* elf/dl-lookup.c (_dl_lookup_symbol): If no value and *REF is null, consider it a strong reference and give the error. Wed Jun 12 15:52:46 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * elf/dl-open.c (_dl_open): Correctly terminate relocating loop after relocating NEW when it's the only new object. * elf/dl-init.c (_dl_init_next): When out of initializers, set _r_debug.r_state to RT_CONSISTENT and call _dl_debug_state just before return. * elf/rtld.c (dl_main): Move _dl_debug_initialize call after relocation. Call it unconditionally and only fill in DT_DEBUG if it's present. Then call _dl_debug_state with r_state RT_ADD before running initializers. * elf/dl-open.c (_dl_open): Call _dl_debug_initialize and then call _dl_debug_state with r_state RT_ADD before running initializers * elf/dl-close.c (_dl_close): Call _dl_debug_state with r_state RT_DELETE before running finalizers and with RT_CONSISTENT just before return. * elf/Makefile (dl-routines): Add dl-debug. * elf/dl-debug.c: New file. * elf/rtld.c (_dl_r_debug): Rename to _r_debug and move to dl-debug.c. (_dl_r_debug_state): Rename to _dl_debug_state and likewise move. (dl_main): Use _dl_debug_initialize. * elf/link.h: Fix name to _dl_debug_state in decl. (_dl_debug_initialize): Declare new function from dl-debug.c. (_r_debug): Declare it. * Makerules (distinfo-vars): Add install-{lib,data,bin,sbin,others}. In distinfo set $(subdir)-VAR and then set VAR to $($(subdir)-VAR). * Makeconfig (rpath-link): New variable; add $(elfobjdir). (default-rpath): Use it. (built-program-cmd): Use it in LD_LIBRARY_PATH. * Makeconfig (sysdep-configures): Prepend $(sysdep_dir) to names tried. * sysdeps/unix/Dist: Add make-syscalls.sh. * misc/Makefile (headers): Add sys/swap.h. * posix/unistd.h: Remove decls for swapon, swapoff. * sysdeps/generic/sys/swap.h: New file. * sysdeps/unix/sysv/linux/sys/swap.h: New file. * sysdeps/unix/sysv/linux/gnu/types.h: Remove temporary hack #define of __kernel_fsid_t. It is correctly defines in <linux/types.h> now.

* sysdeps/mach/hurd/dl-sysdep.c (__open): Define this instead of open. (__close, __mmap): Likewise define with __ names now. Mon Jun 10 05:13:18 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * elf/dl-support.c: New file. * elf/Makefile (CFLAGS-dl-support.c): New variable. (routines, elide-routines.so): Add dl-support. * elf/dl-minimal.c (_dl_pagesize): Remove common defn. * elf/dl-load.c (_dl_pagesize): Define it here. (_dl_map_object_from_fd): Initialize it if zero. * elf/link.h (_dl_pagesize): Remove const. Sun Jun 9 04:04:26 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * elf/Makefile (routines): Add dl-symbol. * elf/dl-lookup.c (_dl_symbol_value): Moved to ... * elf/dl-symbol.c: New file. * elf/elf.h (Elf32_Xword, Elf32_Sxword): New types. (Elf32_Section, Elf64_Section): New types, 16 bits. (Elf32_Sym, Elf64_Sym): Use it. * elf/dl-deps.c (_dl_open): Moved to ... * elf/dl-open.c: New file. * Makefile (routines): Add dl-open. * elf/Makefile (dl-routines): New variable. (routines): Add $(dl-routines). (elide-routines.so): New variable, set to $(dl-routines). (libdl-inhibit-o): Variable removed; build all flavors of -ldl. (rtld-routines): All but rtld, dl-sysdep, and dl-minimal moved to $(dl-routines). * elf/dl-lookup.c (_dl_lookup_symbol): Remove magic symbol grokage. * elf/dladdr.c: Use ELFW(ST_BIND) in place of ELF32_ST_BIND. * elf/dl-load.c (open_path): Use __ names for open and close. Avoid using strdup. (_dl_map_object): Likewise. (_dl_map_object_from_fd): Use __ names for mmap, munmap, and mprotect. * elf/dl-minimal.c (malloc): Likewise. * elf/dl-reloc.c (_dl_relocate_object): Likewise. * elf/dl-minimal.c (_dl_pagesize): New variable. (malloc): Use that instead of a static variable. * elf/dl-reloc.c (_dl_relocate_object): Use _dl_pagesize instead of calling getpagesize. * elf/dl-load.c (_dl_map_object_from_fd): Likewise. * elf/link.h: Declare _dl_pagesize. * elf/rtld.c (dl_r_debug): Renamed to _dl_r_debug. * elf/link.h (struct link_map): Use Half for l_phnum instead of Word. * elf/rtld.c (dl_main): Use Half for phdr count arg. (_dl_sysdep_start): Update prototype of DL_MAIN function ptr arg. * elf/dl-load.c (_dl_map_object_from_fd): Use explicit Elf32_Word to extract 4-byte magic number, not ElfW(Word). Match EI_CLASS against native wordsize, either 32 or 64. * elf/elf.h (Elf64_Byte, Elf64_Section): Typedefs