Update.
2003-01-11 Jim Meyering <jim@meyering.net> * io/ftw.c [HAVE_CONFIG_H]: Include <config.h>. [HAVE_SYS_PARAM_H || _LIBC]: Guard inclusion of <sys/param.h>. Include <sys/stat.h>, not <include/sys/stat.h>, if !_LIBC. [!_LIBC] (__chdir, __closedir, __fchdir, __getcwd, __opendir): Define. [!_LIBC] (__readdir64, __tdestroy, __tfind, __tsearch): Define. [!_LIBC] (internal_function, dirent64, MAX): Define. (__set_errno): Define if not already defined. (open_dir_stream): When FTW_CHDIR is enabled, invoke opendir on the basename, not the entire file name. (process_entry): When FTW_CHDIR is enabled, invoke XSTAT or LXSTAT on the basename, not the entire file name. 2003-01-12 Ulrich Drepper <drepper@redhat.com> * string/tester.c (test_strcpy): Disable last added strcpy until it is fixed. 2003-01-11 Philip Blundell <philb@gnu.org> * sysdeps/unix/sysv/linux/arm/socket.S: Add cancellation support. 2003-01-11 Andreas Schwab <schwab@suse.de> * Makerules: Add vpath for %.dynsym and %.so so that the implicit rule chaining for check-abi works. 2003-01-11 Kaz Kojima <kkojima@rr.iij4u.or.jp> * sysdeps/unix/sysv/linux/sh/sysdep.h (SYSCALL_ERROR_HANDLER): Add non-PIC case. 2003-01-11 Jakub Jelinek <jakub@redhat.com> * elf/tls-macros.h [__ia64__] (__TLS_CALL_CLOBBERS): Define. [__ia64__] (TLS_LE, TLS_IE): Fix typos. Add ;; at start of asm if gp is used early. [__ia64__] (TLS_LD, TLS_GD): Likewise. Use __TLS_CALL_CLOBBERS. * elf/Makefile ($(objpfx)tst-tlsmod5.so, $(objpfx)tst-tlsmod6.so): Ensure libc.so in DT_NEEDED. * sysdeps/alpha/dl-machine.h (elf_machine_rela): Move CHECK_STATIC_TLS before l_tls_offset use. * sysdeps/i386/dl-machine.h (elf_machine_rel, elf_machine_rela): Likewise. * sysdeps/sh/dl-machine.h (elf_machine_rela): Likewise. * sysdeps/generic/dl-tls.c (_dl_allocate_tls_storage) [TLS_DTV_AT_TP]: Allocate TLS_PRE_TCB_SIZE bytes below result. (_dl_deallocate_tls) [TLS_DTV_AT_TP]: Adjust before freeing. * sysdeps/generic/libc-tls.c (__libc_setup_tls): If TLS_INIT_TP_EXPENSIVE is not defined, allocate even if no PT_TLS segment has been found. If TLS_DTV_AT_TP, allocate TLS_PRE_TCB_SIZE bytes below result and add tcb_offset to memsz. * sysdeps/ia64/dl-tls.h (__tls_get_addr): New prototype. * sysdeps/ia64/dl-machine.h: Include tls.h. (elf_machine_type_class): Return ELF_RTYPE_CLASS_PLT for TLS relocs too. (elf_machine_rela): Assume if sym_map != NULL sym is non-NULL too. Handle R_IA64_DTPMOD*, R_IA64_DTPREL* and R_IA64_TPREL* relocations. * sysdeps/ia64/libc-tls.c: New file. 2003-01-10 Steven Munroe <sjmunroe@us.ibm.com> * sysdeps/powerpc/powerpc64/sysdep.h (PSEUDO_RET): Add branch hit. * sysdeps/unix/sysv/linux/powerpc/bits/stat.h (STAT_VER_LINUX): Fix type. Move definition out of #if. * sysdeps/unix/sysv/linux/powerpc/powerpc64/ftruncate64.c: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc64/pread.c: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc64/pread64.c: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc64/pwrite.c: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc64/pwrite64.c: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc64/socket.S: Add cancellation support. * sysdeps/unix/sysv/linux/powerpc/powerpc64/syscalls.list: Remove ftruncate64, pread64, pwrite64, truncate64 entries. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h (INLINE_SYSCALL): New version that supports function call like syscalls. Add __builtin_expect. (LOADARGS_n): Add argument size safety checks. (INTERNAL_SYSCALL): New Macro. * sysdeps/unix/sysv/linux/powerpc/powerpc64/truncate64.c: New file. * sysdeps/unix/sysv/linux/powerpc/sys/procfs.h [__PPC_ELF_H]: Avoid redefinition of elf_fpreg_t and elf_fpregset_t. 2003-01-12 Ulrich Drepper <drepper@redhat.com> * elf/dl-close.c (_dl_close): Add several asserts. Correct and simplify test for unloading. If loader of a DSO is unloaded do not use its scope anymore. Fall back to own scope and adjust opencounts. Fix several comments. * elf/dl-deps.c (_dl_map_object_deps): Always allocate memory for the l_searchlist, not only for l_initfini. * elf/dl-lookup.c (add_dependencies): Avoid creating relocation dependencies if objects cannot be removed. Remove object with the definition as not unloadable if necessary. * elf/reldep6.c: Create relocation dependency before closing the first module. 2003-01-10 Guido Günther <agx@sigxcpu.org> * elf/Makefile: Add rules to build and run reldep9 test. * elf/reldep9.c: New file. * elf/reldep9mod1.c: New file. * elf/reldep9mod2.c: New file. * elf/reldep9mod3.c: New file. 2003-01-09 Jakub Jelinek <jakub@redhat.com> * elf/Makefile: Add rules to build and run nodelete2 test. * elf/nodelete2.c: New file. * elf/nodel2mod1.c: New file. * elf/nodel2mod2.c: New file. * elf/nodel2mod3.c: New file. 2003-01-09 Jakub Jelinek <jakub@redhat.com>
