* debug/execinfo.h: Remove __THROW from backtrace prototype. 2004-10-22 Jakub Jelinek <jakub@redhat.com> * sysdeps/i386/Makefile (CFLAGS-backtrace.c): Add -fexceptions. * sysdeps/i386/backtrace.c: Include <bits/libc-lock.h>, <dlfcn.h>, <stdlib.h> and <unwind.h>. Remove <bp-checks.h> include. (struct trace_arg): New type. (unwind_backtrace, unwind_getip, unwind_getcfa, unwind_getgr): New fn pointers resp. macros. (init, backtrace_helper): New functions. (__backtrace): Rewritten to use _Unwind_Backtrace first and fall back to frame pointer walking. 2004-10-22 Ulrich Drepper <drepper@redhat.com>
