2004-11-08 Ulrich Drepper <drepper@redhat.com> * posix/regcomp.c (utf8_sb_map): Define. (free_dfa_content): Don't free dfa->sb_char if it's a pointer to utf8_sb_map. (init_dfa): Use utf8_sb_map instead of initializing memory when the encoding is UTF-8. * posix/regcomp.c (init_dfa): Get the codeset name outside glibc as well. Check if it is spelled UTF8 as well as UTF-8, and check case-insensitively. Set dfa->map_notascii manually when outside glibc. * posix/regex_internal.c (build_wcs_upper_buffer) [!_LIBC]: Enable optimizations based on map_notascii. * posix/regex_internal.h [HAVE_LANGINFO_H || HAVE_LANGINFO_CODESET || _LIBC]: Include langinfo.h. * posix/regex_internal.h (struct re_backref_cache_entry): Add "more" field. * posix/regexec.c (check_dst_limits): Hoist computation of the source and destination bkref_idx out of the loop. Pass it to check_dst_limits_calc_pos. (check_dst_limits_calc_pos_1): New function, containing the recursive loop of check_dst_limits_calc_pos; uses the "more" field of struct re_backref_cache to control the loop. (check_dst_limits_calc_pos): Store into "boundaries" the position relative to lim's start and end positions. Do not accept eclosures, accept bkref_idx instead. Call check_dst_limits_calc_pos_1 to do the work. (sift_states_bkref): Use the "more" field of struct re_backref_cache to control the loop. A big "if" was turned into a continue and the function was reindented. (get_subexp): Use the "more" field of struct re_backref_cache to control the loop. (match_ctx_add_entry): Initialize the bkref_ents' "more" field. (search_cur_bkref_entry): Return -1 if out of bounds. * posix/regexec.c (empty_set): Remove. (sift_states_backward): Remove cur_src variable. Move inner loop to build_sifted_states. (build_sifted_states): Extract from sift_states_backward. Do not use empty_set. (update_cur_sifted_state): Do not use empty_set. Special case dest_nodes->nelem == 0.
This directory contains the version 2.3.3 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 cris-*-linux-gnu Linux-2.4+ on CRIS x86-64-*-linux-gnu Linux-2.4+ on x86-64 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, and LICENSES for notices about a few contributions that require these additional notices to be distributed.
