* 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.
Tue Jun 6 13:34:53 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* 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.
