2003-12-20 Ulrich Drepper <drepper@redhat.com> * sysdeps/unix/sysv/linux/Makefile (CFLAGS-getpid.c): Define. * sysdeps/unix/sysv/linux/getpid.c: New file.
2003-12-17Update.Ulrich Drepper1-2/+7
2003-12-17 Ulrich Drepper <drepper@redhat.com> * elf/rtld.c: Don't use strong_alias to define _rtld_local. This removes the visibility attributes which might be defined earlier for some gcc versions. Instead spell out what strong_alias does plus the visibility.
2003-12-10Update.Ulrich Drepper1-1/+10
2003-12-02 David Mosberger <davidm@hpl.hp.com> * sysdeps/ia64/elf/initfini.c: Add unwind info. * sysdeps/ia64/dl-machine.h (elf_machine_matches_host): Mark with attribute "unused". (elf_machine_dynamic): Mark with attributes "unused" and "const". (elf_machine_runtime_setup): Likewise. * sysdeps/generic/dl-fptr.c (make_fptr_table): Mark with attribute "always_inline". * sysdeps/ia64/dl-machine.h (__ia64_init_bootstrap_fdesc_table): Likewise. * configure.in: Check whether compiler has libunwind support. * config.make.in (have-cc-with-libunwind): New variable. * config.h.in (HAVE_CC_WITH_LIBUNWIND): New macro. * Makeconfig (gnulib): If have-cc-withh-libunwind is "yes", also mention -lunwind. 003-11-12 David Mosberger <davidm@hpl.hp.com> * sysdeps/unix/sysv/linux/ia64/sysdep.h: Define DO_CALL_VIA_BREAK. Redefine DO_CALL to use vdso if supported, otherwise DO_CALL_VIA_BREAK. Likewise for DO_INLINE_SYSCALL. Make INTERNAL_SYSCALL use DO_INLINE_SYSCALL. * sysdeps/unix/sysv/linux/ia64/vfork.S: Use DO_CALL_VIA_BREAK() instead of DO_CALL(). * sysdeps/unix/sysv/linux/ia64/clone2.S: Use break directly instead of DO_CALL(). * sysdeps/unix/sysv/linux/ia64/brk.S (__curbrk): Restructure it to take advantage of DO_CALL() macro. * sysdeps/unix/sysv/linux/ia64/setcontext.S: Likewise. * sysdeps/unix/sysv/linux/ia64/getcontext.S: Likewise. * elf/rtld.c (dl_main): Restrict dl_sysinfo_dso check to first program header. On ia64, the check failed previously because there are two program headers. * sysdeps/generic/s_nexttowardf.c: Likewise. * math/bug-nexttoward.c: New file.
2003-11-26Update.Ulrich Drepper1-0/+9
2003-11-21 David Mosberger <davidm@hpl.hp.com> * elf/soinit.c (_fini): Put _fini() in .init_array section if HAVE_INITFINI_ARRAY is defined.
2003-11-26Update.Ulrich Drepper3-1/+21
2003-11-25 Ulrich Drepper <drepper@redhat.com> * posix/runptests.c (main): Make errors fatal. * posix/PTESTS: One test in GA135 and GA136 check functionality which seems not guaranteed. 2003-11-25 Jakub Jelinek <jakub@redhat.com> * posix/regexec.c (re_search_internal): If prune_impossible_nodes returned REG_NOMATCH, set match_last to -1. Don't initialize pmatch[0] needlessly. Fix comment. (prune_impossible_nodes): Don't segfault on NULL state_log entry. (set_regs): Fix comment. * posix/regcomp.c (parse_bracket_exp): Only set has_plural_match if adding both SIMPLE_BRACKET and COMPLEX_BRACKET. (build_charclass_op): Set has_plural_match if adding both SIMPLE_BRACKET and COMPLEX_BRACKET. * posix/bug-regex11.c (tests): Fix register values for one commented out test. Add new tests. * posix/regex_internal.c (re_string_allocate): Make sure init_len is at least dfa->mb_cur_max. (re_string_reconstruct): If is_utf8, don't fall back into re_string_skip_chars just because idx points into a middle of valid UTF-8 character. Instead, set the wcs bytes which correspond to the partial character bytes to WEOF. * posix/regexec.c (re_search_internal): Allocate input.bufs_len + 1 instead of dfa->nodes_len + 1 state_log entries initially. * posix/bug-regex20.c (main): Uncomment backwards case insensitive tests.
2003-10-27Update.Ulrich Drepper1-1/+2
* elf/rtld.c (map_doit): Pass __RTLD_OPENEXEC in last parameter to _dl_map_object.
2003-10-27Update.Ulrich Drepper1-1/+1
* elf/sprof.c (load_shobj): Use l_map_start not l_addr to locate ELF header.
