+/* This module provide facilities for cloning functions. I.e. creating
+ new functions based on existing functions with simple modifications,
+ such as replacement of parameters.
+
+ To allow whole program optimization without actual presence of function
+ bodies, an additional infrastructure is provided for so-called virtual
+ clones
+
+ A virtual clone in the callgraph is a function that has no
+ associated body, just a description of how to create its body based
+ on a different function (which itself may be a virtual clone).
+
+ The description of function modifications includes adjustments to
+ the function's signature (which allows, for example, removing or
+ adding function arguments), substitutions to perform on the
+ function body, and, for inlined functions, a pointer to the
+ function that it will be inlined into.
+
+ It is also possible to redirect any edge of the callgraph from a
+ function to its virtual clone. This implies updating of the call
+ site to adjust for the new function signature.
+
+ Most of the transformations performed by inter-procedural
+ optimizations can be represented via virtual clones. For
+ instance, a constant propagation pass can produce a virtual clone
+ of the function which replaces one of its arguments by a
+ constant. The inliner can represent its decisions by producing a
+ clone of a function whose body will be later integrated into
+ a given function.
+
+ Using virtual clones, the program can be easily updated
+ during the Execute stage, solving most of pass interactions
+ problems that would otherwise occur during Transform.
+
+ Virtual clones are later materialized in the LTRANS stage and
+ turned into real functions. Passes executed after the virtual
+ clone were introduced also perform their Transform stage
+ on new functions, so for a pass there is no significant
+ difference between operating on a real function or a virtual
+ clone introduced before its Execute stage.
+
+ Optimization passes then work on virtual clones introduced before
+ their Execute stage as if they were real functions. The
+ only difference is that clones are not visible during the
+ Generate Summary stage. */
