commit f1b9a51a28e577eb6c37af1228e9b84983c04432
Author: Josh Stone <jistone@redhat.com>
Date:   Wed Sep 29 13:51:30 2010 -0700

    Improve the derivation output of STP_TIMING
    
    We can't assume location[0] from the probes in the derivation chain, as
    it may include e.g. an alias with multiple expansions.  Instead, a new
    "base_pp" member tracks which probe_point actually led to each step of
    the derivation.
    
    * elaborate.cxx (derived_probe::derived_probe): Remember the unmodified
      probe_point as base_pp, esp. before any components are rewritten.
      (derived_probe::collect_derivation_pp_chain): New, collect base_pp.
    * translate.cxx (c_unparser::emit_module_exit): Use the pp chain in
      STP_TIMING output.

    Standardize how derived_probes dupe their location
    
    A few of the derived_probe subclasses make duplicates of their
    probe_point so they can rewrite it to something more specific.  This
    patch standardizes that behavior.
    
    It also fixes kprobe_derived_probe and hwbkpt_derived_probe, which were
    rewriting components without making a copy first.

commit 1c9bce2dfcff96c02a30786a479ae125f6317ba9

    Remove the derived_probe ctor lacking a probe_point
    
    In practice, our derived_probes always have a specific probe_point that
    they originate from, so don't let it be omitted.
