* * elf/dl-deps.c (_dl_map_object_deps): Start TAILP at last preload.Roland McGrath1996-07-141-2/+5
| | | | | | | | | | | | | | | | * elf/dl-open.c (_dl_open): Force an indirect call for _dl_relocate_object so there is no chance a PLT fixup will be done and clobber _dl_global_scope before our call happens. * sysdeps/i386/fpu/__math.h (tan): Correct output constraint from =u to =t; must operate on top of fp reg stack, not second from top. Correct input constraint to 0 from t; must be explicit when input and output are the same register. (floor): Use __volatile instead of volatile. (ceil): Likewise. * manual/Makefile ($(objpfx)stamp%-$(subdir)): Separate rule from other targets.

Sat Jul 13 23:50:17 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * manual/Makefile (lib): New phony target. Depend on stamp files. ($(objpfx)stamp%-$(subdir)): New rule to create them when necessary. 1996-07-13 Paul Eggert <eggert@twinsun.com> * time/strftime.c (strftime): Use space padding for %e, %k, %l, to match Emacs format-time-string specification. (DO_NUMBER_SPACEPAD): Renamed from DO_NUMBER_NOPAD. Sat Jul 13 20:17:38 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * elf/dl-deps.c (_dl_map_object_deps): Take new args PRELOADS and NPRELOADS, vector of `struct link_map *'s; add them to the searchlist between MAP and its deps. * elf/link.h: Fix decl. * elf/rtld.c (dl_main): If not secure, parse LD_PRELOAD for colon-separated list of names, map those and pass vector of ptrs as PRELOADS list to _dl_map_object_deps. * elf/dl-runtime.c (_dl_object_relocation_scope): Pass new args to _dl_map_object_deps with empty preload list. * elf/dl-open.c (_dl_open): Likewise. * sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_open_zero_fill): Function removed.

* * Makerules ($(common-objpfx)libc.so): Depend on $(elfobjdir)/ld.so. cvs/libc-960611Roland McGrath1996-06-101-1/+3

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>
