/usr/lib/i18n".
In the future, this directory will contain the modules for "iconv",
"collation", etc.
- some cosmetic changes.
- Bug fix for runetype.h; __attribute__((__packed__)) is placed at
the wrong position and it is invalid unintentionally.
But, the all members of the structures seem well-aligned. Thus,
this bug causes no problem, hopefully.

HEADS UP:
- /usr/lib/rumemodule is obsoleted. If you use the multibyte locales,
you need to install /usr/lib/i18n/* from sys/lib/i18n_module .
- The binary compatibility of /usr/share/locale/*/LC_CTYPE is probably kept.
Perhaps, the bug fix about __packed__ mentioned above breaks the
compatibility... Be careful especially on 64bit platforms.

No need to reference .OBJDIR here.

Make it possible for ctags to be a host tool.

* Add user-controlled mk.conf variables
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".

- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.

- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs

* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz

* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.

* Always install /sbin/init statically (for now)


The net effect of these changes depends on how the variables are set:

1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so

2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so

3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed

Create shared ARM source for libc, and move arm26 port over to using it.
The code is (almost) a direct copy of the current arm26 sources.
It's identical to the current arm32 sources, with the following exceptions:
- _C_LABEL is used on references to C labels from assembler.
- Function returns in assembler have APCS-26 versions in #ifdef __APCS_26__.
- It uses SoftFloat 2a rather than SoftFloat 1a.

The first two of these should be inconsequential. I believe that SoftFloat 2a
should work on arm32 and be backward-compatible with existing code, but this
is not obviously true. For now, arm32 remains using its own bits of libc.

Ignore empty translation unit errors.

Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is

Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.

Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.

This material is based upon work partially supported by

It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

and for the ${USETOOLS}=="yes" case in <bsd.own.mk>, provide override:
TOOL_FOO= ${TOOLDIR}/bin/${_TOOL_PREFIX}foo

Document all of these in bsd.README.

This cleans up a chunk of potential (and actual) namespace collision
within our build infrastructure, as well as improves consistency in
the share/mk documentation and provision of appropriate defaults for
each of these variables.

Citrus iconv support(4)
add iconv external I/F (iconv.h - iconv_open()/iconv()/iconv_close()) and
iconv(1) utility.
TODO:
- bump libc minor.
- add iconv data files.
- create manpages: iconv_open(3)/iconv(3)/iconv_close(3)/iconv(1)/
mkesdb(1)/mkcsmapper(1).

Add slovak language libc message catalog.

Add a Catalan libc message catalog file (plus everything else needed to
track the file). Closes my own PR lib/19498.

Merge the nathanw_sa branch.

Explicitly move setting of NOxxx and USE_SHLIBDIR to the top of the
Makefile (before including <bsd.own.mk>)

Use ${NETBSDSRCDIR}/some/path instead of ${.CURDIR}/../../some/path (etc).
(Reduces make output by ~ 20%)

for _I18N_DYNAMIC, use CSHLIBFLAGS instead of CPICFLAGS.

Split the notion of building Hesiod, Kerberos, S/key, and YP
infrastructure and using that infrastructure in programs.

* MKHESIOD, MKKERBEROS, MKSKEY, and MKYP control building
of the infratsructure (libraries, support programs, etc.)

* USE_HESIOD, USE_KERBEROS, USE_SKEY, and USE_YP control
building of support for using the corresponding API
in various libraries/programs that can use it.

As discussed on tech-toolchain.

refine i18n stuffs.
- add libc/citrus directory.
this directory contains the common stuffs not only for locale
but also other facilities relating to i18n (e.g. iconv).
- To keep the binary compatibility for the ctype modules easily,
the interface between libc and the modules is simplified.
- For the future integrated extension, module pool is renamed
from "/usr/lib/runemodule" to "/usr/lib/i18n".
In the future, this directory will contain the modules for "iconv",
"collation", etc.
- some cosmetic changes.
- Bug fix for runetype.h; __attribute__((__packed__)) is placed at
the wrong position and it is invalid unintentionally.
But, the all members of the structures seem well-aligned. Thus,
this bug causes no problem, hopefully.

