  11 # TODO: Missing tests:
  12 # 1. 'time' target with a source target representing more than one virtual
  13 #    target. This happens in practice, e.g. when using the time rule on a msvc
  14 #    exe target whose generator actually constructs an EXE and a PDB target.
  15 #    When this is done - only the main virtual target's constructing action
  16 #    should be timed.
  17 # 2. 'time' target with a source target representing a virtual target that
  18 #    actually gets built by multiple actions run in sequence. In that case a
  19 #    separate timing result should be reported for each of those actions. This
  20 #    happens in practice, e.g. when using the time rule on a msvc exe target
  21 #    which first gets created as a result of some link action and then its
  22 #    manifest gets embedded inside it as a resource using a separate action
  23 #    (assuming an appropriate property has been set for this target - see the
  24 #    msvc module for details).
