[(NEED_DL_SYSINFO || NEED_DL_SYSINFO_DSO) && SHARED]: Scan GLRO(dl_sysinfo_map) for PT_NOTE giving Linux kernel version, we can skip the uname call if it's there. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Don't use DL_SYSDEP_OSCHECK here. * elf/rtld.c (dl_main) [DL_SYSDEP_OSCHECK]: Do it here instead. * sysdeps/generic/ldsodefs.h (struct rtld_global_ro): Add _dl_sysinfo_map. * elf/rtld.c (dl_main): Don't call _dl_init_paths early in the rtld_is_main case. Call it unconditionally later. Move GLRO(dl_sysinfo_dso) handling earlier, before _dl_init_paths call. Initialize GLRO(dl_sysinfo_map). * elf/dl-load.c (open_path): Bail out if _dl_init_paths wasn't called. * sysdeps/generic/dl-sysdep.c (_DL_FIRST_EXTRA): New macro. (_dl_important_hwcaps) [(NEED_DL_SYSINFO || NEED_DL_SYSINFO_DSO) && SHARED]: Scan GLRO(dl_sysinfo_map) for PT_NOTE giving synthetic hwcap names and bit values. * elf/ldconfig.c (_DL_FIRST_EXTRA): New macro. (hwcap_extra): New static variable. (is_hwcap_platform): Check hwcap_extra for a matching name. Remove tls special case. (path_hwcap): Likewise. (parse_conf): Parse "hwcap" directive to define synthetic hwcap bits and their names, stored in hwcap_extra. (main) [USE_TLS]: Initialize final synthetic hwcap bit as "tls". * sysdeps/generic/ldsodefs.h (struct rtld_global_ro): Use uint64_t for _dl_hwcap and _dl_hwcap_mask. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Cast a_val for AT_HWCAP to unsigned long int. * elf/dl-support.c (_dl_aux_init): Likewise. (_dl_hwcap): Update defn. * elf/cache.c (print_entry): Pad hwcap value with 0s in diagnostic. * elf/ldconfig.c (search_dir): Likewise. |

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.