HEADS UP:
- /usr/lib/rumemodule is obsoleted. If you use the multibyte locales,
you need to install /usr/lib/i18n/* from sys/lib/i18n_module .
- The binary compatibility of /usr/share/locale/*/LC_CTYPE is probably kept.
Perhaps, the bug fix about __packed__ mentioned above breaks the
compatibility... Be careful especially on 64bit platforms.

No need to reference .OBJDIR here.

Make it possible for ctags to be a host tool.

* Add user-controlled mk.conf variables
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".

- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.

- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs

* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz

* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.

* Always install /sbin/init statically (for now)


The net effect of these changes depends on how the variables are set:

1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so

2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so

3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed

Add pl.msg file to nls/ directory and list it in the Makefile
-- now libc has polish messages

set LANG to "pl" in your environment to use it.

branches: 1.98.2;
I've had it. Raise the barrier on committing unlinted code. On the i386
make lint exit on warnings.

(finally!) enable multibyte LC_CTYPE locale support.

the functionality will be available for dynamic-linked binary only, due to
limitation with dlopen() from within statically-linked binaries.
(statically-linked binary can still enjoy singlebyte LC_CTYPE locale support)

from citrus project.

Remove duplicate "tags" target.

use MACIHNE_CPU to determine architecture-dependent source code directory.
is use of exists(foo) safe enough?
TODO: many other places to fix

prepare for sh3e[bl] split

Create shared ARM source for libc, and move arm26 port over to using it.
The code is (almost) a direct copy of the current arm26 sources.
It's identical to the current arm32 sources, with the following exceptions:
- _C_LABEL is used on references to C labels from assembler.
- Function returns in assembler have APCS-26 versions in #ifdef __APCS_26__.
- It uses SoftFloat 2a rather than SoftFloat 1a.

The first two of these should be inconsequential. I believe that SoftFloat 2a
should work on arm32 and be backward-compatible with existing code, but this
is not obviously true. For now, arm32 remains using its own bits of libc.

Ignore empty translation unit errors.

Don't enable lin's exit on warnings yet. It'll break most ports.

add -w to ctags. got finally tired of looking at all those dup error messages
that nobody will ever fix.

branches: 1.89.2;
Add new RPC code, based on Sun's TI-RPC code. Adapted to not use XTI,
but sockets instead, internally. Old, backward compatible interfaces
maintained.

branches: 1.88.2;
Move dl* function definitions to libc on ELF.
Based on the patch supplied by Takuya Shiozaki <tshiozak@astec.co.jp>.
See http://mail-index.netbsd.org/tech-userlevel/2000/02/23/0000.html.

move -DINET6 upwards, into lib/libc/Makefile.
- we need it for lib/libc/rpc soon
- this is not clear to add CPPFLAGS in subdir/Makefile.inc (as it affect other
subdirs as well)

Fix the tags build.

Add czech language message catalog

branches: 1.84.4;
Revert part of previous and use C/// instead of S/// for mipse[bl]->mips.

-this fancy S/mipse[bl]/mips/ didn't work - replace it by something simple
-generate an ARCHSUBDIR which contains the last path element
-use ${ARCHSUBDIR} instead of ${MACHINE_ARCH} where appropriate

Remap mipse[bl] to mips when finding arch directory.

add sha1 functions, like md5/4

Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

merge nsswitch into main branch

sparc doesn't need quad support when running in 64-bit mode either.

Add _LIBC to the set of preprocessor symbols defined in the libc build
environment; used by source files shared with other parts of the userland
to determine whether certain conventions need to be obeyed or not.

add strchr.c, strrchr.c, memmove.c, memcpy.c, to KSRC for copy to libkern.

Enable quad support on PowerPC.

add bcopy.c to KSRCS, to sync with charles's libkern changes
