Update.
1999-12-17 Ulrich Drepper <drepper@cygnus.com> * string/bits/string2.h (__strtok_r_1c): Help gcc optimizing string access. * locale/programs/ld-collate.c: Implement handling of absolute ellipsis. Parsing of file and constructing the internal data structures should now be complete. (collate_finish): Start adding support to generate the data structures which are written out to the file. * intl/dcgettext.c: Rewrite to handle caching of previous results here instead of in the dcgettext macro. * intl/libintl.h (dcgettext): Don't define for systems using this glibc or systems with tsearch. * sysdeps/generic/mathdef.h: Protect definitions for math.h against double inclusion. * sysdeps/alpha/fpu/bits/mathdef.h: Likewise. * sysdeps/i386/fpu/bits/mathdef.h: Likewise. * sysdeps/m68k/fpu/bits/mathdef.h: Likewise. * sysdeps/powerpc/fpu/bits/mathdef.h: Likewise. * sysdeps/i386/fpu/libm-test-ulps: Add more deltas (are mobile PIIs that different?). 1999-12-17 Andreas Jaeger <aj@suse.de> * rt/aio.h (struct aiocb64): Add member __next_prio to sync the struct with aiocb. * rt/Makefile (tests): Added tst-aio64. Added dependency rules for tst-aio64. * rt/tst-aio64.c: New file, copied from tst-aio.c and changed for 64bit tests. 1999-12-15 Thorsten Kukuk <kukuk@suse.de> * sysdeps/unix/sysv/linux/alpha/oldgetrlimit64.c: Removed. * sysdeps/unix/sysv/linux/alpha/oldsetrlimit64.c: Removed. * sysdeps/unix/sysv/linux/bits/resource.h: Change RLIM_INFINITY back to old value (signed long). * sysdeps/unix/sysv/linux/i386/bits/resource.h: New, with unsigned long RLIM_INFINITY. * sysdeps/unix/sysv/linux/getrlimit.c: Moved from here to ... * sysdeps/unix/sysv/linux/i386/getrlimit.c: ... here. * sysdeps/unix/sysv/linux/getrlimit64.c: Moved from here to ... * sysdeps/unix/sysv/linux/i386/getrlimit64.c: ... here. * sysdeps/unix/sysv/linux/oldgetrlimit64.c: Moved from here to ... * sysdeps/unix/sysv/linux/i386/oldgetrlimit64.c: ... here. * sysdeps/unix/sysv/linux/oldsetrlimit64.c: Moved from here to ... * sysdeps/unix/sysv/linux/i386/oldsetrlimit64.c: ... here. * sysdeps/unix/sysv/linux/setrlimit.c: Moved from here to ... * sysdeps/unix/sysv/linux/i386/setrlimit.c: ... here. * sysdeps/unix/sysv/linux/setrlimit64.c: Moved from here to ... * sysdeps/unix/sysv/linux/i386/setrlimit64.c: ... here. * sysdeps/unix/sysv/linux/sparc/bits/resource.h: New. * sysdeps/unix/sysv/linux/sparc/sparc64/oldgetrlimit64.c: Removed. * sysdeps/unix/sysv/linux/sparc/sparc64/oldsetrlimit64.c: Removed. 1999-12-17 Andreas Jaeger <aj@suse.de> * elf/ldconfig.c: Add new option -l to manualy link shared libraries. (options): Added option. (parse_opt): Set option. (main): Handle option. (manual_link): New function. 1999-12-17 Thorsten Kukuk <kukuk@suse.de> * string/bits/string2.h: Fix patch from 1999-12-07. 1999-12-16 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/strsep.c: If delim string has only one character don't run over end of string. * locale/programs/ld-collate.c (insert_weights): Also update next pointer of last cursor element. (insert_value): Return nonzero value if nothing got inserted. (handle_ellipsis): Don't do anything if to-value cannot be inserted. 1999-12-10 Jakub Jelinek <jakub@redhat.com> * stdlib/longlong.h (__sparc_v9__): Use %rDIGIT instead of %DIGIT where appropriate. 1999-12-10 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/sparc/sparc64/sigaction.c (__sigaction): Copy sa_flags into kernel sigaction structure. 1999-12-14 Andreas Jaeger <aj@suse.de> * string/tester.c (test_strsep): More tests for access beyond the final NUL. The first two tests come from PR libc/1486 by martinea@iro.umontreal.ca. 1999-12-14 Thorsten Kukuk <kukuk@suse.de> * nis/ypclnt.c: Correct handling of cached client handles. (__xdr_ypresp_all): Call callback function for errors, too, like Solaris does. * nis/nss_compat/compat-grp.c: Make sure errno is always set correct. * nis/nss_compat/compat-initgroups.c: Likewise. * nis/nss_compat/compat-spwd.c: Likewise. * nis/nss_nis/nis-alias.c: Likewise. * nis/nss_nis/nis-ethers.c: Likewise. * nis/nss_nis/nis-grp.c: Likewise. * nis/nss_nis/nis-hosts.c: Likewise. * nis/nss_nis/nis-netgrp.c: Likewise. * nis/nss_nis/nis-publickey.c: Likewise. * nis/nss_nis/nis-service.c: Likewise. Also use services.byservicename Map if available, optimize query if name/port and protocol is known.
