Update.
1998-08-26 17:48 Ulrich Drepper <drepper@cygnus.com> * elf/dl-close.c (_dl_close): Move map->l_nsearchlist value into local variable so that map can be freed. Reported by Philippe Troin <phil@fifi.org>. * elf/dl-open.c (dl_open_worker): Correct test for extending global scope array. Patch by Philippe Troin <phil@fifi.org>. 1998-08-26 Geoff Keating <geoffk@ozemail.com.au> * sysdeps/powerpc/register-dump.h: Rewrite. Much nicer this way. Don't call writev() with a 100-element vector. * sysdeps/generic/segfault.c (catch_segfault): Skip top-level NULL return address. * sysdeps/powerpc/elf/libc-start.c: Sync up with generic version. In particular, set __libc_stack_end. * sysdeps/powerpc/elf/start.S: Allow _init and _fini to be undefined. Fix copyright notice. 1998-08-25 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * math/Makefile (gmp-objs): New variable. ($(objpfx)atest-exp, $(objpfx)atest-sincos, $(objpfx)atest-exp2): Depend on it. (tests): Add atest-exp atest-sincos atest-exp2. (tests-static): Remove atest-exp atest-sincos atest-exp2. * elf/rtld.c (dl_main): Unload map file before jumping to user code.
