(_dl_close): If called recursively, just remember GC needs to be rerun
and decrease l_direct_opencount. Avoid GC if l_direct_opencount
decreased to 1. Rerun GC at the end if any destructor unloaded some
additional libraries.
* elf/Makefile: Add rules to build and run unload6 test.
* elf/unload6.c: New test.
* elf/unload6mod1.c: New file.
* elf/unload6mod2.c: New file.
* elf/unload6mod3.c: New file.
* malloc/hooks.c (mem2chunk_check): Add magic_p argument, set *magic_p
if magic_p is not NULL.
(top_check): Invoke MALLOC_FAILURE_ACTION if MORECORE failed.
(malloc_check): Fail if sz == -1.
(free_check): Adjust mem2chunk_check caller.
(realloc_check): Likewise. Fail if bytes == -1. If bytes == 0 and
oldmem != NULL, call free_check and return NULL. If reallocating
and returning NULL, invert magic byte again to make oldmem valid
region for further checking.
(memalign_check): Fail if bytes == -1.
* malloc/Makefile: Add rules to build and run tst-mcheck.
* malloc/tst-mcheck.c: New test.
This directory contains the version 2.3.4 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
powerpc64-*-linux-gnu Linux-2.4.19+ on 64-bit 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-2.4+ on IBM S/390 64-bit
sh-*-linux-gnu Linux-2.x on Super Hitachi
x86-64-*-linux-gnu Linux-2.4+ on x86-64
Past releases of this library ran on a variety of configurations that are
no longer supported. Porting the library is not hard. If you are
interested in doing a port, please contact the glibc maintainers;
see http://www.gnu.org/software/libc/ for more information.
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.
Please see http://www.gnu.org/software/libc/bugs.html for bug reporting
information. We are now using the Bugzilla system to track all bug reports.
This web page gives detailed information on how to report bugs properly.
The GNU C Library is free software. See the file COPYING.LIB for copying
conditions, and LICENSES for notices about a few contributions that require
these additional notices to be distributed.