removed. In C a char is always a byte, no need for a typedef. Section indices are 16-bit quantities in elf64, which already have a typedef Elf64_Half. Remove partial -lelf implementation. There is now a separately-distributed `libelf' package that implements it. * elf/dl-lookup.c: Don't #include <libelf.h> any more. (_dl_elf_hash): New function, moved from libelf.h:elf_hash. (_dl_lookup_symbol): Use it instead of elf_hash. * elf/libelf.h: File removed. * elf/elf_hash.c: File removed. * elf/Makefile (headers): Remove libelf.h. (extra-libs): Remove libelf. (libelf-routines): Variable removed. * elf/Makefile (libdl.so): Remove commands from this target. The implicit rule commands are correct, this explicit rule just serves to add some dependencies. * elf/dl-lookup.c (_dl_lookup_symbol): Use ELFW(ST_TYPE) in place of ELF32_ST_TYPE. Likewise ST_BIND. * elf/do-rel.h (elf_dynamic_do_rel): Likewise R_SYM. * elf/link.h (ElfW): New macro for wordsize-independent ElfXX_* type naming. (ELFW): New macro, likewise for ELFXX_* macro naming. (_ElfW, _ElfW_1): New macros, subroutines of ElfW and ELF. Sat Jun 8 20:52:38 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * elf/link.h, elf/do-rel.h, elf/dynamic-link.h, elf/dl-deps.c, elf/dl-init.c, elf/dl-load.c, elf/dl-lookup.c, elf/dl-reloc.c, elf/dl-runtime.c, elf/dladdr.c, elf/dlclose.c, elf/dlsym.c, elf/linux-compat.c, elf/rtld.c: Change all uses of `Elf32_XXX' to `ElfW(XXX)' for wordsize-independence. Sat Jun 8 20:50:42 1996 Richard Henderson <rth@tamu.edu> * elf/elf.h: Move Elf64_* types in parity with Elf32 counterparts. (Elf64_auxv_t): New type. (EM_ALPHA, R_ALPHA_*): New macros for elf64-alpha format.

* elf/dladdr.c: Remove #include <setjmp.h>, we don't use it. * shlib-versions: Set libdl=2. * elf/dl-deps.c (_dl_map_object_deps): Use a linked list of alloca'd elements and then scan it to fill the single malloc'd array, instead of using realloc to grow the array in the first pass. _dl_map_object may do some mallocs that break our stream of reallocs, and the minimal realloc can't handle that. * elf/dl-init.c (_dl_init_next): Take argument, link_map whose searchlist describes the piece of the DT_NEEDED graph to be initialized. * elf/link.h: Update prototype. * sysdeps/i386/dl-machine.h (RTLD_START): Pass _dl_loaded as argument to _dl_init_next. * sysdeps/m68k/dl-machine.h: Likewise. * elf/dl-deps.c (_dl_open): Pass new object as arg to _dl_init_next. * elf/link.h (struct link_map): Add `l_reserved' member, soaking up extra bits in last byte. * elf/dl-deps.c (_dl_map_object_deps): Use that for mark bit to avoid putting dup elts in search list. * elf/dlclose.c: Use MAP->l_searchlist to find deps to close. * elf/dlsym.c: Don't tweak linked list. Scope array given to _dl_lookup_symbol does the right thing. Tue Jun 4 02:25:44 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
1995-12-12RegeneratedRoland McGrath
Fri Dec 8 13:04:51 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * posix/glob.c: Implement new options GLOB_ALTDIRFUNC, GLOB_BRACE, GLOB_TILDE, GLOB_NOMAGIC. (glob): Use stat instead of lstat to determine directoriness. * posix/glob.h (GLOB_ALTDIRFUNC, GLOB_BRACE, GLOB_NOMAGIC, GLOB_TILDE): New flag bits. (__GLOB_FLAGS): Include them. (glob_t): New members gl_closedir, gl_readdir, gl_opendir, gl_lstat, gl_stat.
1995-09-30* sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start): If started byRoland McGrath
kernel with args on stack, point _dl_hurd_data at zero data instead of garbage. When ld.so run as program, grok args -LIB=MEMOBJ and pre-load shared object files found in memory objects loaded by the boot loader. * elf/link.h (struct link_map): New member `l_entry'. (_dl_map_object, _dl_map_object_from_fd): Remove last arg ENTRY_POINT. * elf/dl-load.c (_dl_map_object, _dl_map_object_from_fd): Remove last arg ENTRY_POINT. Store the entry point location in the `l_entry' member of the new map. * elf/rtld.c (dl_main): Don't pass USER_ENTRY arg to _dl_map_object. When run as program, set *USER_ENTRY to L->l_entry. * elf/dl-init.c (_dl_init_next): Don't pass ENTRY_POINT arg to _dl_map_object.
1995-05-31Tue May 30 15:52:32 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>Roland McGrath
* mach/Makefile (server-interfaces): Removed notify and device_reply. For shlibs with eager binding, libmachuser.so must not refer to any functions not defined in libc.
