Hi Michael, I try the 20080930 branch and got: (gdb) start Temporary breakpoint 1 at 0x80483c1: file 1.c, line 20. Starting program: /home/teawater/rec/a.out Temporary breakpoint 1, main () at 1.c:20 20 int b = 0; (gdb) record (gdb) n 21 int c = 1; (gdb) 24 printf ("a = %d b = %d c = %d\n", a, b, c); (gdb) a = 0 b = 0 c = 1 25 b = cool (); (gdb) rn No more reverse-execution history. main () at 1.c:20 20 int b = 0; (gdb) n Cannot find bounds of current function This is because: case TARGET_WAITKIND_NO_HISTORY: /* Reverse execution: target ran out of history info. */ print_stop_reason (NO_HISTORY, 0); stop_stepping (ecs); return; This place doesn't set stop_pc but in step_1: if (find_pc_partial_function (stop_pc, &name, &tp->step_range_start, &tp->step_range_end) == 0) error (_("Cannot find bounds of current function")); So I add code to set stop_pc. I think this bug will affect main tree too. So this patch is for both 20080930 branch and main tree. 2008-10-19 Hui Zhu <teawater@gmail.com> * infrun.c (handle_inferior_event): Set "stop_pc" when TARGET_WAITKIND_NO_HISTORY. Thanks, Hui
