* elf/dl-close.c (_dl_close): If object has no r_list (i.e., wasn't
loaded directly) determine length if l_initfini list by iterating
over its elements. Minor optimizations.
* elf/dl-deps.c (_dl_map_object_deps): Always add own map to l_initfini
for dependency objects.
If object was already loaded check whether any of the dependencies
is already on the relocation dependency list. If yes, remove the
latter. Minor optimizations.
* elf/dl-lookup.c (add_dependency): Add check for self reference of
maps here. Search l_initfini list only if the object was loaded
directly and not only as a dependency.
(_dl_lookup_symbol): Add relocation dependency also if object
is not in global scope. Remove test for self-reference here.
(_dl_lookup_versioned_symbol): Likewise.
* elf/dl-object (_dl_new_object): Cleanup. Initialize dont_free
element of first name record.
* elf/loadtest.c: Add some more test to recognize early if an object
wasn't unloaded.
* elf/Makefile: Add rules to build and run reldep5.
* elf/reldep5.c: New file.
* elf/reldepmod5.c: New file.
* elf/reldepmod6.c: New file.
* elf/reldep2.c: Fix typo.
* elf/dl-object.c (_dl_new_object): Initialize l_scope and l_scope_max.
This directory contains the version 2.2.4 release of the GNU C Library.
Many bugs have been fixed since the last release.
Some bugs surely remain.
As of this release, the GNU C library is known to run on the following
configurations:
*-*-gnu GNU Hurd
i[3456]86-*-linux-gnu Linux-2.x on Intel
m68k-*-linux-gnu Linux-2.x on Motorola 680x0
alpha*-*-linux-gnu Linux-2.x on DEC Alpha
powerpc-*-linux-gnu Linux and MkLinux on PowerPC systems
sparc-*-linux-gnu Linux-2.x on SPARC
sparc64-*-linux-gnu Linux-2.x on UltraSPARC 64-bit
arm-*-none ARM standalone systems
arm-*-linux Linux-2.x on ARM
arm-*-linuxaout Linux-2.x on ARM using a.out binaries
mips*-*-linux-gnu Linux-2.x on MIPS
ia64-*-linux-gnu Linux-2.x on ia64
s390-*-linux-gnu Linux-2.x on IBM S/390
s390x-*-linux-gnu Linux-2.x on IBM S/390 64-bit
sh-*-linux-gnu Linux-2.x on Super Hitachi
cris-*-linux-gnu Linux-2.4+ on CRIS
Former releases of this library (version 1.09.1 and perhaps earlier
versions) used to run on the following configurations:
alpha-dec-osf1
i[3456]86-*-bsd4.3
i[3456]86-*-isc2.2
i[3456]86-*-isc3
i[3456]86-*-sco3.2
i[3456]86-*-sco3.2v4
i[3456]86-*-sysv
i[3456]86-*-sysv4
i[3456]86-force_cpu386-none
i[3456]86-sequent-bsd
i960-nindy960-none
m68k-hp-bsd4.3
m68k-mvme135-none
m68k-mvme136-none
m68k-sony-newsos3
m68k-sony-newsos4
m68k-sun-sunos4
mips-dec-ultrix4
mips-sgi-irix4
sparc-sun-solaris2
sparc-sun-sunos4
Since no one has volunteered to test and fix the above configurations,
these are not supported at the moment. It's expected that these don't
work anymore. Porting the library is not hard. If you are interested
in doing a port, please contact the glibc maintainers by sending
electronic mail to <bug-glibc@gnu.org>.
There are some add-ons which can be used together with GNU libc. They
are designed in a way to ease the installation by integrating them in
the libc source tree. Simply get the add-ons you need and use the
--enable-add-ons option of the `configure' script to tell where the
add-ons are found. Please read the FAQ file for more details.
See the file INSTALL to find out how to configure, build, install, and port
the GNU C library. You might also consider reading the WWW pages for the
GNU libc at http://www.gnu.org/software/libc/libc.html.
The GNU C Library is completely documented by the Texinfo manual found
in the `manual/' subdirectory. The manual is still being updated and
contains some known errors and omissions; we regret that we do not
have the resources to work on the manual as much as we would like.
Please send comments on the manual to <bug-glibc-manual@gnu.org>, and
not to the library bug-reporting address.
The file NOTES contains a description of the feature-test macros used
in the GNU C library, explaining how you can tell the library what
facilities you want it to make available.
We prefer to get bug reports sent using the `glibcbug' shell script which
is installed together with the rest of the GNU libc to <bugs@gnu.org>.
Simply run this shell script and fill in the information. Nevertheless
you can still send bug reports to <bug-glibc@gnu.org> as normal electronic
mails.
The GNU C Library is free software. See the file COPYING.LIB for copying
conditions.
