commit 5e562a69a5432566c6ae78344ae51b80ced7f15b
Author: Tim Moore <timoore@redhat.com>
Date:   Wed Dec 16 12:00:55 2009 +0100

    set the IP in return probes to the returned-to instruction
    
    It's easily available in kretprobes and uretprobes and is consistent
    with the rest of the program state.
    
    * translate.cxx (emit_common_header) : add uretprobe_instance to context.
    * tapsets.cxx (common_probe_entryfn_prologue): Initialize ri in
      context to 0.
      (dwarf_derived_probe_group::emit_module_decls): Change IP to return
      address in kretprobes.
      (uprobe_derived_probe_group::emit_module_decls): enter_uretprobe_probe:
      set ri (uretprobe_instance) in context. Change IP to return
      address in uretprobes. Don't emit uprobe include and #define
    * runtime/runtime.h : Add includes and #define for uprobes.
    * runtime/stack.c (_stp_stack_print, _stp_stack_snprint): Add extra
      argument for uretprobe_instance.
    * tapset/context-unwind.stp (print_backtrace, backtrace): Pass NULL
      for uretprobe_instance to _stp_stack_print.
    * tapset/ucontext-unwind.stp (print_ubacktrace, ubacktrace): pass
      uretprobe_instance to _stp_stack_print
    * testsuite/systemtap.context/uprobe_uaddr.exp : new test for uaddr in
      function probes
    * testsuite/systemtap.context/uprobe_uaddr.stp : new file
