Modified:
trunk/osprey/be/com/constraint_graph.cxx
Log:
Fix bug765:
Memcpy without arguments is generated in application configuration phase.
To test if lib can link memcpy.
ConstraintGraph::handleMemcopy didn't handle this case, expect src/dest
argument.
Fix is when memcpy arguments incomplete, return early, doesn't mark the actual
parameter modeled.
