commit a057c85c16c0d318ab6c837481417cac6801bd45
Author: Mark Wielaard <mjw@redhat.com>
Date:   Fri Jun 11 14:57:13 2010 +0200

    Consolidate task_finder/vma tracker initialization.
    
    After the task_finder is started, no new targets can reliably be added.
    So make sure that all registration/enabling of the task_finder and/or
    the vma tracker is done in one place (task_finder_derived_probe_group).
    
    * task_finder.h: Defined enable_vma_tracker and vma_tracker_enabled.
    * task_finder.cxx: Implement enable_vma_tracker and vma_tracker_enabled.
      (task_finder_derived_probe_group::emit_module_init): Also handle
      vma_tracker.
    * elaborate.cxx (visit_embeddedcode): Use enable_vma_tracker and
      vma_tracker_enabled.
    * session.h (systemtap_session): Remove need_vma_tracker.
    * session.cxx (initialize): Remove need_vma_tracker initialization.
      (parse_cmdline): Enable vma tracking early when -d user mode module found.
    * translate.cxx (c_unparser::emit_module_init): Don't try to start
      task finder and vma tracker here.
      (c_unparser::emit_module_exit): Don't try to stop task finder here.
      (emit_symbol_data_done): Don't emit static _stp_need_vma_tracker.
    * runtime/sym.h: Remove static _stp_need_vma_tracker.
    * runtime/sym.c (_stp_sym_init): Return error when registration failed.
    * runtime/task_finder.c (stap_register_task_finder_target): Add sanity
      checks to detect double registration or registration after task finder
      was already started.
      (stap_start_task_finder): Sanity check that task finder wasn't already
      started.
