Mon Oct 9 02:54:14 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* Makeconfig (config-LDFLAGS): Define to -Wl-dynamic-linker=$(libdir)$(rtld-installed-name). (rtld-installed-name): New variable. * elf/Makefile (install-lib): Variable removed. (install-others): Define this instead, to $(libdir)(rtld-installed-name). ($(libdir)(rtld-installed-name)): New target; install from ld.so. * elf/ldd.sh.in: New file. * elf/Makefile (distribute): Add ldd.sh.in. (install-bin): Add ldd. ($(objpfx)ldd: ldd.sh.in): New rule. * sysdeps/mach/hurd/dl-sysdep.c: Use __hurd_fail throughout. * hurd/hurd.h (__hurd_fail): Replace macro with inline function. Translate some Mach errors to Hurd errors. * elf/rtld.c (dl_main): Under --list, print msg if executable is statically linked. * elf/dl-load.c (_dl_map_object_from_fd): Rewrote program header table processing. Sat Oct 7 01:25:48 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * sysdeps/stub/machine-gmon.h: Add #error. Fri Oct 6 01:49:48 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * elf/dynamic-link.h (elf_get_dynamic_info): If DYN is null, don't examine it.
