Fri Oct 31 01:47:57 1997 Jason Merrill <jason@yorick.cygnus.com> Support for nested exceptions. * tinfo2.cc (__is_pointer): New fn. * exception.cc (struct cp_eh_info): Define. (__cp_exception_info, __uncatch_exception): New fns. (__cp_push_exception, __cp_pop_exception): New fns. * except.c: Lose saved_throw_{type,value,cleanup,in_catch}. Lose empty_fndecl. (init_exception_processing): Likewise. __eh_pc is now external. (push_eh_info): New fn. (get_eh_{info,value,type,caught}): New fns. (push_eh_cleanup): Just call __cp_pop_exception. (expand_start_catch_block): Use push_eh_info. Start the eh region sooner. (expand_end_eh_spec): Use push_eh_info. (expand_throw): Call __cp_push_exception to set up the exception info. Just pass the destructor or 0 as the cleanup. Call __uncatch_exception when we rethrow. (expand_builtin_throw): Don't refer to empty_fndecl. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@16248 138bc75d-0d04-0410-961f-82ee72b054a4
