1998-09-06 09:00 Ulrich Drepper <drepper@cygnus.com> * version.h (VERSION): Bump to 2.0.96. Rewrite runtime linker to be truly thread-safe. There is now no global variable specifying the scope. We create all needed scopes at the time the link maps are created. * elf/Versions [GLIBC_2.1]: Add _dl_loaded and _dl_main_searchlist. * elf/link.h: Add struct r_scope_elem and use this for l_searchlist, l_symbolic_searchlist, l_scope, and l_local_scope elements in struct link_map. * elf/dl-close.c: Rewritten accordingly. * elf/dl-deps.c: Likewise. * elf/dl-error.c: Likewise. * elf/dl-init.c: Likewise. * elf/dl-load.c: Likewise. * elf/dl-lookup.c: Likewise. * elf/dl-object.c: Likewise. * elf/dl-open.c: Likewise. * elf/dl-reloc.c: Likewise. * elf/dl-runtime.c: Likewise. * elf/dl-support.c: Likewise. * elf/dl-symbol.c: Likewise. * elf/dl-version.c: Likewise. * elf/dlfcn.h: Likewise. * elf/dlsym.c: Likewise. * elf/dlvsym.c: Likewise. * elf/ldsodefs.h: Likewise. * elf/rtld.c: Likewise. * iconv/gconv_dl.c: Likewise. * nss/nsswitch.c: Likewise. * sysdeps/i386/dl-machine.h: Likewise. * sysdeps/unix/sysv/linux/i386/dl-librecon.h: Likewise.
