//===-- ProfilePaths.h - interface to insert instrumentation -----*- C++ -*--=//
//
// This inserts intrumentation for counting
// execution of paths though a given method
// Its implemented as a "Method" Pass, and called using opt
//
// This pass is implemented by using algorithms similar to
// 1."Efficient Path Profiling": Ball, T. and Larus, J. R.,
// Proceedings of Micro-29, Dec 1996, Paris, France.
// 2."Efficiently Counting Program events with support for on-line
// "queries": Ball T., ACM Transactions on Programming Languages
// and systems, Sep 1994.
//
// The algorithms work on a Graph constructed over the nodes
// made from Basic Blocks: The transformations then take place on
// the constucted graph (implementation in Graph.cpp and GraphAuxillary.cpp)
// and finally, appropriate instrumentation is placed over suitable edges.
// (code inserted through EdgeCode.cpp).
//
// The algorithm inserts code such that every acyclic path in the CFG
// of a method is identified through a unique number. the code insertion
// is optimal in the sense that its inserted over a minimal set of edges. Also,
// the algorithm makes sure than initialization, path increment and counter
// update can be collapsed into minmimum number of edges.
