commit 2d767770c8f63cdc3e835a67dac3be7a05507ad5
Author: Josh Stone <jistone@redhat.com>
Date:   Tue Jun 22 17:44:35 2010 -0700

    PR10830: Add pp1() for the high-level probe name
    
    This is a new function which should return the same high-level name that
    "stap -l" gives.  (e.g. syscall.open instead of kernel.function...)
    
    * translate.cxx (c_unparser::emit_common_header): Add probe_point_listing.
      (translate_pass): Add pp1 to stap_probe, predicated on
      STP_NEED_PROBE_POINT_LISTING so we don't waste space.
    * tapsets.cxx (common_probe_init): Set pp1 to script_location().
      (common_probe_entryfn_prologue): Write pp1 to the CONTEXT.
    * tapset-timers.cxx (profile_derived_probe_group::emit_module_decls):
      Fixup CONTEXT->probe_point_listing, since it loops individual probes
      manually.
    * tapset/context.stp (pp1): New, expose the location to scripts.
    * testsuite/buildok/context-embedded.stp: Build pp1().
    * testsuite/systemtap.base/pp.{exp,stp}: Test the difference between
      pp() and pp1().

    Factor out common probe elements
    
    The probes in every tapset type all have a handler (ph) and a
    probe_point (pp), which are initialized and used in exactly the same
    way.  Let's bring that out into a common stap_probe struct.
    
    This will also ease new fields, e.g. for PR10830.
    
    * translate.cxx (translate_pass): Define struct stap_probe, also making
      the decision of whether pp is better as char* or char[].
    * tapsets.cxx (common_probe_init): Initialize a runtime stap_probe from
      any translator derived_probe.
      (common_probe_entryfn_prologue): Take a stap_probe instead of pp.
    * tapset*.cxx: Adjust all tapsets to use the features above.

commit c3df9bce8a33bca599fd86b60b0f2e0db1e60a9f
Author: Josh Stone <jistone@redhat.com>
Date:   Tue Jun 22 13:01:10 2010 -0700

    Add a function for getting a probe's script location
    
    * elaborate.cxx (derived_probe::script_location): New, factor out the
      code for grabbing the "friendly" location of a probe, as specified in
      the script.
    * main.cxx (printscript): Use it.

    Make probe->basest/almost_basest const

commit 74e2cc551da06aee9b803cb6654c81f5bbf1b8cc
Author: Josh Stone <jistone@redhat.com>
Date:   Tue Jun 22 11:42:30 2010 -0700

    Make probe::almost_basest() work
    
    * staptree.h (probe::almost_basest): Probes are the basest, not almost.
    * elaborate.h (derived_probe::almost_basest): If base says 0, then the
      almost_basest is this one.
    * main.cxx (printscript): Use p->almost_basest() instead of collecting
      the entire derivation chain.
