879bf2e65a * sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start): If started by
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.

91f62ce6b5 (rtld_command): Variable removed. (_dl_skip_args): New variable. (dl_main): Increment _dl_skip_args instead of setting rtld_command. If the link_map for the executable itself is not first in the chain, make it so. 1995-09-28 17:05:33 +00:00

f2b0f935d7 * elf/dl-load.c (_dl_map_object): Add MAP_INHERIT flag in mmap
from zero fill.

	* elf/dl-lookup.c (_dl_lookup_symbol): Take new flag arg NOSELF;
 	if nonzero, don't let *REF satisfy the reference itself.
	* elf/link.h (_dl_lookup_symbol): Add new arg NOSELF in decl.
	* sysdeps/i386/dl-runtime.c (_dl_runtime_resolve): Pass new arg to
 	_dl_lookup_symbol.
	* elf/do-rel.h (elf_dynamic_do_rel): Pass new second arg of
 	R->r_offset to RESOLVE callback.
	* elf/dl-reloc.c (_dl_relocate_object: resolve): Don't let *REF
 	satisfy the reference itself if its value equals the reloc's
 	offset.

	* elf/rtld.c (dl_main): Write a newline in fatal msg.

	* Makerules (lib%.so: lib%_pic.a): Pass $(LDFLAGS.so).

* elf/rtld.c [! NDEBUG] (__assert_perror_fail): New function.

	* hurd/hurdstartup.c (_hurd_startup): Fancier kludge to guess phdr
 	and user entry point addresses.

	* elf/dl-load.c (open_path): Don't do strlen on DIRPATH if it's null.
	(_dl_map_object): DT_RPATH value is relative to DT_STRTAB value.

	* Makerules (install-lib.so): Don't include libc.so.
	[$(build-shared)=yes] (install): Depend on the installed libc.so file.
	[$(build-shared)=yes] (install-no-libc.a): Make this, rather than
	install, depend on the installed $(install-lib.so) files.
	[$(build-shared)=yes] (install-lib.so): Append libc.so after that rule.

	* sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start): Add kludge to
 	allocate high addresses to avoid random mappings appearing there.
	(mmap): Comment out mask; always pass zero.

	* sysdeps/i386/dl-machine.h (ELF_MACHINE_USER_ADDRESS_MASK): New macro.
	* sysdeps/mach/hurd/dl-sysdep.c (mmap): Use it as mask in vm_map call.

	* elf/dl-error.c (_dl_catch_error): Clear *ERRSTRING and *OBJNAME
 	when successful.

	* sysdeps/mach/hurd/dl-sysdep.c (threadvars): New static variable.
	(__hurd_threadvar_max, __hurd_threadvar_stack_offset): Define these
	variables, using the `threadvars' buffer.

	* elf/dl-reloc.c: Don't dereference L->l_prev when it's null.
	* sysdeps/i386/dl-runtime.c: Likewise.

	* elf/rtld.c (dl_main): Add missing NULL terminating argument in
 	_dl_sysdep_fatal call.
	(__assert_fail): Likewise.

	* locale/Makefile (localedef-modules): Renamed ctype to
 	locale-ctype so as not to conflict with the object file for
 	ctype/ctype.c in the build directory.

	* sysdeps/i386/dl-machine.h (elf_machine_rel): If MAP->l_type is
 	lt_interpreter, first undo relocation done during bootstrapping.

* mach/Makefile (server-interfaces): Removed notify and

 	not refer to any functions not defined in libc.

* Makeconfig (+gccwarn): Add -Winline.

	* hurd/hurdsig.c (_hurd_internal_post_signal): If SS->context is

 	from SS->context.  Don't clear SS->context.
